I have a 2 red series dimmers in the guest bathroom
1 - that controls 2 dumb BR30s that I set the controls to just do on / off not dim
2 - hooked up to the fan in the bathroom and set it to just turn on / off
I had to turn the power off to the house over the weekend, now both switches are acting weird and not sure how to trouble shoot this.
The lights are strobing kind of like when a dimmer is not on all the way
Before I turned the power off, everything was great. Lights turned on and off no issues and same with the fan
now when the lights turn on, they flicker and when the fan turns on its running low like enough power is not getting to it
hhaha yes it would be...... I do think that is the case. I have ALOT of these switches in the house and my end goal is to replace every switch in the house with these. I have also turned the power off to a large range of these switches in the house as well and never had issues
This one issue seems isolated and because I am new to all of this I am sure its something simple I am missing
The LZW31 and LZW31-SN (Black and Red dimmers) are not rated for fans. The LZW30 and LZW30-SN (Black and Red switches) are for up to 300W. See the spec sheets here for more: Knowledge Base Redirect – Inovelli. I'm not saying this is necessarily causing your problems, but it's not something I'd do regardless since the devices are not rated for this application, and you're unlikely to support from Inovelli (and have likely voided the warranty) with this configuration.
Are these bulbs dimmable? While most will do fine if the dimmer applies full power, others may be more sensitive. What you could try doing is making sure the level (via Z-Wave or the dimmer itself, assuming remote or local control, respectively, is not disabled) is at 99 (or 100%, though Z-Wave itself doesn't go that high). If you could try substituting dimmable bulbs at least for testing, that might be helpful--then you can see if they appear to be dim or getting full power. I think they only recommend dimmable bulbs with the LZW31/31-SN regardless, though I can't find that in the documentation at the moment.
Since you mentioned a power outage, one thing I can think of that wouldn't explain all of this but might explain part: I think the original switch or dimmer firmware (can't remember which) had a bug where if you set it to remember the on/off state on restore, it wouldn't remember and would default to off regardless of the setting. I've been running various beta firmwares for a while now, where this issue was fixed, and it wouldn't explain everything you see. I don't recall level being a problem for the dimmers (once on/off was accounted for), but if it is, that could explain the rest of what you're seeing on both devices (though again, I wouldn't do this on a fan).
Along with what @bertabcd1234 I do believe the state the dimmer returns to after a power outage did not return to the proper state in certain scenarios. So you might want to double check that. If you turn the device off and then, through Hubitat, turn the level back to 99% does it still flicker?
As mentioned, we don't recommend using the LZW31/LZW31-SN with a fan, but an LZW30/LZW30-SN should be fine with it.
it is a low powered bathroom fan and I switch the dimmer to on / off functions but I will replace it with a LZW30/LZW30-SN
Right now I am focused on the light. I replaced the bulbs and they seem to dim fine, but when the switch is off the bulbs stayed powered almost like a very dime night light.
Can you try to change "AC Power Type" to Non-Netural, Save Preferences, Set it back to Neutral, and Save Preferences again.
If that doesn't work we could try a firmware update to v1.47. You can do this from within Hubitat. If that doesn't work I'm afraid the bulbs are having issue with the dimmer. Here is the info about the update driver:
If you want to use Hubitat's built-in drivers, the correct driver for the Inovelli Red Series Dimmer (model LZW31-SN) is "Inovelli Z-Wave Smart Scene Dimmer S2." (The non-"scene" drivers would be for the Black Series, model numbers without "-SN," and the LZW31 and LZW31-SN are both dimmers and not switches.)
Which you use is up to you: Hubitat's driver is built in to the platform (so requires no extra steps to use), is supported by Hubitat (so you're more likely to get help if there is a problem), but doesn't support every feature or expose the features in the same way as Inovelli. For example, you'll need a custom driver like Inovelli's to use more than two taps (Hubitat's button model maxes out a double taps, and Inovelli uses other workarounds to get events for every possible combination of taps, holds, and releases), and Inovelli's has other ways to use the "notification" LED on the Red Series beyond a custom command (which both drivers also provide).
