Trying to have relay on after a boot?

ESPHome
1

I’ve used @frenck’s very advanced esp config to get my Sonoff Pow 2.
I have it mostly where I want, there are two minor issues left.
I would like it be turned on when it boots.
I have the blue led to turn on when it uses power, I would rather have it reflect the ‘running’ sensor.

But I can’t get it to be on when it boots, and so far the blue LED indicates if it uses more than 4w.

Try

 - platform: gpio
   id: relay
   pin: GPIO12
   restore_mode: ALWAYS_ON

Thankyou, that is much neater than what I did.
I actually just found out that my method works as well, the problem is that it isn’t shown correctly in HA after the boot??? It is shown as being off, where it actually is on.
If I manually turn it on in HA, I can turn it off after that.
Ok, so the problem is not that it isn’t on, the problem is that it doesn’t report the correct state after the boot.

I see

problem is ESPHome is reporting your switch state which is optimistic template switch, not the gpio which seems to be what you want.

Unfortunately switch does not have restore_mode
but since you want it to boot powered “on” you can try this:


  on_boot:
    then:
      - switch.turn_on: relay
      - switch.template.publish:
          id: fakebutton
          state: ON

That worked perfectly, thankyou!
I tried publishing to the switch, but that didn’t work :smile:
