I’m trying to understand how Node-RED connects to Groov. I set up a simple flow with a modbustcp node which connects to a modbus device I have. I can get data and display it in a debug node without a problem. Next I added a Groov Read node,gave it a tag name that matches the one in the datastore I created in Groov build, gave it the API key for the admin user per the Weather Underground tutorial that I found. So far, so good.
In my simplistic brain I figured I would take the output from my modbustcp node and stick it in my Groov Read node and it would display correctly on my Groov page. How easy is that? But it doesn’t work. As soon as I connect the two, I get an error (see below). I get Bad API Key followed by unknown device name. I’m thinking this may be because the modbustcp node is a different device it may need a certificate.
