So if you ever wondered how your temp graph looks like live while the pt100 is working its way out of the hot end block:
I was lucky having the temp graph on a 2nd monitor and noticing it.
Solution: Stopping print, putting that thing back in and rethightening the screw.
Further improvement: Ultimaker is now powered via a 16A Sonoff Power Switch:
Ultimaker and Sonoff are both bound into Home Assistant.
New Automation: If printing temp drops below 175°C while status is „Printing“ cut the power.
