Summary

  • Ask Google Home/Google Assistant to turn off devices in X minutes (e.g: OK Google, turn off bedroom light in 5 minutes)
  • Cancel current timer (e.g: OK Google, cancel bedroom light timer)
  • New timer will override existing one

How does it work?

  • Voice commands => Google Home/Google Assistant => IFTTT => Call Home Assistant scripts

Setup

HomeAssistant scripts:

  • Main timer script: script to turn devices in X minutes
  • Wrapper script: script to call to main script with logic of cancelling running script.

####### Main timer script
turn_off_bedroom_light_timer:
alias: ‘Timer to turn off bedroom light’
sequence:
- delay: ‘00:{{ time | int }}:00’
- service: light.turn_off
data:
entity_id: light.bedroom_light
####### Wrapper to start turn_off_bedroom_light_timer with logic of cancel existing timer
turn_off_bedroom_light_timer_wrapper:
alias: ‘Timer to turn off bedroom light - wrapper’
sequence:
- service: script.turn_off
data:
entity_id: script.turn_off_bedroom_light_timer
- delay: ‘00:00:01’
- service: script.turn_off_bedroom_light_timer
data_template:
time: ‘{{ time | int }}’

Add IFTTT applets
