Within automations.yaml I have placed this code:
- alias: Fan trigger: platform: state entity_id: light.bathroom to: 'off' action: service: switch.turn_on entity_id: switch.sonoff218
When the state of the light in the batroom (Philips Hue) changes to OFF the fan (Sonoff) starts running. So far so good but I did not succeed adding a timer function so the fan stops after a certain time.
Can someone help me to add this timer function?
