Trigger automation based on date from template

[matejdro (Matej Drobnič)]

Hello,

Is there any way to dynamically trigger automation based on date from template?

More specifically, I’m using Google Calendar integration. Calendar sensor has start_time attribute. I want my automation to trigger 10 minutes before the start time.

Ideally, I would want some automation to trigger whenever calendar sensor updates and schedule another automation for exactly 10 minutes before the start time. But I cannot find a good way to do this. At the moment I’m just updating the automation every 10 minutes and filtering it with condition template which is a bit wasteful.

Is there a better way to do this?

automation on your sensors’s state change

@matejdro

and schedule another automation for exactly 10 minutes before the start time

in action: get the start time, decrease it by 10 mins, set a timer (and don’t forget to create an automation that should run when the timer expires)

Timer actually looks like what I want. Thanks!
