I purchased a zen77 to use in "smart bulb" mode, or otherwise not affect the power to any outlet or fixture, and just rewired our master bedroom light switch and half-hot outlet with a zen77 today. I noticed the blue led was blinking rapidly on the zen77, so after doing some research and reading the instructions, I see that it should not be connected to an outlet.
I replaced the outlet with a standard all-hot one, and capped off the red "traveler" on both ends. The outlet is registering as wired correctly and everything on that end seems to be fine.
Going back to the zen77, I had removed the red "traveler" and just have line and neutral connected now. It continues to blink blue at me, and I'm not sure what I should check next.
Things seem to be running alright since the last power cycle, and I've popped the cover plates back on for the moment. I'm trying to figure out the best way to do the smart bulb control to my Hue group for the room, with the Mirror app being alright, but not the best dimming experience so far (i.e. it doesn't seem to actually send the level update to the Hue group either during or after holding the button to adjust).
Mirror should send an event to the "replica devices" after it gets an event from the primary device (presumably the ZEN77), so I'm not sure what's going on there. But as an alternative approach, I might be in the minority here, but my preference with this type of device is to use them as basically button controllers and ignore any built-in switch or level tracking. I think you'll still need smart bulb mode on the ZEN77 for this, but you can optionally disable any reporting for on/off or level (parameter 21 and maybe others?) -- though it doesn't hurt to leave on and can just be ignored. Then you can use an app like Button Controller to control the Hue group--e.g., button 1 pushed = turn on, button 2 pushed = turn off, etc.
Depending on what Hue integration you're using, you might not be able to get smooth dimming by holding the paddle up or down. The device (or group) needs to have "Start Level Change" and "Stop Level Change," which you'll see on the device detail page. Individual Hue bulbs have this, but Hubitat's built-in Hue integration does not for groups. There are at least two community integrations that do, and then you could use things like "button 1 held" and "button 1 released" to start dimming up and stop. But as-is, you can also just dim up or down a little with a hold — or use multi-taps to set specific settings or "scene"-like behavior.
Otherwise, if you want to look into Mirror, I'd take a look at what events the ZEN77 sends and when. My guess is it's not doing something when expected, so there are no events to translate into commands to "forward" to the Hue bulbs. One of the settings above about how level and switch events do or don't get generated when physical control is disabled may be at play.
I've installed the built in Button Controller app, but not sure which buttons correspond to the on/off paddles on the zen77. I tried setting up Button 1-10 (the zen77 says it has 10 buttons) pushed to turn on my Hue group, and turned on both of the logging options on each of the rules, but am not seeing any response from pushing the buttons on the zen77. I do see the zen77 state changes in the hubitat logs, but doesn't appear to be triggering the Button Controller.
Also, I tried running the Button Controller action from the child app page, and it sure does turn on my Hue group right when requested.
What driver are you using? The built-in driver probably only has two buttons and maxes out at double taps. I'm assuming the community driver I'm aware of (and there may be more) exposes all taps with different numbers. But the easiest way to tell would probably be to keep descriptionText logging (some times called info or event) logging enabled on the device, then try the various taps and holds and whatnot and see what gets logged. "Current States" on the device detail page will also show you the last button number for each event, though unless you keep an eye on what changes when, it's probably a bit harder to use for this purpose.
I was using the Zooz Dimmer Advanced driver, but tried switching to the default zooz zen 77, which presented 2 buttons, but still didn't seem to have much luck.
What ended up working for me last night was going back to the Mirror app, adding the 3 individual Hue lights, and mirroring the switch to those lights instead of the group. That seemed to fix the dimming issue (as I read that this doesn't work for Hue groups for some reason).
And finally, I set the on/off ramp to instant, which made the biggest impact on response time, as it didn't have the 1-5 second ramp time from the switch before it would actually trigger the on/off switch for the bulbs. Now they react very well to the switch.
Only thing left is trying to figure out if there's a better dimming method (which may still go back to the Button Controller or something similar). Looking at the logs, it sends very fine grained updates for dimming, multiple 1% increments per second (i.e. 100-1% over 3 seconds), and it's hard for the lights to keep up with that many changes.
I think if I went with RM or something, and could get the button held / released working, I could have it work in periodic 10% increments or something, which should be much less traffic.
But at least it's functioning decently well, and I was able to remove the Hue Dimmer from the wall next to the regular switches! Things are looking up!
