Notify if lights is turned on since 2 hours

Configuration
1

Hi,

I’m tryng to implement a notification if I forgot the lights on, i created this, but it’s not triggered:

alias: Lights - Notify if powered on 2 hours
  trigger:
  - entity_id: light.luce_soggiorno, light.luce_terrazzo
    for: 02:00:00
    platform: state
    to: 'on'
  condition: []
  action:
  - data:
      message: Light {{ trigger.entity_id }}  turned on
      title: '*Send a message*'
    service: notify.Michele

Thanks

Thanks,
but it’s not working:

  • event is not triggered
  • if i trig it manually: (MainThread) [homeassistant.helpers.service] Error rendering data template: UndefinedError: ‘trigger’ is undefined

Regards.

What does your config check say ?

You can’t trigger it manually because it has a trigger object in the action, which can’t be parsed if it doesn’t fire ‘normally’

Also, its impossible you have tested this exactly and concluded that it doesn’t work, as it was only posted an hour ago so there’s no way you have waited the required 2 hours for it to trigger.

This means you’ve changed something. Please post EXACTLY what you currently have in your configuration.

You can’t test it that way when the action refers to the Trigger State object (which is undefined when the automation is executed manually). From the documentation for Testing your automation:

Please note that if you click on Trigger of an automation in the frontend, only the action part will be executed by Home Assistant. That means you can’t test your trigger or condition part that way. It also means that if your automation uses some data from triggers, it won’t work properly as well just because trigger is not defined in this scenario.

If you want to test it, temporarily change this (2 hours):

for: '02:00:00'

to a shorter duration like this (2 minutes):

for: '00:02:00'

I’s working now!

I restarted hass and trigger start to work.

Regarding the time, I did another automation with a few seconds, so i can test it.

Thank you very much.

This is something that the alert component does. You might want to check that out. It can also keep sending notifications untill the alert is dismissed.

Glad to hear it works now.
