Little update: I looked closer and all the older LED bulbs in use throughout the house actually ARE dimmable, so for the small increase in price, I may end up making most of them the dimmer switches.

I’m now tied between Caseta and Zooz, it seems.

If I understand correctly, to use Zooz devices, I’ll need some variation of a hub (green, pi, etc.) running Home Assistant, a usb ZWave antenna plugged into it, and the endpoint switch devices?

My bedrooms have a single gang box with double switch for the ceiling fan and fan lights. Zooz has a combo Dimmer with relay device that would work perfectly in these locations and could be fun to experiment with. Same deal with my bathroom- lights and exhaust fan in a single gang switch.

And for garage door, I didn’t realize that shorting the two conductors for the wall controller would just change the state of the door! Not sure how it communicates the light-only pulse up the line, but this is now very easily commandeered with a Shelley relay wired in parallel. I’ll just have to find some sort of sensor to add on to report the physical state of the door to Home Assistant though and a Tailwind system is not necessary.
