How do I get a 'template' switch as a light?

While I’m waiting for my two relay esp01s boards, I’ve started doing the small code for it.
The ‘double relay’ boards uses a template switch like this:

switch:
  - platform: template
    name: '${device_name} Mode change'
    id: relay_led
    turn_on_action:
      - uart.write: [0xA0, 0x02, 0x01, 0xA3]
    turn_off_action:
      - uart.write: [0xA0, 0x02, 0x00, 0xA2]

I tried using this to get it show up as a light:

output:
  - platform: template
    type: binary
    id: light_relay
    turn_on_action:
      - uart.write: [0xA0, 0x02, 0x01, 0xA3]
    turn_off_action:
      - uart.write: [0xA0, 0x02, 0x00, 0xA2]      
light:
  - platform: binary
    id: relay
    name: Floorlamp
    output: light_relay

But I can’t do a turn_on_action or turn_off_action apparently in output?

Yeah it looks like you only have on_write_action for a template output. https://esphome.io/components/output/template.html#output-template-on-write-action

So you will need condition(s) to determine which action to take.

I see, I’ve changed it to this, I hope it works, but I’ll have to see when the boards arrive, at least it’s accepted by the compiler now :smiley:

That looks like it should work.
