MQTT configuration for SHCB is not fully compatible with HA MQTT integration. At least I didn't manage to create a properly working configuration.

Hello @bieniu,

thanks for the information. Is there a way to implement the following code? This works for me, but I would have preferred the device to be detected automatically by the script.

I'll check that, thanks.

I tested your configuration a few days ago and it works but unfortunately I don't have time to implement it in the script. Maybe at the weekend...

[bieniu]

I see a big problem with your configuration. If you set a color for the light and then switch back to white mode, the light icon still shows the last used color. So far I have no idea how to get around this.

[tc-maxx]

I tried to add switches to filter the temperature and RGB values in the response in a way that HA understands. But unfortunately I don't know how HA wants the value for the temperature.

      color_temp_template: "{% if value_json.ison and value_json.mode == 'white' %} {{ 1000000 | multiply(1/(value_json.temp | float)) | round(0) }} {% else %} 0 {% endif %}"
      red_template: "{% if value_json.ison and value_json.mode == 'color' %} {{value_json.red}} {% else %} 0 {% endif %}"
      green_template: "{% if value_json.ison and value_json.mode == 'color' %} {{value_json.green}} {% else %} 0 {% endif %}"
      blue_template: "{% if value_json.ison and value_json.mode == 'color' %} {{value_json.blue}} {% else %} 0 {% endif %}"

But with this adjustment, when switching to white mode, the light icon will be white.

[bieniu]

Yup, I tried exatly the same yesterday. I think we should calculate the correct RGB values in white mode.

[tc-maxx]

Have you ever used this somewhere, I'd like to take a look?

[bieniu]

No, I haven't used such calculations anywhere, I suspect that we will find something like that in the MQTT integration code.

Stale issue message

[Xinayder]

I was messing around with this, trying to implement it by myself and found out that the template schema doesn't support color modes: https://www.home-assistant.io/integrations/light.mqtt/#comparison-of-light-mqtt-schemas

So, I used the work from the OP and finally implemented a light that works with my Shelly Duo RGBW GU10. The trick was to pass none to red_template, green_template and blue_template fields if mode is set to white, so Lovelace can correctly display the white temperature of the lamp if it's not using RGB.

schema: template
qos: '0'
red_template: '{%if value_json.mode == "color"%}{{value_json.red}}{%else%}{{ none }}{%endif%}'
green_template: >-
  {%if value_json.mode == "color"%}{{value_json.green}}{%else%}{{ none
  }}{%endif%}
blue_template: >-
  {%if value_json.mode == "color"%}{{value_json.blue}}{%else%}{{ none
  }}{%endif%}
