Inovelli bulb multicolor driver bug

Hello, I installed 2 inovelli LZW42 and the command "Start Level Change" don't work as supposed. The command don't ramp up or down the bulb. It go instantly 100% bright or off. I try the inovelli driver on their web site and there is the same bug. I try also with generic dimmer driver and with it the bulb ramp up and down correctly. It look to be a problem with this innovelli driver?
I have a C7 firmware

Thanks for your help.

I was also able to reproduce this - the issue is with both the build-in and the community drivers.

However, this same functionality works on the bulbs when using the generic Z-Wave Plus dimmer driver. (It doesn’t provide the other bulb functionalities though…)

@bcopeland, any idea why the “Start Level Change” button wouldn’t work with the stock driver?

No idea.. It used to work… Will re-test


Same issue with a bunch of Inovelli devices. I reported this over there the other day: "Start Level Change" changes lights abruptly - Firmware Discussion - Inovelli Community

Hi @bcopeland did you manage to reproduce the problem?


Inovelli has fixed this in the latest driver version. (See Inovelli forum link above.) I haven't had a chance to test yet, but I'm looking forward to it!

The new driver of Inovelli is working on my LZW31-SN but not on my LZW42.

Someone else can confirm that the bug still be there for LZW42? Near a months ago and no more developpements...

@bcopeland solve the bug!! Thanks hubitat! Inovelli's driver still buggy. The only thing missing in the hubitat driver is the "Dimming speed" setting.

Tagging @ericm so he is aware. Also @mark.amber as he has done some great work on other Inovelli community drivers.

It's fixed for the LZW31. @ericm made the same code change for both drivers. I don't have any LZW42 to test it so I can't say if/why that one is still not working

I juste tested it and can confirm that the “Start Level Change” command didn’t work for me either.

Ok, this should be fixed now.

I’ve had this on my list to re-test for a while and finally got to it today. Unfortunately, it still doesn’t work for me, and for some reason seems to generate a lot of events, which is rather odd…

I tested Inovelli's driver today and look working now on my LZW42 firmware 2.31.

Thanks @ericm

Strange, are you sure you have the latest version? It was working for myself and @marcmale it seems.

The bulbs on which I tested it are outside. I suspect the problem might have been related to problems with the signal getting to the bulbs.
