I just came across some Feit Smart Dimmers (from Costco) at a very attractive price. Somehow very little information is available as these seem relatively new. Amazon/Alexa detects and controls them, but no bindings in OpenHAB yet. Anyone knows how to get those to work with openHAB?
Edit: I recommend reading the whole thread before reaching final conclusions. I was on a learning curve and some of my initial statements are not very correct. I’ll add this: This is a very capable switch that can be used to control lights from 1/2/3/4 locations. 1/2 locations are easy. 3/4 require the presence of hot and neutral in all boxes, and also, that the Hots be all from the same ‘phase/leg’ of the power into the house. Again, and unlike many other options on the market, the possibilities with this switch are phenomenal. The wiring sometimes is not trivial, and there is a bit of a learning curve. I re-did 16 switches in my house and am very happy with the result. If your specific configuration is not addressed below, ask away, and I’m sure we’ll find something that works for you. Last, as of Jan 2021, these switches are not natively controllable with OpenHAB. One however must flash their firmware and run them via tasmota/mqtt.
