Tasmota RGB convert to Hex

Configuration
1

I’ve been searching the forums and documentation for a couple hours but cannot find a solution. Tasmota requires (at least to the best of my knowledge) any solid color change to be submitted in HEX format but is appears HA requires (xxx,xxx,xxx) format. For reference I have a ws2812 strip connected to a wemos D1 mini. I can change schemes, change dimmer levels etc from within HA I just cannot change the color. If I manually use the Tasmota “console” I can change the color.

In short, is there a module or script or anything that can help send colors in HEX.

Even if I was able to create a static color list of say a dozen colors that would be fine. Just like the “effects_list” option a color_list would do just fine.

thanks

bump. anyone!

rgb_command_template: "{{ ‘%02x%02x%02x’ | format(blue, green, red)}}"

Add that into your light mqtt config and try it. Works for me with tasmota on a wemos d1 mini ws2813 strip.

Thanks. I stumbled across that as well. PS: my light buld in the UI changes color when I use the color picker so the data is there somewhere. The frustrating part is that was added to HA more than 2 weeks ago and I saw this command 2 weeks ago. Not bashing HA, but the documentation on this is absolutely horrible…

“rgb_command_template (Optional): Defines a template to compose message which will be sent to rgb_command_topic. Available variables: red, green and blue.”

Maybe I just don’t understand templates, but how was I supposed to understand I needed '%02x%02x%02x’ with that description.

Generally speaking HA documentation is really good. in fact, much better than most open-source software, but if someone sees this, the documentation is just too generic, too simple. We need better example of how to implement moderately complex stuff. Just my 3 cents. thanks again.

Would you mind sharing your config? I’ve been trying to figure this out for days

Thank you for that you saved me some major headaches. I was also wondering how you exposed the color, dimmer and scheme controls in HA?

Awesome. I finally got some time to sit down and get this working. Thanks for the help guys.

neither of these configuration snippets are working for me, impossible to select a color from the picker.
On, Off & Dimmer work fine though.
There’s many many errors in the log.
Can some one please confirm ??

11

It works perfectly for me I don’t see any errors regarding the lights.

@Beef-well would you mind pasting yr relevant config for the h801 please? Also, confirm you can pick a color from the rgb wheel, you seem to say that On, Off & Dimmer work - but you do not mention the color picker ?

13

I used the config that Oriolism posted above. Sounds like your RGB state topic isn’t quite right.

14

I updated Tasmota to 5.12 (from 5.11.1), now the color picker works.
There is still a bucketload of errors in the home assistant log, so definately something is still off.

Would some one please have a look at their log when selecting colors ?

15

I get
Error doing job: Exception in callback <function async_subscribe.<locals>.async_mqtt_topic_subscriber at 0x7f93c3735c80> 11:13 AM components/light/mqtt.py (ERROR)
when I select a color, but everything still works.

that’s only a tiny part of what is really added to the log :
