This is good, thank you.
I got few sonoff basic in somewhere, this can be a good for this.

If you can add the function to start charging under a configureable battery percentage i will actually use this.

+1, I will very appreciate start of charging when phone battery is 10% below configured treshold.

can work for laptop battery ?

Hello, @vorion

In order not to create a copy of your blueprint, maybe you can change the current one and add the requested โ€œturn onโ€ feature.
You have just to:

  1. define another input named discharged_percent similar with charged_percent and an associated variable
  2. remove the condition block

condition:
condition: template
value_template: โ€˜{{ (states(phone_battery)|int) >= (charged_percent|int) }}โ€™

  1. replace the action block as following:
action:
- choose:
  - conditions:
    - condition: template
      value_template: '{{ (states(phone_battery)|int) >= (charged_percent|int) }}'
    sequence:
    - service: switch.turn_off
      data: {}
      entity_id: !input 'switch'
  - conditions:
    - condition: template
      value_template: '{{ (states(phone_battery)|int) <= (discharged_percent|int) }}'
    sequence:
    - service: switch.turn_on
      data: {}
      entity_id: !input 'switch'
  default: []

Haha, nice.
I was thinking of this too, but then with a slightly different approach.
My idea was/is to store the charging time to full charge in a helper and set a โ€œwake-up timeโ€, so it would start charging โ€œjust in timeโ€ to be fully charged at the moment I get out of bed. Off course it should always start charging when my phone hits 1%.

Nice work though!

Is it possible to fork/change this blueprint to individual needs?

Iยดm thinking of just notifying when threshold is reached instead of switching off the power plug - because on that power plug more than one device is charged at the same time.

Great work! I added an additional feature though. If Iโ€™m at work charging my phone, I donโ€™t want my plug turning off since something else might be plugged in at that time. So to solve this, I added the condition that I should be home for the plug to turn off.

would love to see this added, currently I have to turn the switch back on to charge my phone which is not very intuitive.

I think I have this working pretty reliably in a blueprint/automation. However, it seems my phone, a OnePlus 6t, is going several % over and under before HA knows to turn off/on the switch/plug. Iโ€™ve read the polling for updating entities is about 30 seconds. However, this is several minutes, sometimes 10 minutes before it updates and either starts charging or stops. Any thoughts on a more frequent update of a battery level entity?

Same issue especially with my iDevices: they fall in deep sleep on WiFi and HA sensors are not updated at all or after hours. Canโ€˜t really use that automationโ€ฆ -.-

Hi, Iโ€™m new here and just learning.
I have tried to do as you have said, but the extra option for turning on is not showing up in HA.
Can you share Full Blueprint please, just getting my head around this coding, then i can compare the 2 and see where i have gone wrong

Hi there and happy 2021!

See the improved blueprint here: Stop/start charging based on battery level when home .

Update: meanwhile because of this for all my charging stations I use smart plugs with power measurement and another blueprint. That way e. g. my iPhone can sleep with flight mode active during the night and the smart plug stops charging automatically. Works great for months now.

Thanks! This works for me (unfortunately only with the Shortcuts App in IOS (If I close the HA App the sensors are not updating)

But I have a question. If the iPhone is charged at 85% the power goes off, I unplugged the iPhone and then the power plug should be active again or not?!
