FAQs

• Due to international rules regarding wireless devices, we only ship within New Zealand and to some Pacific Island nations
• If you are in a Pacific Island nation, please contact us directly first to discuss if our products are compatible and shipping costs
• There is a worldwide network of Davis Instruments resellers. If in doubt about who the best reseller is for your country, please contact Davis Instruments directly

• If the item is in stock and once payment has been confirmed, we ship orders usually within one to two business days
• There are the occasional events during the year where we might take a little bit longer, but these are usually noted in our News section. An example is the New Zealand Fieldays, in mid-June. We close for about two weeks over Christmas and New Year and reopen in early January.

• We do keep most common products and parts in stock
• If you require multiples of a specialist product, we may need to order in for you
• Back-ordered items usually take six weeks from when we order from the factory
•  If you do have a project coming up, please get in touch with us to discuss things in advance, even if things are still up in the air. We will see what we can do to assist

• We use a secure payment portal provided by Wind Cave
• Our website does not handle the payments or save credit card details

• You can purchase via our web shop by credit card (Visa or MasterCard) or direct bank transfer
• We can, if required, prepare an invoice for payment via bank transfer, which includes our bank details.
• All transactions are in New Zealand Dollars (NZD). We are unable to process transactions in other currencies.

• If your order has not arrived within seven working days, please get in touch with us and we will follow up with the courier
• Our orders are usually picked up by the couriers from our office in the afternoon of the day of despatch. Occasionally, the courier picks them up the following morning
• For urban areas in the North Island, delivery is usually 1-2 days
• For urban areas in the South Island, allow 2-3 days
• Allow 2-3 extra days on top of this for rural addresses
• We will send you tracking details. You can track your parcel with New Zealand Couriers or Post Haste for updates. The Product code will be the short prefix (e.g. LH, E40) and the Ticket number a string of numbers
• The couriers both provide network status information may also provide some explanation for a delay. Check with New Zealand Couriers or Post Haste
• However, parcels sometimes do go on a bit of an adventure and can occasionally take a week or two. Why is a mystery to us. Fortunately, it doesn’t happen often

• We ask that you get in touch with us first before sending your station in
• This is because we can usually diagnose problems via a discussion with you
• If we decide your station needs to come in to us, at that stage we will let you know about the paperwork and process, likely costs and wait time

• We do not have the ability to calibrate Davis Instruments stations or sensors
• We can run a functional workshop test of equipment and sensors to check they are still operating within certain limits
• Davis sensors leave the factory calibrated. If you require individual factory calibration reports, you can purchase a NIST calibration at the time of purchase. Please contact us for further information re factory time lines and pricing
• Have a look at the specifications sheets on our resource page. These will give you details about accuracy and in some cases, sensor drift over time. If the spec sheet you need isn’t there, please email us and we will send one out

• Yes, and we keep all the most common parts in stock. Many but not all of those parts are listed on our website
• Don’t see what you need on the website? Please get in touch with a part number or a photo and we will see what we can do. Even quite obscure stuff from decades ago is still tucked away in our store

• We can do. However, we don’t do anything you cannot do yourself. We follow the same basic steps outlined in our handout. If you want to get to know your station better and save some money, we recommend having a go yourself
• Please get in touch to discuss cost, timelines and paperwork before sending your station in

• We have guides for the Vue and the VP2 on our Resource page
• Check out the Davis Instruments videos on our Resource page

• First check is of your system. Conduct a physical check of your sensor suite and remote transmitters. Are the anemometer wind cups and vane spinning freely? Is the rain gauge blocked? Are the cables intact and undamaged?
• Check your console/receiver is plugged in and power jack is firmly seated. Power down and power up again.
• Have there been any changes to your computer system, firewalls or any power outages or lightning storms?
• Check your manuals. There are some excellent troubleshooting tips there
• Check our resources page and FAQs to see if we have some info to help you
• If things are still a mystery, get in touch
• Go to our reporting form and answer the questions
• We need to know all the components your system is made up of. Use our info sheet to help you identify parts and models. Photos are also good
• Email is the best way to get that info to us. It means you can send us photos and screen shots, for the trickier questions it gives us time to mull the answer, and often we have a help sheet we can email back to you

• Yes. The manufacturer warranties (Davis Instruments, Kestrel and all other brands we sell) are all twelve months for manufacturing defects.
• We honour our obligations under the Consumer Guarantees Act
• During the warranty period we will, at our option, either repair or replace the product free of charge.
• Our workmanship on repairs is warranted for 90 days
• See our terms and conditions page and returns policy for more

• Please get in touch. We will do what we can to help and we can usually find a solution
• We cannot honour warranties for products bought from other businesses, so if it is a warranty matter, please contact them in the first instance
• Stations bought overseas will have a different frequency set up to New Zealand and replacement parts may not be compatible. All products we service and sell have to comply with NZ regulations for radio communications, so you may need to convert your system at your own cost. Please contact us, as we can usually convert stations to NZ and then conduct a repair

Sadly, no. Spiders and ants have no respect for the quality or the price of your weather system. The only solution is regular maintenance

Yes. All our products using a radio frequency comply with New Zealand regulations and are labelled with the R-NZ compliance mark

It depends. Many users do not have any ongoing fees. Two groups of users will have annual subscriptions or plans:

1. People upgrading from the free, Basic Tier of the Davis website, weatherlink.com. The website has three tiers: Basic, Pro and Pro+. Basic is free, the other two are paid. See more information below in the FAQ section on weatherlink.com
2. Customers with EnviroMonitor systems. These have annual data plans, which include the Pro Tier of the website and cellular charges

Sensor suites:

• The wireless sensor suites and transmitters have solar panels and super capacitors with a backup lithium battery
• The cabled sensor suites are either plugged into a Weather Envoy or EnviroMonitor IP Gateway and use mains power or, if plugged into a 6803 EnviroMonitor Gateway, are powered by the Gateway’s solar panel

Consoles and receivers:

• The legacy consoles, WeatherLink Live, Weather Envoys, and EnviroMonitor IP Gateway run off mains power and have the option of adding backup batteries
• The 6313 WeatherLink Console uses mains power and has a built in battery, like a tablet

It depends on your Davis system set-up but there are several options:

• On the Davis website, weatherlink.com
• On your phone, via a  Davis app, usually the WeatherLink app
• On the WeatherLink console
• On the WeatherLink Desktop Software on your PC Windows computer
• Integrated into your system using an API

• Nothing lasts forever! Keep in mind that New Zealand’s island weather is notoriously tough on weather stations, especially with the wind blowing the rain sideways. Many of us live near the sea and some of us near geothermal activity, which doesn’t help
• Having said that, you can expect your Davis station to keep going for years
• The stations are made of good UV-resistant plastic. Like the solar panels, that UV plastic lasts well
• Some sensors, such as the temperature/humidity sensor, will wear out over time. These can be replaced on the Vantage Pro 2. (The Vue will need the entire PCBA replaced)
• The backup battery will need replacing every few years
• Regular services to check for ants and spiders and that the wind vane and cups are spinning freely are recommended to help your gear last longer
• The Vantage Pro 2 has been manufactured for almost 20 years and we can still supply parts to keep those early ones going
• When possible, the improvements to Davis sensor suites have been made to be able to retrofit to the earlier models
• Check out our wide range of parts for the VP2 and the Vue in our web shop and our tech support in our FAQs and Resource Page

Yes! For both Android and iOs devices. Actually, there are three:

• Davis Instruments WeatherLink app. This allows you to access your current/most recent data from weatherlink.com and view your station data with historic highs and lows. Free to download and you don’t even need to have a station. Anyone can download this, search by station name or location and save stations as favourites. There are almost 500 stations on the map for New Zealand alone.
• Davis Instruments EnviroMonitor app. This is for EnviroMonitor users only and is used for set up and diagnostics
• Davis Instruments Mobilize. Mobilize lets growers focus on frost, growing degree days,  chill accumulation and irrigation requirements. This is for EnviroMonitor users and others with a Pro tier (paid) subscription to weatherlink.com

There are a lot of phrases and terms used by Davis

• Integrated sensor suite, ISS and sensor suite: all refer to a collection of sensors mounted together with a transmitter. There are two varieties, the Vantage Vue and the Vantage Pro 2 (VP2). Usually an ISS compares favourably to the price of one sensor and transmitter
• Vue and VP2: The two varieties of Davis sensor suites, Vantage Vue and Vantage Pro 2
• WeatherLink: usually refers to a Davis software or data product. There are the data loggers and serial interfaces, the PC Desktop software, the new console, the Live, the app and the website: all use WeatherLink in the name
• EnviroMonitor (EM): The latest Davis system. Two options: a cellular Gateway that uses the Spark network to get data to weatherlink.com and the WeatherLink app or an IP Gateway. The EM systems add extra sensors using the EM Node
• Weather Station: Usually (but not always) used by Davis to mean a bundle (sensor suite and console) sold together

Have a Davis and not sure what it is? Check out our helpful info sheet ‘IDing Davis Components’ on our Resources page

• All Davis sensor suites give you air temperature, humidity wind direction, wind speed, rainfall
• Consoles and Weather Envoys give you air temperature and humidity and barometric pressure
• EnviroMonitor Gateways give you barometric pressure
• You can add extra Davis transmitters and Davis sensors to get other measurements, such as solar radiation, UV radiation, soil moisture, soil temperature and leaf wetness
• With the EnviroMonitor systems, you can use four sensors in any configuration with a Node with any Davis sensor and a variety of third party sensors
• These third party sensors allow measurement of: carbon dioxide, water depth and level, flow meters, PAR (PPFD), pressure sensors, pressure switch, water potential, water quality and weight

• Our website. There is lots of information in the web shop (including prices), resources page (which has spec sheets and the latest Davis catalogue) and other sections of this FAQ page
• You Tube. Davis Instruments have their own channel, with numerous videos about their products
• By downloading the Davis WeatherLink app and trying it yourself. It is free for the Basic Tier. Search on the map and save any nearby stations as favourites
• By getting in touch with us. Email us or call. Come see us in person at the New Zealand Fieldays at Mystery Creek

• For almost all of our customers, we recommend wireless Davis systems
• The exceptions are a) sites where there are a lot of radio transmissions and a cabled variant can give peace of mind and b) with EnviroMonitor Gateways where the cabled sensor suite can be powered through the Gateway and mounted on the same pole
• Cabled sensor suites are more prone to damage, including lightning strike and cable damage
• Use of a cabled sensor suite and Weather Envoy does not allow you to include soil moisture or other remote transmitters
• Cabled products are not compatible with the WeatherLink Console or WeatherLink Live

There are a number of factors that will point you to one Davis system over another one. You have some decisions to make:

• Decide what data you want: what parameters you want to measure and how often
• Consider what options you might want in the future
• Decide how you want to view the data. On your computer and off-line? On your phone?
• Consider your site: do you have internet? What distances are involved? Are there buildings and shelter belts in the way?
• We have systems for most situations. Check out our Davis Enquiry Info sheet on our Resources page. It will give you an idea which system will work in the different scenarios above
• Get in touch to discuss. We enjoy helping you find the most cost-effective system for your needs. If our products don’t match your needs, we will try and point you in the right direction

Lots of different people. Our customers include:

• Businesses needing to meet resource consent conditions
• Companies monitoring wind conditions, such as ports, quarries, adventure activities, agricultural contractors, pilots and crane operators
• Growers interested in frost alerts, chill hours or growing days
• Farmers and growers interested in soil moisture and temperature and/or irrigation
• Researchers, farmers and growers interested in staff or stock welfare concerns, such as heat stress, or predicting horticultural or agricultural pests or disease
• Engineers integrating weather monitoring into construction projects and building management
• Educators
• Weather enthusiasts

• It is a good idea to do the set-up in the comfort of your own home or office. Get the receiver set up, check the transmission is coming through, then take the sensor suite outside and check the transmission before digging the post hole and installing. This is especially true if you have a remote site
• Davis Instruments gear likes time when setting up. Why, we don’t know! It may take 5, 10, 15 minutes for a console to start receiving. EnviroMonitor nodes can take a few hours to start reporting. Once they are going, they will keep chugging away for years, but patience on set-up day is required
• For us in the Southern Hemisphere, the solar panel will need to face north. The North Americans would set up their Vantage Pro 2 (VP2) sensor suite with the solar panel facing south (to get maximum sun) and the anemometer facing north (to give accurate wind direction). We can install the wind sensor facing south and put in an adjustment of 180 degrees if we don’t want it blocking the solar panel

• Davis stations are designed for owner installation
• The Davis manuals are excellent and will step you through the stages
• Davis Instruments also have a You Tube channel with some great video demos
• All Davis sensor suites and outdoor units come with U bolts and all the parts required to mount them to a pole or post. If you have your own pole or post at home, you don’t require anything else
• We do stock mounting options if you need one of them: the Davis 7717 mounting pole kit and Davis 7716 tripod

• Generally, choose a site that is flat, above grass, and where your wind readings are not blocked by trees or buildings
• Keep your sensor suite away from heat radiators, such as concrete, asphalt, and air conditioning units
• The World Meteorological Organisation measures temperature and humidity at 1.5-2.1m and wind at 10m, but choose a height that is meaningful for you, your staff, crop or animals
• Consider how to keep your sensor suite safely away from stock, orchard machinery and other site hazards
• Choose a site that gives you a good representation of the area whose weather you want to measure. For example, for the orchardist, this might be inside a shelter belt, under canopy
• Consider how easy it will be to maintain your sensor suite, as leaves and spiders can cause blockages
• Avoid sites that may need special safety requirements, such as a roof with limited access

• All Davis sensor suites (ISS) are set to transmit on transmission channel ‘ID 1’. Most people do not change this factory setting. So if you know there is another Davis nearby, when installing your sensor suite, consider using another of the 8 channels. Instructions on how to do this can be found in the ISS manual
• If the owner agrees, you could just buy a receiver such as the WeatherLink Console and get data from their station. It might be worth checking the reception/distance to your house first
• Download the Davis WeatherLink app and have a look. Not all Davis stations are online and not all online stations are set to Public, but you might be able to find the station on the map and save it as a Favourite and get hyper-local weather data for free

• Yes.
• Once you get your data to the Davis website, weatherlink.com, click on the Share and Upload button.
• You then have a choice of four different Embed options (wide or slim format, full screen or signature) and embeddable links for each

Yes, you can. See more below in the weatherlink.com section of this FAQ

• Yes you can, using the WeatherLink console, or either of the legacy consoles
• Learn more about how to set up audible alarms in the WeatherLink console manual on our resource page

• Yes, once your data is uploaded to weatherlink.com
• For Google, say “OK Google, talk to WeatherLink” to start the linking process
• Once linked, you can just say “OK Google, get the current conditions”
• To ask Alexa, the Echo device must hear the phrases “ask WeatherLink” and “current conditions”

Yes, you can:

• Use a WeatherLink Console and keep it off-line. Please be aware that firmware updates and some of the console features, such as forecasts, rely on the console being connected to the Internet
• Choose an Envoy/USB Data logger combination to download your data on your computer only
• Choose an Envoy/Serial Interface combination to integrate your data into your control system only
• Choose a WeatherLink Live and use it with a local API set-up. Learn more at https://weatherlink.github.io/weatherlink-live-local-api/

Yes, you can:

• If your data is being uploaded to the Davis website, weatherlink.com, you can choose to keep your station as Private. It will not show up on the map or in searches. (It is stored on Davis servers. Please check their terms and conditions for more information)
• The other way to obtain privacy is by not uploading your data to weatherlink.com and keeping it off line

Yes. There are various ways to share your data:

• Once your data is on weatherlink.com, you can keep your station set as public so everyone can see it. Friends, colleagues and customers can download the WeatherLink app and view it on their phone or computer
• With a paid Pro Tier of weatherlink.com, you have six Pro Shares which allow a different WeatherLink account holder to view your station, even if it is set to Private
• With a paid Pro Tier of weatherlink.com, you can email an Excel spreadsheet of your data to any email address

• Yes, you can. Once your data is on the Davis website, weatherlink.com, you can upload your data from there to WOW, Weather Underground, The Citizen Weather Observer Program (CWOP) and Global Learning and Observations to Benefit the Environment (GLOBE)
• More information about how to do this can be found on the MetService website
• It used to be the case that you needed to buy third party hardware to get your data to WOW, but since Davis added the website upload, this is no longer necessary

• Name your station after your business. Upload your weather to the Davis website, weatherlink.com and upload from there to third party sites such as WOW and Weather Underground
• Display your current weather data as an embedded widget on your website or email
• Use a TV monitor or console in your foyer displaying weatherlink.com showing your current weather data
• Use signage near your weather station or on your website to show people how to download the WeatherLink app and save your station as a favourite

We support a number of New Zealand manufacturers. Please get in touch with us to discuss

• Yes. Davis Instruments has a new portal for software designers. This includes an updated version of the weatherlink.com v2 API. You can find this portal here: https://weatherlink.github.io/
• There is a local API for the WeatherLink Live. Learn more here: https://weatherlink.github.io/weatherlink-live-local-api/

• Your Davis weather system has a number of sensors that collect data, such as wind speed, temperature, and humidity. As well as this data, your system will calculate other variables, using the true data and a series of calculations
• Check out our info sheet ‘Weather Station Variables’ on our Resources page to see a comprehensive list of measurements and derived variables that Davis systems are capable of

Examples of derived variables include:

• Heat Index and Temperature Humidity Sun Wind (THSW) Index: Useful when thinking about the impact of the weather on people or animals, such as overheating, wind chill and dehydration
• Potential Evapotranspiration (ET) Rate: Useful when monitoring plant growth and water usage, such as irrigation
• Wet Bulb Temperature (Delta-T): Used when spraying to select the best conditions to maximise spray coverage

• By  wireless system, we mean one where the receiver is: a WeatherLink Live, WeatherLink console, a wireless Weather Envoy or the legacy Vantage Pro 2 console
• Davis offer two repeaters for the wireless receivers, the Standard repeater and the Long Distance Repeater (which requires two antenna)
• Each site is unique and it is worth spending some time assessing your site, doing a needs assessment and future proofing your system
• These days, it might be cheaper and more useful/versatile to extend your internet/Wi-Fi system with a booster device instead of adding a repeater that is only for use with your weather station
• Get in touch with us to discuss before ordering

• By mounting the Gateway and Nodes higher above the ground or the highest crop height
• By adding an EM Antenna to your Gateway or Node. The antennas can be used Node-to-Node or Node-to-Gateway
• Both the cellular Gateway and the IP Gateway can have an external antenna installed
• There is no need to have pairs of antenna – so simply add an antenna where added transmission range is required
• You have two options for your EM antenna: the 5dBi and the 8dBi versions

• Check batteries in your repeater and your transmitter, especially if you get your data on sunny days but not overnight or on overcast days. Repeaters work hard in difficult conditions so battery lifetime can be reduced in some circumstances
• Go to your site and take a look. If your system has been in place for a few years, consider what has changed since you installed it. Have trees grown up or shelter belts grown denser? Some pruning might assist
• You also need to consider what is under your repeater. Has your crop grown? Try mounting your devices higher or trimming plants below your repeater.

• Wireless transmission means line of sight, so it is best to mount your transmitter, repeater and receivers where there are no obstructions between them
• Generally, mounting your devices as high above the ground or the highest crop level as possible provides the best transmission
• Wet foliage will reduce transmission more than dry foliage so if you find you are missing data on rainy days, this may be the cause
•  Your transmission range can be affected by a range of site factors, such as antenna height, the terrain and foliage, buildings and other structures, and radio frequency interference, so it can take some experimentation to get it right
• Common building materials such as wood or glass only minimally affect transmission while steel will affect the range significantly. Locating your devices in windows can help
• When speaking about transmission range, the maximum distances refer to optimal conditions. Due to minor obstructions and interference, typical distance will likely be about 50-80% of the maximum. If walls, thick shelter belts or high radio frequency interference are factors, range may drop to as low as 20-40% of the maximum

• We generally recommend using two standard repeaters rather than using a long range repeater
• This is because you can locate the repeaters to “go around corners” or “over hills”
• Another advantage is that the standard repeater does not require two additional antennas
• These options are for a wireless Davis system (excluding the EnviroMonitor systems)

• Yes, you can
• All the sensors come with instructions sheets about installation
• Check out our Resources page for more info

• Yes, we do. You have two choices:
• A Davis system that uses a wireless receiver (that is, a WeatherLink console, a WeatherLink Live or a wireless Weather Envoy) and a soil station
• A Davis EnviroMonitor system that requires a Gateway (cellular or IP) and a Node

Monitoring your soil moisture and soil temperature will help you, over time, get to know your soil better and learn how much water is stored and how your soil responds to rain and irrigation.

Potential benefits of monitoring your soil and acting on that data include:

• Increased production and improved crop quality
• Increased effectiveness of fertilisers and pesticides
• Better control of diseases
• Reduced water and energy consumption
• Reduced costs

• Yes, you can
• In fact, it is a good idea to if you plan to export your historic data from the website, as if you have NZ options set up in your Excel spreadsheet, and you export a copy with USA date and time options, your data will be missing or incorrect
• Log in to weatherlink.com, click on the person icon on the right side of the screen. Select Unit Measurements from the menu options. This will bring up options for measurements of wind, pressure, and several others.
• To adjust your time and date displays, log in to weatherlink.com, click on the person icon on the right side of the screen. Select Display Formats from the menu options

• Pro+ Tier: paid annually in advance on the website. Cost is USD$ 8.95 per month. The annual cost is about NZD$175 (depends on exchange rate)
• There are discounted three year plans

No, you don’t. The Pro subscription is included in your annual EM Gateway service plan

• You will need to choose the station you want to use with the Pro Upgrade and apply it to that station. This is because some users have more than one station and might have Basic Tier access for some stations and Pro for others
• To apply the upgrade, log into weatherlink.com and click on the cog icon next to the device tier. Then select ‘Upgrade to Pro’

• Use the Bulletin page to view your current data from your station. You can arrange the tiles
• Set up alarms
• Upload your weather data to a selection of other sites, such as Weather Underground and WOW (used by the New Zealand MetService)
• Search the WeatherLink map (by location or station name) for other stations around New Zealand and the world
• Use the two versions of the WeatherLink map: for temperatures and weather conditions or for air quality
• Use the Graphs tab to select sensors and weather variables to graph over time*
• Use the Data tab to view and download your historic data*
• Use the Mobilize tab to view your custom chilling hours, growing degree days, frost forecast and soil moisture monitoring*

* requires the Pro Tier of the website

• Check that your date settings on weatherlink.com are set to the New Zealand format of: day/month/year as if your computer or Excel format setting is NZ format and your WeatherLink account is American format, the data will be affected.
• See the question above in the FAQs on how to change the time and date display

Basic Tier:  If you are happy looking at your data on your console and the WeatherLink app.  (The WeatherLink Console does have a number of ways to view your historic data on the console)

Pro Tier: If you want to do any or all of the following: download your historic data, use the Mobilize app, use the Chart or Graph features on weatherlink.com, if you want a faster third party upload or archive time (five minutes compared to 15 minutes for the Basic Tier) or share your station data with another WeatherLink account (Pro Tier allows you to share with six other users)

Pro+ Tier: Only a very few of our customers need this. The Pro+ Tier gives all the Pro Tier benefits plus access to the Davis Integrated Pest Management (IPM), one minute upload rate and archive interval, and ten Pro Shares

These tabs require a current subscription to the Pro Tier of the website. If you have not subscribed, or your subscription has lapsed, you will not be able to access these tabs

Yes, it can. By replacing the main board in the unit, we can convert the 2G/3G EnviroMonitor to a 6803 EnviroMonitor Gateway. Your data plan will stay the same. Please get in touch with us to discuss, as your Gateway will need to be sent in to our workshop

Yes, it can. By replacing the main board in the unit, we can convert the 2G/3G Connect to a 6803 EnviroMonitor Gateway. Your data plan will change over to an EnviroMonitor data plan. Please get in touch with us to discuss, as your Connect will need to be sent in to our workshop

• By mounting the Gateway and Nodes higher above the ground or the highest crop height
• By adding an EM Antenna to your Gateway or Node. The antennas can be used Node-to-Node or Node-to-Gateway
• Both the cellular Gateway and the IP Gateway can have an external antenna installed
• There is no need to have pairs of antenna – so simply add an antenna where added transmission range is required
• You have two options for your EM antenna: the 5dBi and the 8dBi versions

• Both the IP and Cellular Gateway allow you to add any four compatible sensors to each EM Node.  EM Nodes allow the use of the Davis sensors and a selection of third party sensors. See our Resources page for a list of compatible sensors
• The EM cellular gateway allows you to monitor in real time remote sites that do not have internet or power
• An EM IP Gateway may give an extended transmission range over the wireless Davis WeatherLink systems and allows the use of the Nodes
• EnviroMonitor systems have a annual data plan, which does make them more expensive than a WeatherLink system
• Both systems use the same sensor suites (usually the Vantage Pro 2 sensor suites)
• To sum up: the EnviroMonitor systems are our most expensive Davis product, and they are a great solution for specific situations. However, for people with internet on site and who only need a smaller range of data, the wireless Davis systems are a cheaper alternative

You can use any Davis sensor and a number of third party sensors. See our Resources page for a PDF list of compatible sensors

Choose sensors for following parameters

• Soil moisture
• Soil temperature
• Soil salinity
• Water level
• Leaf wetness
• Weight
• Pressure sensor
• Pressure switch
• Flow meter
• Solar radiation

• We usually have some of the Meter Group (previously Decagon) soil sensors in stock
• The rest we order in as required by our customers. If you are interested in a specific sensor for your EM node, please get in touch. We can let you know price and a delivery time frame

Yes, the 6803 EnviroMonitor Gateway is 3G/4G compatible

• To access your historic data from your AirLink, yes
• However, if you already have a Davis station and a Pro subscription, you will not need another one

No, the AirLink is a standalone product

Just plug it in to mains power and it will use your Wi-Fi system to connect directly to the Davis website

Access your AirLink data:

• Via the Davis website, weatherlink.com
• Via the Davis app, WeatherLink
• Via Amazon Alexa or Google Home
• By viewing it on your WeatherLink Console (data comes via weatherlink.com)

• The AirLink measures particulate matter (PM) (sizes PM1, PM2.5 and PM10) to give an indication of air quality
• It shows real time levels of PM and Air Quality Index readings
• It also provides temperature, humidity readings and dew point, heat index and wet bulb calculations

• In our web shop. See photos and prices and more info about the AirLink there
• On our Resource page, where you can find our FAQ sheet and the spec sheet and manual
