I'm trying to control Hue bulbs with Zooz ZEN72-800LR Z-wave dimmers, a C8, Hue bridge, CoCoHue, and Button Controller. On/off works fine, but holding down either dimmer paddle has a huge amount of latency. When I release the paddle, the bulbs continue dimming for 2-3 seconds so it's extremely difficult to dim to a desired level (in either direction) without overshooting it by a lot. This happens both with a single hue bulb or with a hue group. Anything I can do to speed this up? I don't have this issue with Inovelli Z-wave or Zigbee switches.
That param controls the total time to dim from on to off which isn't the issue. I can set that to anything and I still have seconds of delay from input to response. Faster values there are even worse really because it gets even harder to not overshoot considering all the latency.
The first thing I'd try to figure out is where the delay is happening. For example, you may find that it is between the real-world event of releasing the paddle and the generation of the "button 2 released" (or whatever) event on the hub. Alternatively, you may find it is between the generation of this event and the sending of the stopLevelChange() command, the sending of stopLevelChange() and the actual stopping, some combination of these, or perhaps something else entirely.
With all logging enabled on your Button Rule and debug and descriptionText (info) logging enabled on the Zooz and Hue devices, the timing of this should become clearer and would give you -- or anyone here -- a better idea of where to start troubleshooting.
