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
ethernet 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 wireless or 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,

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 6:
Planning Your System.
Power-up and Connect your Gateway.
3. Connect your Gateway to WeatherLink.com with the EnviroMonitor app.
4. Power up the Node. See page 10:
Power-up and Connect the Node.
5. Connect the Node to the Gateway with the EnviroMonitor app.
6. Mount the Node. See page 13:
Mount the Node.
7. Add and Install the sensors with the EnviroMonitor app.

Planning Your System
Before installation, plan 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, as
shown below.
• The Gateway should be placed in a window or as close to the outside of the
building and as close to the Nodes as possible; higher is better.

Make a Sketch
It is helpful to make a sketch of your installation to get an idea of where the
Gateway and Nodes should go.

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.
