I'd like to find a timer switch, in a style that looks alright next to decora light switches, to control a bathroom fan.
The bathroom fan connects to a 120V AC continuous power source. It has a USB plug that connects to a humidity detector, and it has leads that can connect to a switch that manually turns the fan on. Otherwise it is getting power but is not running. I am using the leads, which I connected to a Romex cable that goes to an electrical box in the bathroom wall. When the two wires are connected, the fan turns on, and it works well with a traditional wall switch. (The fan also runs automatically when the humidity is high but the wall switch is not turned on.)
Neither of the wires that go to the wall switch are 120V AC "hot" power. I checked with a voltmeter, and it appears that one of the wires is connected to the household neutral or ground, and the other is powered at about 90V DC compared with this.
I am trying to find a countdown timer switch that will work for this application. I tried installing a "Leviton Decora Preset Resistive/Inductive 60-Minute Countdown Timer", but it wouldn't work, apparently because it requires that one of the wires being switched is hot 120V AC, from which the timer switch gets power.
Is anyone familiar with a countdown timer switch that will work for this application? Ideally it will allow me to turn on the fan for 15-30 minutes, and ideally it will look alright next to the decora-style light switches next to it (which are in the same electrical box).
The fan is an Aero Pure model ABF110DH. Details are at https://www.amazon.com/gp/product/B07NDG129W
