Picked up a WorksWith In-Wall Dimmer from Best Buy when it was on-sale. It is just a repackaged Centralite in-wall dimmer. In fact, “WorksWith” appears to be owned and operated by Centralite from what I can tell. This device type should work with any other repackaged Centralite in-wall dimmers. I believe they are the Azela model that you can find on their website.
Once the dimmer pairs with the SmartThings hub the buttons stop working on the paddle to turn on and off the light. Instead it sends a button pressed message to the hub and the hub is responsible for replying to the dimmer to turn it on and off. I also could not figure out how to differentiate between pressing the up or down paddle or how to have it dim from the paddle. I am not sure it is even possible. It just sends the same command back to the hub no matter what you press or if you press and hold. So my device type just turns the light on or off depending on its current state. It does dim just find from the SmartThings app.
It also does not report or take in the brightness level correctly. 39% is the max. I adjusted the device type to compensate for this, so everything should dim correctly and the dim level is reported correctly back to ST.
The dimmer is a little pricey at Best Buy right now. But I have a feeling these may get discounted again, so I hopefully this helps out someone in the future!
I have the fingerprints set, so if you publish this device type prior to discovery it should discover it just fine. Otherwise, it will be reported as a “Thing” and you will need to go in and switch it.
