Hello,
I’m trying to setup my H801 running Tasmota in my new OH3.
A normal Sonoff switch is already running, so MQTT works.
My problem is the setup for the color.
I added an channel for POWER and another for color, but I’m not able to do anything at the color (no options).
I did not find any guides for OH3. Can anyone share his setup?
(H801 means RGBW Light, Power, Brightness and Color)
Thank you!
Can anyone please share his settings?
Still unsolved 
I liked OH 2 much more
Can you explain your problem a bit more? You have a Tasmota RGBW light. You have configured a power channel, which works. You have configured a color channel, but color does not work? How exactly does it “not work”? Are there any error messages? What happens if you change the color item? Do you see MQTT messages when changing the color item? From what you write (“I’m not able to do anything at the color (no options)”) I don’t understand what doesn’t work (except “everything”, which is not helpful…)
My setup has a Tasmota RGBW light bulb. The tricky par of talking to this device is (in my opinion) switching between color mode and white mode. I use four channels for this: Power, Brightness (dimmer), Color Temperature for white and Color (HSB).
My channel configuration looks like this (note I have configured this via GUI, not text files: In the Thing definition there are three tabs: “Thing”, “Channels” and “Code”. Since it is more compact to post I give (parts of) the “Code” tab here, instead of screenshots):

Each channel is linked to a corresponding item (like your Ambilight Schreibtisch Color, which looks perfectly fine). If all items have “Property_Light” set you can now operate all items in MainUI, in tab “Equipment” on the card “Lights”. In my case it looks like this:
After pressing the color picker button (white square beside the switch in the last line) and selecting a color the openHAB sends the command cmnd/Wifilight06/HSBCOLOR 207,0,100 to Tasmota and the light turns blue(-ish).
When changing the color temperature to a value between 153 and 500 the bulb is white again.
Does this help?
Hi,
thank you so much for your answer @Fleck!
It already helped me since it provided more informations about the channels I have to use.
I didn’t know about the “HSBCOLOR”.
I’ve tried setting it up now, but it doesn’t work.
And the code snippet:
channels:
- id: ambschreibtisch

configuration:

stateTopic: stat/tasmota_schreibtisch/HSBCOLOR
transformationPattern: JSONPATH:$.HSBColor
The only difference I can see is the
which isn’t shown in my code snippet
And now even the power button isn’t working anymore (not sending or changing state)

Hmm, which version of openHAB are you using? I am on version 3.2 and I think there was a change in the MQTT binding some time between 3.0 and 3.2 regarding the color modes.
I‘m running on 3.2.0 too.
Perhaps you are a victim of this bug: MQTT Channel Type "color" causes exception when using lowercase "hsb" in file or when using UI · Issue #10117 · openhab/openhab-addons · GitHub ?
I don’t think this was the direct reason, but when troubleshooting I saw that the option
colorMode: HSB
was missing. Clicked around a bit (reselected HSB, save, …) and it was in Code.
Now this error isn’t shown anymore and Power Works.
But I’m still not done 
Color(HSB) still has no options:
and when using the Brightness Color Temp changes from warm white (set via Tasmota) to an “artifical cold white”.

Is it possible that Tasmota isn’t using the stateTopic? (Or openhab not sending a request)
It isn’t shown in MQTT Explorer.
When I use the Power Button in OpenHab, stat gets created in the Explorer. But only for Power
When I send “State” in the Tasmota Terminal it is shown in the MQTT Explorer
… but still not updated in OpenHab.
Strange. I see the stat/tasmota_name/HSBCOLOR mqtt topic coming from Tasmota. Can you send the HSBOLCOR command manually over MQTT Explorer (cmnd/tasmota_schreibtisch/HSBCOLOR) with contents e.g. 135,0,100 and check if you see the corresponding stat message in MQTT Explorer and in openHAB?
I can see the message in the MQTT Explorer when sending the HSBColor command:
Thing in OpenHAB is still null.
But I just saw, that even the Power in OpenHab doesn’t get updated (/POWER, …). But in this case it can be turned on/off via openhab.
POWER must be upper-case
commandTopic: cmnd/tasmota_schreibtisch/POWER
stateTopic: stat/tasmota_schreibtisch/POWER
And for HSBColor try
stateTopic: stat/tasmota_schreibtisch/RESULT
Thank you!
Power works, but Color not yet:
Executing the JSONPATH-transformation failed: Invalid path '$.HSBColor' in '{"POWER":"ON"}'
when i switch the power button.
When i update the color via Tasmota no error, but also no change in Openhab.
The problem seems to be: if power is toggled, there is only the power in the result message (MQTT Explorer). Color, … is missing
{"POWER":"ON"}

If you change color or dimmer in OH, can you see the commands in MQTTExplorer like this?
cmnd
LED_Strip
Dimmer = 70
HSBCOLOR = 340,100,70
and what is your Tasmota version?
I’m on OH 3.3 M3 and Tasmota 10.0.0
Wow! Thank you!
It seems that everything works. I’ll do more tests in the next days.
I’m surprised it only works with Regex, I haven’t seen it when researching.
Also Thanks @Fleck!
I’m on openHAB 3.2.0 and since yesterday Tasmota 11.1.0. Before it was 10.X
I’m on a way to turn on the warm white leds: (Color/Dimmer does work!)
- id: White
channelTypeUID: mqtt:switch
label: White
description: ""
configuration:
commandTopic: cmnd/tasmota_schreibtisch/WHITE
stateTopic: stat/tasmota_schreibtisch/RESULT
off: "0"
on: "100"
It works, but throws the warning:
[ab.binding.mqtt.generic.ChannelState] - Command '{"POWER":"ON","Dimmer":100,"Color":"000000FF00","HSBColor":"237,100,0","White":100,"CT":153,"Channel":[0,0,0,100,0]}' not supported by type 'OnOffValue': No enum constant org.openhab.core.library.types.OnOffType.{"POWER":"ON","Dimmer":100,"Color":"000000FF00","HSBColor":"237,100,0","White":100,"CT":153,"Channel":[0,0,0,100,0]}
How did you solve that switch?
I’m sending 100 for ON, 0 for OFF.
Or is there a more elegant way?
