I've been thinking about replacing the manual knob timer on attic fan with a smart switch so we can use voice commands and timers to turn it back off.
The main thing I don't know if, or how it can be accomplished is I don't the fan to be able to be turned on unless certain windows are open.
If it's turned on, and a rule evaluates to false will it turn back off fast enough? My fan is powerful enough, without windows open it will suck out the pilot light on my water heater.
I guess I answered my own question. RM will quickly turn the switch back off if a window isn't open. Built a virtual switch and a couple contacts to test with.
If you have a switch with smart bulb mode, you could set it so that pressing the switch doesn't control the load.
- Press the switch (fan doesn't turn on)
- Check the conditions
- If conditions met, turn on the fan
Oh that's a good idea. Like one of my zooz switchs that has "disable local control". I like that a lot!
You should check out my app for tracking the windows.
Cool. Basically I would use the child device in my RM rule instead of the individual sensors, right?
