Example: Timed Switches

palitu · November 27, 2016, 3:50am

I have a couple of switches that i wanted to only allow to run a maximum amount of time, which is configurable by an input_slider. There have been a few times that i have forgotten to turn of my retic when triggering it manually.

This solves all of those problems. It is based around the example automation for turning a light on for 10 minutes.

It performs two functions:

1.Automation Trigger: Switch Turns On
2. Script On: Delay for x minutes

1.Automation Trigger: Switch Turns Off
2. Script Off: turn off delay script (essentially resets the timer if you manually turn off the switch)

Automations:

automation:
- alias: "Pool: Automatically turn off"
  trigger:
    - platform: state
      entity_id: switch.pool
      to: 'on'
  action:
    - service: script.turn_on
      entity_id: script.pool_timer
- alias: "Pool: reset timer"
  trigger:
    - platform: state
      entity_id: switch.pool
      to: 'off'
  action:
    - service: script.turn_off
      entity_id: script.pool_timer

Scripts:

script:
  pool_timer:
    alias: "Pool Timer"
    sequence:
      - delay: '00:{{ states.input_slider.pool_run_time.state | int }}:00'
      - service: homeassistant.turn_off
        data:
          entity_id: switch.pool

Input Sliders:

input_slider:
  pool_run_time:
    name: Pool Run Time
    initial: 10
    min: 1
    max: 60
    step: 1

Groups

group:
  backyard:
    - switch.pool
    - input_slider.pool_run_time

That’s awesome. I’m setting that up to turn off bedroom lights when they’re left on as well as for the pool pump.

palitu · June 9, 2017, 2:09am

how’d it go with your lights/bore?

Beef-well · June 14, 2017, 7:02pm

It works great. I’ve got a Sonoff POW in a weatherproof enclosure and have automations setup to turn on the pump when if it rains or if it’s windy and then turn off based on what I have the slider set to. Another automation set to turn all of the weather automations off it reaches a daily 9.5 KWh threshhold. I might switch that to a historic statistic sensor and just base it on time rather than power usage. So far it’s been working out very well. Thanks for the inspiration.

Hi Beef-well,

In your example you show a delay in the HH:MM:SS format and the input slider goes to a max of 240. How does HA handle when the MM part is 60 or more. Normally that would need to equate to 01:00:00 which would the expected way. Any idea, does your setup simply work?

Thanks
Erwin

Hi @palitu @Beef-well

I’m trying to base on your example to use slider input for garden watering.
Configuration:

switch:
  - platform: rpi_gpio
    name: "Watering"
    ports:
      5: Water trees
      6: Water lawn
input_number:
  water_slider:
    name: Watering Run Time
    initial: 20
    min: 1
    max: 90
    step: 1

Automation:

- id: turn_off_lawn_water
  alias: Turn off garden watering
  trigger:
  - entity_id: switch.water_lawn
    platform: state
    to: 'on'
  action:
  - service: script.turn_on
    entity_id: script.water_timer

- id: reset_water_timer
  alias: Reset water timer
  trigger:
  - platform: state
    entity_id: switch.water_lawn
    to: 'off'
  action:
  - service: script.turn_off
    entity_id: script.water_timer

Script:

  water_timer:
    alias: "Watering Timer"
    sequence:
      - delay: '00:{{ states.input_slider.water_slider.state | int }}:00'
      - service: homeassistant.turn_off
        data:
          entity_id: switch.water_lawn

My problem is: HomeAss throws error on template parsing {{ states.input_slider.water_slider.state | int }}:

2018-03-17 22:19:54 ERROR (MainThread) [homeassistant.core] Error executing service <ServiceCall script.water_timer>

During handling of the above exception, another exception occurred:

While i run the script with static number of minutes it works OK.
Is there workaround? Any other way to read a value from slider?

Ivy_Growing · March 17, 2018, 8:36pm

Hi @elonden,

In this thread there is sophisticated script which derives correct time.
If templates are working for you, this should be good solution.

For me templates don’t work (HA version 0.63.2)

edif30 · March 18, 2018, 12:30am

@Beef-well How many watts/amps does that pump pull? Are you on a 15a or 20a breaker? And what is the rating of the Sonoff POW?

Beef-well · March 18, 2018, 2:27pm

The pump draws 11 amps max. It’s on a 15 amp circuit along with a couple of receptacles and a light or 2. The sOnOff POW is rated for 15 amps.

edif30 · March 18, 2018, 11:24pm

ah ok thanks. I’m in search for a 20amp switch and tough to come by. I def don’t want to go higher in the event of overdraw.

Beef-well · March 19, 2018, 1:38pm

You could make your own. I’ve been playing with ESP8266s and runningTasmota on it you could get a more robust relay and do what you’re wanting to do. This is a WS2812 LED Strip controller I put together in a little waterproof box running Tasmota.

It could pretty easily be set up to control a 20 or 25 amp relay.

Beef-well · March 19, 2018, 2:09pm

Looks like your script is still using input_slider. input_slider has been changed to input_number.
See if that helps. I haven’t converted mine to the new version yet. I’ll share my config once I get it updated.

Here is the updated config for my bedroom light timer

        data:
          entity_id: switch.bed_room

Hi, would you mind to post a screenshot of the automation editor you configured?
I am messing with the syntax and home assitant is complaining about the code itself, when I copy/paste it.

Thx
Andreas

i got it to work , thanks to you @palitu , i had these water pumps that needed to work on timers as per my input…this sorted it nicely.

palitu · May 17, 2018, 5:20am

Cool!

i use them a bit

Ranur · March 4, 2019, 3:42pm

Thanks @Beef-well! Used it for a snooze function to turn off my bedroom tv. Works flawlessly!
