I’m looking for any switch that can be used with HA and can fit in an existing electrical box (single gang or otherwise). Basically it doesn’t (or shouldn’t) have to control a load; I just want to use it as a control button into HA. I’m sure it’s a common scenario: you want to keep power going to a fan or light and control it via HA, but you also want to leave a physical switch in place.
I see there are lots of people working with Sonoffs, but despite my general handiness and comfortability hacking (I stare at Python all day) I really don’t want to get a bunch of hardware, re-flash it, do some soldering, and toss this all in a bunch of electrical boxes; it’s a bit past my threshold of DIY-ness. A ZWave scene controller would work, but it looks it’s not yet implemented in the OZW library. I even considered putting in a ZWave switch (of which I have a number laying around) and not wiring up the load terminal. However a switch with an active terminal and nothing connected doesn’t sit well with me.
Is there really nothing else out there?
