Automation - turn off fan if light is turned off, with "x" minutes delay. But, cancel this automation if is lights turned on again

noger-one · July 8, 2020, 6:32am

Hi all,
I had an automation, that was: When someone turn off light on bathroom, then start the timer, and when this timer was gone, fan in bathroom was turned off. And if the lights was turned on during the timer is on, this timer was stopped. It prevent turn off fan if someone is back again in bathroom. How can i solve this?

Currently i have automation with:
Trigger:

device_id: 594f430136234c5fbeca5294d4d3dbb1
domain: light
entity_id: light.bath_room_ceiling_light
for:
  hours: 0
  minutes: 1
  seconds: 0
platform: device
type: turned_off

and Action:

device_id: b77d17460278430ebf1962c21f641727
domain: light
entity_id: light.bath_room_fan
type: turn_off

Rather than triggering when the light has been off for a minute, trigger as soon as the light goes off but put the delay in the action. See automation #2 in the first example in the docs.

Thank’s for your answer. I got it. But i have still the issue with stop timer, when bathroom light is turned on again.

sparkydave · July 8, 2020, 7:07am

I get around this by using scripts and have one automation first stop the timer script. You could make it such that when the light is turned on, you call script.turn_off for the timer script

PetrolHead · July 8, 2020, 7:37am

Here is an old example of using scripts:
Last detected and time operations

D34DC3N73R · July 8, 2020, 7:39am

I feel like you could do this with wait templates in the action

{{ (as_timestamp(states.sensor.time.last_changed) - as_timestamp(states.light.bath_room_ceiling_light.last_changed)) > 59 }}

and another one

{{ is_state('light.bath_room_ceiling_light', 'off') }}

Assuming you’ve set up time sensors.

noger-one · July 8, 2020, 7:57am

Hi, I don’t have sensor. Automation is depending only by lights is turned on or off. Then wait 1 minute and turn off fan, or stop this automation, if is lights turned on again.

noger-one · July 8, 2020, 7:58am

Hi sparkydale, thank for your reply. I will try it.

Pretty much like Dave I have a script and some fairly complex automation logic, but that’s because : -

My fans all run 1/day on a schedule (stops seldom used fans seizing up)
They run if the house is hot
I can manually switch them on
I can adjust or eliminate the timer
The fans are not to run between set times (night) but this can be overridden with a permissive. And this can turn them on/off if occupied on a transition

But the use case here is simple
Light goes on fan goes on
Light goes off for 1min fan goes off
All done in two very small and neat automations, what’s the problem ?
What have I missed ? I thought I’d read the whole thread but maybe my glasses need changing their prescription ?

noger-one · July 8, 2020, 8:51am

Hi Mutt, the problem is in case, that the lights goes on again, during the automation is fired. I need stop this automation, when the lights goes on again.

sparkydave · July 8, 2020, 8:51am

By the way I left out some stuff in my above post, which relates to how I control them with Xiaomi buttons. They control the above automations and scripts with single clicks, double clicks and long presses.

noger-one · July 8, 2020, 8:54am

Thanks, your code inspire me

Mutt · July 8, 2020, 8:56am

Yeah I get that, but the automation is to switch the fan off ONLY if the light has been off for one minute. If its off for 59 seconds and the light goes back on again, nothing happens

You are basically doing the same as a motion sensor with a light

sparkydave · July 8, 2020, 9:00am

No worries! (also, the odd code for turning the light off slowly is due to those particular lights being z-wave which don’t permit on/off transitions, so that is my pretend transition)

juan11perez · July 8, 2020, 9:33am

try this loop

timer:
bath_room:
  duration: '00:01:00'


- id: xxxxxxxxx
  alias: sssssssss
  initial_state: true
  trigger:
  - platform: state
    entity_id: light.bath_room_ceiling_light
  - platform: event
    event_type: timer.finished
    event_data:
      entity_id: timer.bath_room
  action:
  - service_template: '{%if trigger.platform == "event"%} light.turn_off {%else%} light.turn_on {%endif%}'
    entity_id: light.bath_room_fan
  - condition: template
    value_template: '{{trigger.event_type != "timer.finished"}}'
  - service_template: timer.start
    data_template:
      entity_id: timer.bath_room
      duration: '00:01:00'

sparkydave · July 8, 2020, 10:11am

Later I’ll update my post with the full code for completeness, too hard right now

Mutt · July 8, 2020, 10:28am

Jaun,
Noticed that you used this in your automation, you are aware that this cancels the last_triggered attribute of any such automation on a restart so you need special testing conditions in order for any automation running subsequent to a restart to ‘test and/or ride through’?
Not a problem if you never use last triggered as a condition in automations.

noger-one · July 8, 2020, 10:32am

Hi All,
My working setup is now:
in automation.yaml:

- id: '1594201428926'
  alias: Bath room fan autostop
  description: Autostop bathroom fan for x seconds
  trigger:
  - entity_id: light.bath_room_ceiling_light
    platform: state
    to: 'off'
  condition: []
  action:
  - data: {}
    entity_id: script.1594201213808
    service: homeassistant.turn_on
- id: '1594203376210'
  alias: Bath room cancel timer
  description: ''
  trigger:
  - entity_id: light.bath_room_ceiling_light
    from: 'off'
    platform: state
    to: 'on'
  condition: []
  action:
  - data: {}
    entity_id: script.1594201213808
    service: homeassistant.turn_off

And script.yaml:

'1594201213808':
  alias: Turn off after 30 second
  sequence:
  - delay: 00:00:30
  - device_id: b77d17460278430ebf1962c21f641727
    domain: light
    entity_id: light.bath_room_fan
    type: turn_off

Many thanks for your code and inspiration.
Michal

Mutt, thank you. I didnt know that.
