Upgraded H801 from v8.1 to v15.0 lights not off with dimmer op minimal.

[marcelgln]

I have upgraded a H801 which is configured with 5 independent PWM channels. When setting the sliders to minimal, LED still are a bit on. When switching the channel "off" LED's are off (so dimmer at min != off)
DimmerRange is set from 0-100
When I set the slider to minimal and request Channel1 in the console it reports: {"Channel1":1}

Any suggestions how to let slider 'min' to be the same as 'off' ?

Sounds like you have enabled SetOption77

Do not power off if a slider is moved to far left

I was not aware of this option, it is the behavior I have. Just checked it: {"SetOption77":"OFF"}
So it's not the case, might be a bug the the last version (15.0.1) ?

If you upgraded directly from version 8.1 to 15, without following the upgrade flow, that could result in a broken setup.

With version 15, I'm not seeing what you describe, on a H801 split using SetOption68.

It was not my intention to preserve my settings, so I just upgraded from 8->15
I did a reset6 before applying a new configuration.

Just tried the following: reset6 -> select H801 module -> setoption68 1

The issue is still there, with slider to left, there is still some visible LED lighting. using the button I can switch it off.

With the old Tasmota version 8.1, I did a test matching yours, 5 PWM channels and SetOption68 1. Result was that the sliders would not go down to value zero per channel, for that you do indeed need to push the buttons. Results include values like:
{"POWER1":"ON","Channel1":1,"POWER2":"ON","Channel2":1,"POWER3":"ON","Channel3":1,"POWER4":"ON","Channel4":1,"POWER5":"ON","Channel5":1,"Color":"0303030303"}

BTW. Now, I'm not sure what I tried when I said to not be seeing what you described with version 15, as I cannot repeat that now. Also here, I do see the PWM channels go to very low level. And I do not see this as any different from version 8.1.

When it comes to SetOption77, I now think that this is only for Dimmer values, but with SetOption68 you instead get lower level Channel values.

Thanks for testing. I had not tried it yet using MQTT (how I finally use it). Using MQTT I can set the channel to 0 and it actually works as expected. So in the end it seems only related to the slider in the web GUI (which I mainly use for test/debug), so finally no problem for me.
