I have a self-built Pi 3B with the latest RFM69 board and emonHub software. It acts as the RF I/f for my home setup. Originally, it had the old version of the RFM69 but I upgraded to the new protocol when the old board failed. That was back in January and it’s been solid until now.
Several times now, the RFM69 board has appeared to stop receiving frames from the emonTH nodes. The problem does coincide with the installation of the emonTX5, which required changes to the emonhub.conf file; so I can’t exclude that. However, it’s OK for most of the time.
I have logging set to DEBUG but even so, there’s very little to help me. The following is the log from early this morning until I rebooted at 08:06

You can see some frames from the emonTX on Node 28, but then nothing.
After the reboot, there’s nothing until I intervened again this afternoon. In desperation, I did a dist-upgrade and rebooted. It’s running OK right now; but for how long? I seeing loads of the following messages
2025-06-28 15:34:53,762 WARNING SPI No radio packets received in last 300 seconds, restarting radio

I’ll try and move it without it losing RF connectivity.
