EmonTx not updating emonPi

The serial port is definitely enabled on the pre-built image. I can see from reading your posts on the top of this thread that your RFM69Pi was working fine in the past.

I think I know the reason why Emoncms is not updating, it’s caused by the dist-upgrade updating the version of Mosquitto. I won’t go into details you can read this thread if your interested:

To fix you need to run emonPi update via local Emoncms (Setup > Admin > emonpiupdate) then reboot. Mosquitto MQTT server should now be running. You can check with:

sudo service mosquitto status

and view the log, you should see mosquitto version 1.4.10

head /var/log/mosquitto/mosquitto.log


Even if the data is not getting any further than emonHub we should be able to see the serial data coming directly from the RFM69Pi. You can view the serial data using minicom:

sudo minicom -D /dev/ttyAMA0 -b38400

Stopping emonhub is not necessary. When minicom is open press ‘v’ to return the RFM69Pi’s version number and RF config. Exit minicom with [CTRL + A] then [X then Enter]. Please paste here any data you see in minicom.

If you are still not having any luck I could send you a replacement RFM69Pi to test next week
