How to cut power via smart plug at the end of prints or upon thermal runaway?
Background
I don't have a Core One but a Klipper printer, connected to a smart plug with energy monitoring and home assistant.
In HA I monitor the bed, chamber, nozzle temperature and printer status, so when a print is complete, and once all temperatures drop below a threshold (40 °C), first a "system shutdown" is issues (the Linux mainboard performs shutdown) and then after another delay (1 minute) the power is physically cut via smart plug.
I also monitor the power consumption and if it goes 200 W above what I know it's the actual maximum power consumption, I immediately cut the power because something is going wrong. It's not even via Home Assistant automations, it's in the smart plug itself (I flashed ESPhome on it).
My printer being controlled by Klipper and Moonraker, there is a setting in Moonraker to cut the power of a smart plug upon "klipper shutdown", which typically happens when a thermal runaway is in progress.
So, the printer overall is protected against unexpected total power consumption, and also from thermal runaway of a single heater.
The Core One
A friend bought a Core One so I'd like to replicate these failsafes for him as well.
Overcurrent is identical, hard power cut immediately.
Power cut upon idling and low temperature threshold is similar, but do I need to issue a "system shutdown" before a power cut? does the Core One run a Linux or other operating system which benefits from a software shutdown before power cut?
And what about thermal runaway? is there a way to detect it so I can hard cut the power?
