I have 2 bathroom fans that my many children like to leave on for hours at a time. I’m looking to add a switch or relay or whatever else might be applicable, in order to shut the fans off on a timer.
I’m not real knowledgeable on hardware for smartthings, so looking for expert help. I find solutions like various z-wave switches, but then I am never sure if they are appropriate for the load. Also was looking at this: http://homeseer.com/pdfs/Aeon%20Labs/MicroSwitch26103.pdf But again: can’t tell if it’s the right solution.
I went with the rotary style, but there’s one bathroom where they don’t even turn on the fan! You enter and it’s like a sauna inside GRRRR, I think that one calls for a smart switch with and a humidity sensor.
I have GE on/off zwave switches in all my bathrooms controlling everything, including exhaust fans.
Besides being controlled manually, they’re also controlled based on humidity levels, or turned off when motion detection has stopped. I did try to use the feature to turn off after a certain period of time, but I prefer the methods I just described.
I then used SmartRules to create a logic that turns the exhaust fans off after 45 minutes of being turned on. Figured 45 minutes was long to clear out the steam or any rose smell. I also did the same for the light in the toilet closets.
Then I replaced the switch that controls the fan with a zwave switch. Using Core, when the humidity rises above a threshold the fan turns on, when it drops below a threshold the fan turns off. Pretty basic operation.
