Thermostat with auto disable function
#1
Hello all,
I'm looking for thermostat function/script with 1-bit output. I have a electric heater in the bathroom, which controlled by MDT 1216 actor, and I have also motion detector and window sensor installed.

The idea is to start the heater (electric plug) as long:
"current temp"< "set value temp"
AND window is closed 
AND last motion detected < 1hour

Heater off (electric plug) if:
"current temp" + hysterese > "set value temp" 
OR window opened 

Heater thermostat function off if:
1) last motion detected > 1hour (in case the thermostat was forgotten)
2) OR   "current temp" > "set value temp" for more then 1 hour (in case it's too hot, but somebody enabled the heater).

It's not a PID functtion, just 1 point thermostat with some supervision.
Please advise!
