Welcome to Your EnviroMonitor System
An EnviroMonitor System
includes a Gateway and a number
of Nodes, each with up to four
sensors that form an advanced
mesh network operating at 902 928 MHz (868 MHz in the EU).
The Nodes transmit the sensor
data to a “mesh parent,” either the
Gateway or another Node. The
Gateway then sends the data via
cellular connection to
WeatherLink.com.
EnviroMonitor can be customized
for different sized installations.
Each Gateway can receive 20 or
more Nodes. Additional Gateways
can be added to your account to
receive data from another set of
Nodes.
A Davis cabled GroWeather
Sensor Suite can also be plugged
into the Gateway.
This manual will show you how to
set up both the EnviroMonitor
Gateway and Nodes. If you are
just installing a Node and have
already installed the Gateway, you
can skip to page 12:

Planning Your System
After determining which sensors you want and where you want to install them, make
sure you have the correct number of Nodes to support those sensors.
The maximum distance between two Nodes and a Gateway and a Node will vary
depending on many factors including environment, height, terrain, and RF noise.
To get optimal transmission range:
• Ideally, locate the devices with unobstructed lines of sight between them. A large
hill or large metal barrier will block signals. If transmitting under a canopy or in
an orchard, range will be reduced.
• Mount the devices as high above the ground or the highest crop height as
possible. The higher they are mounted, the longer the transmission distance.
• Try to mount the Gateway on a rooftop or pole so that it has a good “view” of the
area where the Nodes will be mounted.

Tips for Siting the Gateway and Nodes
Siting the Gateway
• The Gateway should be mounted where it has the strongest cellular connection
and a clear, open “view” of the sky with good sunlight for the solar panel.
™
™
• You may plug a cabled Vantage Pro2 sensor suite, such as GroWeather,
directly into your Gateway. If you do, you will need to choose a location that is
within reach of the sensor suite’s included 100’/30 m (extendable up to 1,000’/
300m) cable. See page 11:
Add a Vantage Pro2 Sensor Suite (optional).

Note: The radio in the Gateway is not compatible with the radio in wireless Vantage Pro2
stations.

™
Siting the Nodes
• Ideally, the mesh network will be most effective at “self healing” any
temporarily impaired transmission paths if each Node has more than one way
to reach the Gateway. While the system is designed to handle a mesh, a “star”
or nodes in single lines, it is a good idea whenever possible to site each node so
that it is within transmission distance of either two (or more) other Nodes, or
the Gateway and another Node. A Node can even be installed simply to
transmit data from more distant Nodes to the Gateway, without any sensors
installed in it. By planning the system’s “transmission mesh,” data can be
relayed in from the most remote corner of your installation.
™
The best installations allow Nodes to
transmit to more than one Node or to
a Node or Nodes and the Gateway.
• Nodes can also be used to transmit data around or over obstacles, such as hills.
™
™
Get around an obstruction by using a Node with no sensors as a relay.

use or location so you can easily identify this Gateway if you install others.
8. Follow the prompts to finish adding the Gateway.
9. Once done, you will be prompted to add a Node. Before adding a Node,
however, you should mount the Gateway.
Mount the Gateway
Confirm Cellular Strength
The best way to determine cellular connection is to take the Gateway to your
proposed location and use the EnviroMonitor app to see the signal strength.
In the app, choose this Gateway. Open the Menu icon in the upper right
corner. Choose Connection.
• If the app shows cell connection, but the RSSI is less than 4, the cellular signal
is present but weak. It may be strong enough to work, but it would better to find
a location with a stronger signal:10 or higher is preferable. If there are large
trees or buildings nearby, they may be obstructing the signal between the
Gateway and cell tower. Try changing the location to avoid the obstruction. If
your selected location is in a low spot, try moving to a higher location.
Tip: If the app shows no cellular signal at the chosen location, try a second choice
location. Remember to choose Refresh in the app and wait a few minutes to see the
strength at the new location.
Tip: Mounting the Gateway may be easier if done by two people.
The Gateway can be mounted on a pole or a flat surface such as a wall or post.
It is important that the Gateway be mounted so that the solar panel gets the greatest
amount of sunshine: the solar panel should be facing south (in the Northern
Hemisphere) or north (in the Southern Hemisphere).
9
Tip: While south is generally appropriate for the Northern Hemisphere (and north in the
Southern Hemisphere), your goal is to maximize direct sunlight on the solar panel. If
your location does not have a full sunrise-to-sunset exposure arc when the panel
faces south, you should face your solar panel toward a point midway in the existing
arc to maximize panel charging.
Mounting on a Flat Surface
Attach the Gateway to the mounting surface in the desired location using the lag
screws and backing plates as shown below. Use a pencil or a center-punch to mark
the location of the pilot hole.
Mounting On a Pole
Mount the Gateway onto a pole with the U-bolts, backing plates, washers, and hex
nuts provided.
Note: Use the smaller U-bolts on a pole with an outside diameter of 0.84'' to 1.84'' (21 mm
to 47 mm). For mounting on square perforated tubing or larger diameter poles up to
1.94'' (49 mm) outside diameter, use the larger U-bolts.
10
Add a Vantage Pro2 Sensor Suite (optional)
Add a cabled Vantage Pro2 integrated sensor suite (ISS), such as GroWeather
(product number 6820C), to your system, to get rain, wind, temperature, humidity
and solar radiation data to the Gateway.
Note: Wireless Vantage Pro2 integrated sensor suites are not compatible with this Gateway,
1. Open the Gateway door.
2. Remove the plug from
one of the holes in the
bottom of the Gateway
and run the sensor suite
cable up through it.

3. Outside the shelter, wrap
a split grommet with an
oval hole (included in
hardware kit) around the
cable and push the
grommet securely into

Grommet
ISS Cable
the hole. Plug the cable
into the ISS cable jack.Close the door.
4. Secure the sensor suite cable to the post or pole with the included zip ties. Do
not use staples to secure the cable.
Note: If you are mounting the Gateway and the sensor suite together, you may find that the
100’/30m cable that comes with the sensor suite is too long. You may use the
included 8’/2.4 m cable. If you use this shorter cable, pay special attention to
preventing the sensor suite from shading the solar panel on the Gateway. (See
below.) Davis also has two other cable lengths available for purchase: 40’/12m,
(product no: 7876-040) and 200’/61m (product no. 7876-200).
If your installation is between 0° and 45°
latitude, North or South, and you mount the
Gateway and a Vantage Pro2 sensor suite on the
same pole, it is important to make sure the
sensor suite does not shadow the Gateway’s
solar panel at midday, especially in the summer.
If possible, mount the sensor suite and Gateway

so that they are at least 4 feet (1.2 m) apart. You
can also rotate the Gateway 45° to the east or
Gateway
™
west (depending on your location). If you do
rotate the Gateway, you may need to return it to
face south (Northern Hemisphere) or north
(Southern Hemisphere) in the winter.
You can also add a Davis Angle Shelter Bracket, product number 6671, which will
increase the Gateway’s tilt to 30
°.

1. Remove the D-cell battery compartment door and install 4 D-cell batteries
according to the + and - marks in the battery compartment. The Node will
power up. The mesh status LED will indicate connection. Replace the door.
IMPORTANT: Install the D-cell batteries FIRST. Make sure they are firmly installed and not
tilted outward. The battery compartment door prevents the D-cells from vibrating
loose; be sure to reinstall it correctly.
2. Remove the battery pull tab from the lithium battery and make sure the battery
is firmly in place.
3. Plug in the solar panel cable.
13
Connect Node to Gateway
1. Take the Node and smartphone to the general location in which you wish to
install your Node. Make sure the phone’s Bluetooth (BLE) is on.
2. Open the app on the smartphone.
3. Open the door of the Node. (This turns the Node’s BLE on.) The BLE status
LED will blink blue. See the illustration on page 12:
Contents of Node.
4. In the app, select the Gateway to which this Node will send its data.
5. Tap Add Node.
6. Bring the phone close to the Node.
7. Follow the prompts in the app as it finds the Node and connects it to the
Gateway. This transmits the Gateway’s identifying information to the Node
and allows its data to be received by the Gateway. Having specific
identification for each Gateway/Node pair allows you to have multiple
Gateways without cross transmission.
Using the app, you will be see this Node’s serial number appear on the list for
the Gateway.
You will know the Node has found its “mesh parent” (a Gateway or another
Node) when you see the BLE status LED go solid blue. If it cannot “find” its
parent, try moving the Node to a different location. If the location of the Node
cannot be changed, consider installing another Node closer to the parent, to
act as a repeater. It does not need to have any sensors installed.
When the connection is complete, the mesh status LED will turn solid green.
See the illustration on page 12:
Contents of Node.
Install the Sensor(s)
The list of sensors your EnviroMonitor system supports is constantly growing.
Check www.davisinstruments.com/em-sensors for the current list.
Note: Wiring diagrams for each sensor are shown in the EnviroMonitor app.
Each Node has four sensor ports.You can install the sensors before or after
mounting the Node. For example, if you plan to mount the node on a tower, you
will want to install the sensor first.
1. Install the sensor in the environment per the
manufacturer’s instructions, making sure the
sensor is installed within cable reach of the Node
when it is mounted.
2. On your smartphone, open the EnviroMonitor

Maintenance
The solar panel on your Gateway or Node will perform well even with dust on it.
However, you can keep the panel charging optimally by periodically cleaning any
bird droppings, heavy dust, dirt, snow, leaves, or insect nests or webs from the
solar panel. The frequency of cleaning will depend on your installation, but at
least once a year. Those near roads or railroad tracks, for example may collect
more dust and dirt than those in the center of a field. Use a soft, damp cloth to
remove any debris from the solar panel.

Have you configured your Gateway in the EnviroMonitor app? If you have done
so and the cell LED blinks red, your Gateway may be installed in a poor cellular
coverage area. Leave the Gateway in place for at least 30 minutes to see if it can
connect. If not, you may need to relocate the Gateway or contact Technical
Support. See page 26:
How can I tell if my Gateway battery voltage is getting too low?
Contacting Davis Technical Support.
Our server will monitor your battery voltage and will trigger an e-mail warning if
it should get critically low (approximately 14 days of power). The e-mail will go to
both the registered customer’s e-mail address as well as the alarm e-mail address
(if one has been set up). You can also see the battery power in the app: choose this
Gateway, then Gateway Power.
What do I do if my Gateway battery is low?
The EnviroMonitor features a robust battery and solar panel. It is designed to
recharge and last for years. If your battery is low, you need to determine why the
solar panel is not recharging the battery. This is usually due to something shading
the solar panel (such as vegetation, snow, or dirt), or the solar panel becoming
turned away from the sun. Check your installation to make sure sunlight is
reaching the solar panel.
My installation is in a low light area. Can I add another solar panel?
Yes. You can add an Extra Solar Panel Kit (product number 6616).
Can I use AC power to charge the Gateway battery?
If your installation is in a low-light area or an area with prolonged periods of time
where temperatures stay below -4°F (-20°C), charging may be severely
diminished. You may use Davis’s Optional AC Charger Kit, product number 6710,
to charge the battery. The kit allows you to replace the solar charger with AC
power. The adapter has a universal input (100 -240V, 50-60 Hz) and will work
anywhere in the world. (A wall-plug adapter may be necessary for use in some
countries.) In a cold environment, you will need to bring the Gateway into a
warmer environment (above -4°F/-20°C) to charge the battery with the AC
Charger Kit.
I’m not getting data from my Node to the Gateway?
• Make sure the D batteries in the Node are installed all the way in. Sometimes
the appear to be but are actually tilted outward, preventing connection.
• Make sure the green sensor adapters in the Node are aligned properly and not
offset.
• Make sure the screws on the sensor adapters are very tight.
• Make sure none of the sensor cables are pinched in the Node door.
If these steps don’t solve the problem, consider mounting the Node and Gateway
higher above the canopy. See “To get optimal transmission range:” on page 2.)

Configure the Node using the
EnviroMonitor app.
My Node can’t connect to the Gateway or mesh parent.
Give the Node more time, at least 15 minutes, to negotiate a connection to the
mesh network. If it still cannot connect, the Node is not within transmission
distance to a parent. To solve this you can relocate the Node closer to the Gateway
or another Node, or you can install another intermediate Node between it and the
mesh parent to help it connect to the mesh network.
How can I tell if my Node batteries are getting too low?
The mesh LED will be solid or blinking amber to show that the Node’s batteries
are low. See the table above. You can also see the battery power in the app: choose
this Node’s Gateway, then this Node, then Node Power.

Appendix A: Adding a Long Range Antenna
a
Add a high gain external antenna to your Gateway and/or Nodes to increase the
transmission distance of an EnviroMonitor mesh network up to 10,000 feet (3,000
m). Antennas can be used for either Node-to-Node or Node-to-Gateway
transmission.
Choose either product number 7676, 5dBi; or 7678, 8dBi. The table below shows
estimated transmission ranges of each of the antennas. (The antenna that comes
installed in your Gateway or Node is a standard dipole.)
Antenna Ranges

5dBi External 2,600’ 790 m 4,000‘ 1,200 m 6,000’ 1,800 m
8dBi External 5,000’ 1,500 m 7,000’ 2,100 m 10,000’ 3,000 m
Using a Long Range Antenna with a Gateway
1. Open the Gateway.
2. Using a Phillips-head screwdriver, remove the two screws attaching the smoky
plastic cover over the Gateway’s electronics.

3. Remove the installed mesh antenna by unscrewing it from the connector. You
may need to use a 5/16”(8 mm) wrench or small pliers.
4. Remove the solid grommet from the hole on the right side of the bottom of the
Gateway shelter. Run the connector end of the antenna cable up through this
hole and place the split grommet with a round hole (included with antenna)
around it and push the grommet up into the hole to seal the shelter.
5. Screw the external antenna cable into the connector. Do not over-tighten.
6. Replace the plastic cover, making sure the antenna cable exits through the
channel on the right.
