this is probably a question for @janbonne
several times in the past month Ive had issues when the thermostat looks ok in the gui but will not control the heater
on inspection the backend status is no longer active and I need to ssh in and reboot
ok bit more to this as it stopped again tonight

Hi,
Could you post the results of the following command? The backend should write messages to system log.
journalctl -r -b
it happened again tonight here are the logs

strangle there is nothing in there from the 16th to today when I did an ssh in
You could try this instead:
systemctl stop iothermostat.service
restart the process, by running it from terminal:
/usr/bin/python -u /home/iothermostat/iothermostat-python/iothermostat.py >> /home/iothermostat/iothermostat-python.log
followed by ctrl-z and bg and disown which pauses the back-end, continues it in background and than decouples it from the current terminal so it will keep running if you logout. Just look in the log file to check the process.
Sods law it’s running stable at the min
