I recently had to replace my node-RED server because the Pi it was running on died. I moved my flows over and I have one particular one that publishes to emonhub/tx/16/values, which in turn causes my Emonhub to tell the RFM69Pi to send radio packets outbound.
I doesn’t appear to me that the radio packets are going out. They certainly don’t seem to be arriving at the destination, but I don’t see anything in the emonHub log that would indicate they are being sent. I’m using the same emonHub configuration file, the same RFM69Pi, the same receiving nodes as I was when it was working last week. The only thing that has changed is that the version of everything in the emonHub and node-RED stack is newer, and I went from a Pi 3 to a Pi 4.
Any suggestions for me?
Here is the history of how I got this working in the before times.
