That is a sexy loop. I need the heads up 6 days in advance so I am gonna leave it without the index. Gonna update the Post with my current solution.

Hah, ty. Changed that for the Post cause my message is in German and I got problems enough with my dyslexia…

Yes, my usw case just considers one Valve leading outwards that I need to shut and bleed. Don’t need multiple freezing points for hight presure/isolated pipes. One fits all for me. The loop could be modified for those things. Now it is set to “2”. Not even considering °C or °F (°C in my case). Home Assistenten takes care of that

Thinking about it: i guess i should document my Automation a little more. It is checking the next 6 Days for freezing Temperatur not the current

Yeah, half my research ended in system hang reports
