Yes, I installed the driver just like I normally would in the ST developer console, and changed it on the device itself. I decided to delete, reset, and re-pair the dimmer, and it came up first-time as the new driver. Also, there's output in the logs.
I then created a simple dimmer rule in RM4.0 and told it to react on changed -- then for the action, control dimmer and FOLLOW event dimmer. Now it works exactly like you'd think.
Not so sure how to get it to follow the button press yet, but it's showing promise.
The only issue I'm seeing is that it's not super graceful when you get near the extremedies of the dimming range, and also it doesn't properly discard duplicate level-changes... it doesn't feel super natural. I think I can tune this on the RM side, but some changes will likely be needed on the driver. I'll see what I can do tonight -- maybe from Happy Hour.
What I'd like to do is change the driver to use a button object instead, so maybe I can get long-press and double-tap out of it. Assuming it even sends that over Zigbee. I saw no indication of that in the Hue app earlier, so we might be SOL and have to work with RM on toggle-logic.
As far as I can tell from what's coming from the device, it doesn't do this either. It would be fantastic if this worked as a button. Pressing it could certainly send "button 1 pushed" or similar since that event clearly happens, though I only have that toggling switch now. For turns, it might be possible to do a little math and fake it in the driver (e.g., send button 2 pushed if turned left, which you can tell if the level is decreasing, send button 3 pushed if turned right with similar logic, etc., but you'd need to be able to "wrap around" when it reaches 0 or 254; with a bit of a delay, you could probably also fake a "release," though I'm not sure that would be useful). However, I'm not sure how well any of that would actually work.
Mike will undoubtedly do much better work than this now that he's ordered one, though how well the limits of the device will constrain the possibilities are TBD.
Okkkay...so I just added my switch to the Hue hub (took all of 15 seconds) and set it to control my Den lights. All I can say is WOW. Super responsive, super simple. I'm very impressed so far. Lutron FTW.
Yes--there's a "mount" you put on first that basically latches onto the switch (this needs to go on in a specific direction), but the "dimmer"/button portion that snaps on top is round and spins freely in all directions, so I can't imagine any reason why this wouldn't work.
The clearance is something I'm concerned with too. I have a sliding barn door that when open, blocks a switch I'd like to use this on. I looked up the measurements and I think I have clearance, but that would depend on how flush the whole thing mounts. So if anyone cares to share how far these protrude from the wall plate I would be grateful.
