When i trigger a relay on.. cant work out how to delay 15 secs then turn off

Configuration
1

Hi ya all.

so im quite new to home assistant and I am having issues with a relay and door lock.

ok so i can control the door lock via mqtt, i can manually turn it on and off. i am now trying to configure HA to turn the relay off after 15 seconds.

i am using a esp-01 to control a relay that runs to a door latch.

the entity is switch.shed_door

i just cant work the code out at all. I could change the arduino code on the esp but down the track its easier to mod the HA config rather than the arduino code.

automation:

  • alias: Turn off relay after a delay
    trigger:
    platform: state
    entity_id:switch.shed_door
    to: ‘off’
    for:
    seconds: 15
    action:
    service: homeassistant.turn_off
    entity_id: switch.shed_door

seems not to work. i guess i got it wrong somewhere :stuck_out_tongue:

any assistance would be great

thanks in advance :slight_smile:

In your automation, nothing will happen. That’s because you are waiting 15 seconds after the switch.shed_door is turned OFF, then telling HA to turn OFF the same switch.

Assuming that something else is turning ON the switch, change your trigger to ON instead of OFF.

thanks :slight_smile: yeah when i manually flip the switch on my phone its ment to flip the relay for 15 secs then turn it back off. I built a 12v - 3.3 to control the esp-01 and i just dont wana get the voltage reg to hot (only blown one cap so far lol. forgot to swap out a 10v cap for a 16 when i changed incoming psu)

You need another automation to reset the relay. I have one here
