Need new Node-Red control swicth that incorporates Temp/Timer

The current Node-Red switches for the MVs (Sleeping Zone, Living Zone, Extension Zone and Cylinder) just act as ON / OFF switches.

See: http://192.168.1.100:1880/ui/#/0

They are a bit smarter than that in that they incorporate feedback from the SonOffs they control to affect the switches ON/OFF status. That way they always reflect the current state of the SonOff even when controlled outside the Node-Red switch. See diagram below:









But what I would like is an extra ON selection which would only last for the duration of a set time interval (say 15 mins default) and which would also turn on/off its associated MV dependent on the temperature in that zone.

So three settings:
1) three-way switch: OFF / ON / Timed
2) Time selection slider: 15, 30, 45, 60 minutes
3) Temperature selection slider: 15 to 22 degrees C
