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:

The steps for setting up your EnviroMonitor system:
1. Plan: What sensors do you need and where? Decide where you will install the
Gateway and Nodes. See page 2:
2. Power up your Gateway. See page 7:
Planning Your System.
Power-up and Connect your Gateway.
3. Connect your Gateway to WeatherLink.com with the EnviroMonitor app.
4. Mount the Gateway. See page 9:
5. Power up the Node. See page 13:
Mount the Gateway.
Power-up and Connect the Node.
6. Connect the Node to the Gateway with the EnviroMonitor app.
7. Mount the Node. See page 16:
Mount the Node.
8. Add and Install the sensors with the EnviroMonitor app.

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).

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.
