I am running emonSD-17Oct19, and I have been trying to modify the emonpi firmware to send powerfactor and current values.
However when I build and flash using platformio on the Raspberry PI, my emonTH devices input stop reporting their values, and no traffic for them is seen in EmonHUB.
To rule out the changes I have made, I tried downloading a clean copy of the source from github and building / flashing that and get the same result.
If i flash a copy of latest.hex that I took before starting everything works as expected.
Trying to replicate here I seem to be having trouble uploading the firmware with platformio on the emonpi. But I have been able to successfuly compile and then upload using avrdude.
cd /opt/openenergymonitor/emonpi/firmware
pio run
sudo service emonhub stop
avrdude -v -c arduino -p ATMEGA328P -P /dev/ttyAMA0 -b 115200 -U flash:w:/opt/openenergymonitor/emonpi/firmware/.pio/build/emonpi/firmware.hex
sudo service emonhub start
The emonTH and emontx devices here then appear as normal in the input list.
Logs from the plaformio build and avr-dude upload below, and emonhub.log attached showing that the data from RF remote nodes stops coming in, around 11:30 am this morning when doing a test.
Everything appears to build and upload with no errors, I am getting data coming in from the emonpi it’s self, but not from any of the 433MHz devices.

avrdude-original done. Thank you.

Ive had a manual clearout of the log files, and have tried my build firmware and no longer get the disk space errors when checking the status of the emonhub service. But still nothing coming back from the RF nodes.
One thing ive noticed is that I am bulding an unmodified src 2.9.0 and get a hex file of 52005 bytes, but the one shipped with the emonSD image is 50332 bytes, as is the prebult 2.9.0 on github.
Unfortunatley I didnt make a note of logfiles etc… I’ll keep an eye on the /var/log space over the next few days and see how it grows… It’s not growing particularly fast now…
@borpin Many thanks for your input… @TrystanLea Im guessing what I’ve learned is that the firmware is running otherwise I wouldnt be getting the data from the emonpi node… So there is something funny about my build and the RF config… Could this be a dependency (incorrect version) issue?
