Activate / Deactivate ceiling fans when A/C turns on?

I have two Kasa light / fan switches. I have them turn on when the A/C turns on. Is there a way I can have them revert back to their previous setting when the A/C cycles off?

Create a Routine that turns them off when the A/C turns off?

I understand that is an option. I’m just curious if I already had a fan on prior to the A/C kicking on, could I leave them at their preset setting.

Pretty much, if the fans are on, the A/C turns on, then off, I don’t want the fans to turn off.

Use either a virtual device or a text/number field (using Mariano’s (EDGE Driver-Mc): Aplicaciones Virtuales Mc (virtual Switch Mirror, Virtual Calendar and virtual Switch Board...) driver) to keep track of the state of the light/fan switches when they are manually turned on or turned on by a Routine other than the A/C turning on. Then use that device or field as a precondition in a Routine when the A/C turns off. Something like:

If virtual device state is OFF (pre-condition)
   A/C turns off
Then turn off the light/fan switch

So, if the state of that virtual device is OFF, it means that the light/fan switch was not previously on and was turned on by the Routine that turned on the A/C.

This is perhaps a simpler implementation.
The virtual switch stores information about whether the fan has been started by the first routine. The fan is only started if it is not already on.

  1. routine
If light/fan switch state is OFF (pre-condition)
   A/C turns on
Then turn on light/fan switch & virtual switch
  1. routine
If virtual switch state is ON (pre-condition)
   A/C turns off
Then turn off light/fan switch & virtual switch

A local virtual switch can be made using AWA.

Yeah, much simpler than my suggestion. Should have thought of it :man_facepalming:

Awesome! I’ll look into the virtual switch.

Right now I have it set as

If fan is off and ac kicks on, fans turn on and auto off in 30 min
