node-red-contrib-gotenna

Node-RED nodes to send data to and receive data from a goTenna mesh radio modem.

Install

Run the following command in your Node-RED user directory - typically ~/.node-red

npm install node-red-contrib-gotenna-0.0.1.tgz

then cd into the node_modules/node-red-contrib-gotenna directory and install the goTenna driver

./install

This assumes running on a Linux box of some sort, requires sudo (root access), and uses python3, otherwise you may be able to just

sudo pip3 install goTenna-0.12.5-py3-none-any.whl

Then, once Node-RED has been started, you should see two goTenna nodes (an in and an out) in the nodes pallet.

Configuration and Use

To configure the nodes, you'll need to add your sdkToken as well as a gid.

Once the nodes are correctly configured, deploy the flow and turn on the goTenna connected via USB. The light should blink fast, and then the Nodes will show a status of "Online, Battery: xx, Temp: yy" which means that Node-RED is correctly receiving information from the goTenna. You should then be able to send and receive messages.

Leave the gid field blank in the output node to send a broadcast message, or add the specific gid of another goTenna to send a private message.

Gotchas

I've noticed some occasional problems with private messages, so if you have any unexpected disconnects, use broadcast instead, once I find a fix, I'll update the node.
