I was actually starting working on a custom button that could control this stuff. If your goot with a soldering iron you could probably get it to work well. The circuit board has a built in mains to 3.3v regulator, so I just removed the relay and the existing uC, cut a few wires and added a few resistors and connected it directly to an esp8266. You can then use st_anything or just the arduino library to implement it in a WAF friendly, powerful way. I was also planning on baking in functionality so instead of just going through smart things (which, since device handlers are in the cloud, would take a little while to operate, thus killing WAF) it would actually send the JSON packets directly to the controller, whether it be a H801 or something else. That way it would basically work locally, kind of like direct associations in z-wave.
Anyway, here’s the thread. Advice on create new Multi-Light Switch. I thought about having it work in a few modes, like one button will cause the holding up/down to cycle through the color wheel, one would cycle through presets, stuff like that. It’s in my pile of half started projects that I plan on spending more time with in the future, whenever that may be.
