@dondch ,

Looks like there is one more 'glitch', the status of channel 1 and 2 are not updated on HA when operated by the manual switch :-/
Will try to fix it (or maybe you already did ??)

Finally had the time to fix the 'glitch' that the status of channel 1 and 2 are not updated on HA when operated by the manual switch by using value_template See also HA documentation https://www.home-assistant.io/integrations/switch.mqtt/

Just replace

    state_topic: "dualdimmer/stat/POWER1"
by
    state_topic: "dualdimmer/stat/RESULT"
    value_template: '{{ value_json["POWER1"] }}'

And ofc the same for POWER2:

light:

- platform: mqtt
  name: "dualdimmer_SW1"
  state_topic: "dualdimmer/stat/RESULT"
  value_template: '{{ value_json["POWER1"] }}'
  command_topic: "dualdimmer/cmnd/POWER1"
  availability_topic: "dualdimmer/tele/LWT"
  brightness_state_topic: "dualdimmer/stat/RESULT"
  brightness_command_topic: "dualdimmer/cmnd/Channel1"
  brightness_scale: 100
  brightness_value_template: >
  {% if value_json.Channel1 is defined %}
  {{ value_json.Channel1 }}
  {% else %}
  {% if state_attr('light.dualdimmer_SW1','brightness') == none %}
  0
  {% else %}
  {{ state_attr('light.dualdimmer_SW1','brightness') / 255 * 100 }}
  {% endif %}
  {% endif %}
  qos: 1
  payload_on: "ON"
  payload_off: "OFF"
  payload_available: "Online"
  payload_not_available: "Offline"
  retain: false

Great job, the devices (I have multiple) works fine on tasmota consolle. I am using node-red instead of HA, I can switch the lights on and off but can't control dimmers, can you please tell me the MQTT command (or the console command) to dim Channel1 ans channel2? thanks!

Hmm..I also use node red (within HA), but not with MQTT.
(Or did I misunderstand, and you use MQTT only and no HA at all??)

In case you do use HA, I use a 'fixed' brightness here, I'm sure you'll find a way to adapt it.

I also tinkered a while ago with a softstarter

Hello everyone!!!! I did everything according instruction.I have entered the script, the template and activated "Setoption68 1". In web interface I see all correct. Toggle 1 and 2 are working but my lamps not light(((((( What is the problem???

Sorry for this moment lamp lights everytime and dont turn off. In console I see turn on and off process

This thread is probably dead but I will try.
I've successfully flashed LM1 chip with script enabled firmware. I've pasted the script and enabled Setoption 1. Everything looks ok in Tasmota. I can see two toggles for both channels, both sliders for dimming and two counters.
My problem - my lamps are always off despite of the status in tasmota. I've tried checking corresponding channels with multimeter and one of them reports ~10V when the lamp is on or off, and the other one is always 0. Using push button also doesn't work. If I push the button toggle status doesn't change and only the counter increases.
I've tried script in this thread and script available here - https://gist.github.com/maxela/64af0e0471aa59c1550b05d8c0d79802
Maybe I did something wrong? Any help would be appreciated...
Thank you!

There’s not much happening in this thread, but I get notified and usually I try to help.

Which device and which version of the tasmota firmware are you using?

Hi, @maxela, thanks for a quick reply!

At first glance it looks like I'm using the same two channel dimmer that is displayed in this thread with LM1 chip but my version might be a bit different. I will attach a photo of the insides when I get back home from work.
I'm not 100% sure but I believe it was 9.5.

Just for info, i moved to esphome with this 2ch dimmer unit, it works a lot smoother.
