I have a long standing problem with my GE/Honeywell Z-wave Plus dimmer switches where they sometimes won't turn off or on when commanded. I have two GE 14294 dimmers and four Honeywell 39351 dimmers. I'm under the impression that the GE and Honeywell dimmers are identical and both made by Jasco. I also have an Inovelli NZW31 dimmer, Homeseer HS-WD200+ dimmers, Honeywell 39348 switches, an Inovelli NZ30 switch, GE 26933 motion dimmers, and GE 26931 motion switches in my house. All those that I mentioned work fine.
I've ruled out problems with automations (although I think rules that turn off/on alot of lights make it worse). The problem exists even when controlling the dimmers manually from their device page using the on/off command buttons. When control of a light fails, as in clicking the command to turn the light off, "switch" will equal "off" under the "Current States" section even though the physical light is still on. What is really weird is I have the physical switch's blue indicator light set to turn on when the dimmer is off. When the control fails, the blue indicator is turned on (agreeing with the current states section.) So the actual dimmer must really think the light is turned off, even though the physical light is still turned on! Once it gets it a failed state, clicking the off command again rarely has an effect, but occasionally it will really turn off the light. I have found that following a set level = 0 after a failed off command will usually turn off the physical light.
I don't think its a range or interference issue because these dimmers are throughout the house and many are adjacent to the other types of switches/dimmers that always work. On most of the dimmers I'm using JasonJoel's GE Z-Wave Plus Dimmer v1.8.0, but I've also tried the latest 2.3.0 and Hubitat's stock Generic Z-Wave Dimmer driver. All the drivers work the same. I'm currently running v126.96.36.199 of Hubitat. I think I've seen this problem in all the other Hubitat versions.
Has anyone else seen this problem with their GE/Honeywell dimmers? Anyone have any ideas as what could be the problem?
