Need to run a python script every 10min via terminal, however the phone suspends it after a while. Are there any commandline args that will prevent this?
I need it to run overnight as it will trigger an alarm if one of several nearby fires is too close to us. The workaround is to use a night-time clock app at the same time but its not 100% reliable.

Maybe make it a systemd timer instead of fighting the suspend?

Looks promising but couldn't get it to work:
timedclient-qt5 -a'whenDue;runCommand=python3 /home/nemo/Downloads/redzone.py' -e'APPLICATION=test;TITLE=test;ticker=10'
My guess is it requires extra formatting of the command, or needs to run via installed qt app?

Assuming you are atm interested in easy options rather than optimizing pm behavior, executing
mcetool --set-suspend-policy=early
-> Allows phone to power off display and touch, but cpu is kept alive -> a polling script should work without extra effort, but battery consumption increases significantly.
mcetool --set-suspend-policy=disable_on_charger
-> Disables suspending altogether, but only while phone is connected to charger. An attempt is also made to keep touch panel powered on (and hence display too to some extent) - which might cause touch issues on some device types.
Note that even if systemd timers / timed alarms are successfully used for waking up the device to trigger the script, the device might still suspend during script execution. This can be worked around by wrapping the script exec with keepalive-tool e.g. while something like "sleep 120" could end up getting suspended, "keepalive-tool sleep 120" ought not.
