DAVIS 6801 EnviroMonitor Gateway and Node User Manual

DAVIS 6801 EnviroMonitor Gateway and Node User Manual

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 have up to 32 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: Set Up Nodes and Sensors.

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: Planning Your System.
2. Power up your Gateway. See page 7: Power-up and Connect your Gateway.
3. Connect your Gateway to WeatherLink.com with the EnviroMonitor app.
4. Mount the Gateway. See page 9: Mount the Gateway.
5. Power up the Node. See page 13: 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.
  

Note: This illustration shows how installation height affects general transmission distances under ideal conditions. Many variables affect transmission distance. Results will vary based on environmental conditions. For longer transmission distance, add a Long Range Antenna to the Gateway and/or Nodes. See page 21: Appendix A: Adding a Long Range Antenna.

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.

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.

Power-up and Connect your Gateway

Install the EnviroMonitor App

1. Install the EnviroMonitor app on your Smartphone.
   Find the app by searching for the Davis EnviroMonitor app in the iOS App Store or Google Play Store.
   
   EnviroMonitor App
   The EnviroMonitor app will guide you through creating an account on WeatherLink.com, adding the Gateway, adding Nodes to the Gateway, and adding sensors to the Node.
   

Power up your Gateway

1. Remove all cardboard and packing materials from inside the Gateway.

2. Connect the battery.
   The Gateway is shipped with one battery cable (the red, or positive cable) disconnected to prevent battery drain. Connect the red cable to the red terminal.
   
   IMPORTANT: If putting your Gateway into storage, disconnect the red cable.

3. Plug the main power cable into the jack.
   

Connect the Gateway toWeatherLink.com

1. Make sure the Bluetooth (BLE) function on your smartphone is on.

2. Open the app and choose Sign Up to create an account, or Log in if you have already created an account

3. Tap Add Gateway.

4. Bring the phone close to the Gateway.

5. If a message appears that an upgrade has been detected, select Upgrade.
   Upgrading can take several minutes.
   Tip: The LED flashes to show that the Gateway’s BLE is on. If it is not flashing, press the recessed touch pads. See the illustration on page 6: Contents of Gateway (6802A shown) for the location of the recessed touch pads.

6. The LED will turn solid blue when the Gateway has successfully connected to your smartphone.

7. Once connected, enter a name for this Gateway. Choose a name based on the 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).

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.

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 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 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°.

Hardware Kit

Requirements & Tools for Installation of Nodes and Sensors

• Included precision/miniature slotted screwdriver; ideal size: 2.5 mm or 3/32”; see actual size image of screw head and screwdriver blade at right.

• Four D-cell batteries

• Smartphone with EnviroMonitor app installed. See page 7: Install the EnviroMonitor App.

• Wire cutter/stripper and wrench

• Mounting pole or post
  Note: You should install Nodes starting with the Node that will be closest to Gateway, then working outward to the Node furthest from Gateway. This allows each Node to establish a connection with the Gateway or a Node that has already been installed.

Power-up and Connect the Node

Make sure the EnviroMonitor app has been installed on the smartphone you will be using to install the Node. It will guide you through adding Nodes to the Gateway that has already been installed.

Power Up the Node: See illustration on page 12: Contents of Node.

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.

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 app and select this Node. Tap Add Sensor. From the menu, first select the sensor type, then the specific sensor. Follow the wiring diagram in the app to correctly wire the sensor into one of the green 6-wire sensor connectors. Using a 2.5mm (3/32”) precision slotted screwdriver, loosen the appropriate screws and insert the bare wires.

3. Tighten the screws very tight.

4. Insert the 6-wire sensor connector into the sensor port indicated by the app.
   Make sure it is aligned properly and not offset.
   Note: If the Davis sensor has an RJ-plug on its cable, use the Davis RJ Adapter, product number 6860. Or, you can remove the plug and strip the wires.
   
   Try not to strip the covering back so far that the bare wires can touch each other when the connector is plugged in, but make sure the clamp in the sensor port is closing on wire, not plastic. (About 1/4” [6.4 mm] of exposed wire is ideal.)

5. Run the sensor cable down and out of the box through the bottom. Make sure it will be enclosed by the foam when the Node door is closed.

6. When all sensors are installed, close the Node door, making sure all cables are against the foam and not the hard plastic of the door. Use included zip ties and adhesive mounts if desired.
   
   Note: Make sure none of the sensor cables are pinched in the door; especially the cable on the the sensor installed in Port 1.

Mount the Node

The Node can be mounted on a pole or a flat surface such as a wall or a wooden post.
It is important that the Node 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).
Tip: Mounting the Node may be easier if done by two people.

Mounting On a Fence Post or Pole
Mount the Node onto a fence post or a pole using 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.

Mounting on a Flat Surface
Attach the Node 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.

Note: To increase transmission range from Node to Gateway or Node to Node, you may replace the internal mesh antenna with an external Long Range Antenna. See page 21: Appendix A: Adding a Long Range Antenna

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.

My Gateway can’t access the cell network orWeatherLink.com

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: Contacting Davis Technical Support.

How can I tell if my Gateway battery voltage is getting too low?
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.)

Radio LED is solid amber.| The Node is connected to a mesh parent and its batteries are low.| Replace D-cell batteries.
Radio LED is solid red.| The Node has not been configured.| 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

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.)
