Wireless Light/Fan Switch Reccomendations
I have a light/fan combo in a bathroom that are controlled with a single switch. I want to control them separately, but running a new wire would require ripping out drywall, which I don't want to do. It is in a guest room, so it can't be controlled with an app, even though I know there are ways to give guest access to certain home automation systems.
The power runs up from the floor, through the switch, and then up to the fan, so I have power at both locations. The wiring for the fan is in the attic, so putting something up there is easy.
What I imagine exists is a remote double relay that can be controlled by 2 physical switches(preferably single gang, but I am prepared to open up the wall a bit to install a double gang box). I would prefer that the relay be powered by 120v, rather than a 12v device that needs a plug somewhere, but its not a total deal breaker.
Anyone have any ideas?
I suspect there's a Sonoff smart switch which will do what you need. I have one which I control with a physical switch, it's very useful. You can configure them for all sorts of things and they're small enough to fit into a lot of back boxes so they plumb right into existing infrastructure.
Shelly also make similar things - I don't have any of their devices personally, but I have heard good things.
Both will also talk to most home automation systems so you can add more Smarts if you want later.
Are you sure? Not sure if you've tried sneaking a peak through the gap around the gang box, or with a small endoscope, but if the wire is not secured to the stud then it's as easy as taping some 14/3 to the end of your 14/2 super good and then gently pulling from one end or the other.
I only mention it as I recently did this myself, and it was almost way easier. I did end up having to remove the gang box to so I could get the wire the rest of the way, I was pulling towards the gang box. But I was going to have to do that anyways since I was replacing it with a double gang, it just didn't occur to me to remove it before the wire pull.
