Alright, in my recent introductory post, I warned of a series of stupid questions, and here is the first one!
For complicated reasons, I need/want a dimmer switch to control/dim a lamp on another circuit (lamp was previously on a switched receptacle prior to room re-arrangement...extension cord is a no-go). So, my wife wants a 'normal' switch to control the lamp, and a smart bulb is a no-go AFAIK as I need a pretty bright bulb. We also want dimming capability going forward if possible. So, I'm attempting to achieve this goal via an Inovelli Red Dimmer (with no direct load) controlling a Leviton DZPD3-2BW plug-in dimmer on another circuit via z-wave association. Inovelli tech support has indicated that this should work, though they obviously can't guarantee anything as they haven't validated this configuration themselves.
So, I set the 2 devices up in hubitat and used the inovelli z-wave association tool to create groups 2 and 4 associations for on/off and dimming control. On/off control from the switch works splendidly. Dimming is really weird. I need to hold hold the dimmer paddle on the switch until the LED indicator shows that dimming should be complete. Only then does the lamp START dimming, as long as I continue to hold down the switch paddle. Once dimming finally begins, the dim rate is almost imperceptibly slow - like at least 30 seconds from start to finish. If I stop holding down the switch dimmer paddle, dimming stops immediately (or at least appears to...hard to tell with the sloooow dimming rate). Same situation when increasing the brightness. If I dim the using the plug-in dimmer controls directly in hubitat, it works just fine. Issue is only when trying to dim from the switch.
So, to resolve, I've ensured that I have the latest Inovelli non-beta firmware (1.48, I believe) and the correct driver for the red dimmer. The plug-in dimmer is a little trickier as there's no specific driver. I've seen from prior threads in this community that the DZPD3-2BW should work with the DZ6HD driver. I've also tried the generic zwave dimmer driver - no difference. I've mucked around with the dimming and ramp rates in the Inovelli settings, none of which seem to have any impact. There isn't too much to change on the plug-in dimmer side, though as mentioned earlier, I can control the plug-in dimmer just fine directly from Hubitat.
So, that is my situation. Have I missed something obvious? Was this a dumb idea to begin with? I know I can control the dimming with scene control on the switch, but was hoping to avoid this...again, meeting the stipulation from my wife of a 'normal' functioning switch. Do either/both of these devices need to be the first items in my home automation pile of shame? Any suggestions or troubleshooting tips would be appreciated!
