smart switch advice
 

i am installing a whole house fan and want have a countdown timer installed with it. At a previous home we had a manual switch wired to a timer like pictured. So i can press 30 minutes or 60 minutes and the fan will turn off at the end of the time.
Are there any smart switches that can accomplish this, that i can turn on the timer from an app. I dont need any other functionality like scheduling or anything like that. Just a countdown timer.

This is my go-to for controlling WHF’s. I like being able to keep the fan on for more than an hour.

I am literally working on this now. I jsut built a home and went with leviton switches and made the entire house smart with Apple HomeKit. I have tv's, audio, switches, pool, sprinklers, etc.. all on home kit. Was a breeze to install and so far working perfect. Many of the new hole house fans like quiet cool come with RF wireless controllers.

I think most of this woudl work and you can use from the app or looks liek two will work from home kit
