hi,
I’m trying to control in HA an esphome ledstrip via a button: yet I have to turn on, select the effect and turn it off always going to submenus of the light effects. but really I only want a single button to toggle the effect on and off.
in esphome I yet only able to make two separate button: one to enable the effect and one on to turn on/off the light. unfortunately If I try to set the effect in the “on” part of the on/off it doesn’t work…

- platform: template
    name: my_random_button
    on_press:
       then:
        - if:
            condition:
              light.is_off: DC_Neo
            then:
              - light.turn_on:
                  id: DC_Neo
                  brightness: 0.5
                  effect: Rainbow Effect With Custom Values

  - platform: template
    name: my_On-Off_button
    on_press:      
      then:
        - if:
            condition:
              light.is_off: DC_Neo
            then:
              - light.turn_on:
                  id: DC_Neo
                  brightness: 0.5
                  effect: Rainbow Effect With Custom Values
        - if:
            condition:
              light.is_on: DC_Neo
            then:
              - light.turn_off: DC_Neo

Also with lambda didn’t work: cannot find the command to set the brightness.
does anyone know why or how to do it? I know probably with an automation but still figuring out how to do it…

now I got a working solution, maybe overengineered, adding a binary_sensor used as a status to set and read…
so now I have two button and a sensor to just use a single button!
as usual if I try to incorporate the action of the second in the first doesn’t work…
also if can chose to not show them in the dashborad, I probably think there’s a better and simpler way, which I don’t know now…
