I’m looking for a smart home solution use two switches in my living room (EU), in order to make them just smart enough so I can control some devices. The setup isn’t very complex in itself, and I’m pretty sure it’s doable - I’m just unsure what I’d need in order to use these switches in a ‘smart’ capacity…
This is what I had in mind:
- On-off switch, connected to a single light with three Hue filament bulbs. I’d like this one to always be powered, as to make them always controllable
- On-off switch, which should be connected to a light which isn’t in use at all. Once this one is ‘smart’, I could control all other smart devices in the living room like a ‘turn off everything’-button.
I have a Hue bridge and a Home Assistant instance running in my home.
With regards to wife-approval-factor, I’d rather leave the original switches in place, but I’m open to suggestions. I hope one of you can steer me in the right direction.
Edit: if this isn’t the right community for the question, I’d understand, but I wasn’t sure where to put it otherwise… I’d be open to suggestions to that too.
Every wall switch I’ve seen (in US) has an attachment for a ground wire, except really ancient ones, and every “Romex” style wiring includes a ground wire
My house is an older one with steel junction boxes, so those need to be grounded, but plastic boxes obviously do not.
So, my experience may be limited but I’ve always seen switches grounded and always seen everything support grounding.
As someone further up said, it’s the neutral that is the problem. I don’t know if it’s code or convention, but older wiring tends to use “switch loops” without a neutral, while more modern wiring is “pass through” and does. Even before smart switches, this was needed for things like lighted or programmable switches
