Turn on a switch on startup

ESPHome
1

Hey guys,

I cant find how to turn on a switch on startup.

Im using UART switches to control my tv, but if the device just boots, I need to send a blank switch with a NL and CR to clear the buffer on the TV.

Basically, I just need a switch to turn on when the boot completes on the node.

Cant find it in the docs, any help please ? :slight_smile:

Not sure I quite understand you’re setup, but you should be able to create an automation with a trigger for homeassistant start.

Just write an automation to turn the switch on when HA reboots/starts

  trigger:
    platform: homeassistant
    event: start
  condition:
      condition: template
      value_template: '{{ states.sensor.uptime.state > "0.01" }}'
  action:
    service: switch.turn_on
    entity_id: switch.yourswitch

If you are trying to do this in ESPHome, i would think using these two references should get you there.

First, UART automation, “uart.write…”

Once you know what you need, the “on…” part could be done on boot so that everytime the ESP device reboots the signal is sent:

See if that gets you what you are trying to accomplish!

Good Luck!
