Help - count the number of times an entity change to a certain value (like ON or OFF)

Configuration
1

I have an entity that allows me to turn a light on and off. I want to count the number of times the lamp is turned ON. how can i get this done the easiest way?
I would prefer to see the number of times per day / week and month.

Thanks!

Hello,

You can use the History Stats sensor for that purpose.
The exemple needs only to adjust to get the count instead of time, like so:

sensor:
  - platform: history_stats
    name: Lamp ON today
    entity_id: light.my_lamp
    state: "on"
    type: count
    start: "{{ now().replace(hour=0, minute=0, second=0) }}"
    end: "{{ now() }}"

EDIT: You can use the given exemples in the link to adjust for time periods (current month, current week, …)

That would count the time when it is on, not the number of switches from off>on which I believe is what the OP asks for.
My 2 cts…use an automation that triggers on off>on and update a helper (input_number) via service: input_number.increment

It is counting one “on” when it comes from “off”.
I’ll do it in my config to check if it is working the way it should.

Then I might be mistaken but I have a history stats setup for when my son’s PC is ‘on’ and it counts time…not the switch off>on.
edit:

  - platform: history_stats
    name: PC Game on
    entity_id: binary_sensor.desktop_gaming_power_status
    state: "on"
    type: time
    start: "{{ now().replace(hour=0, minute=0, second=0) }}"
    end: "{{ now() }}"

That is after turning the switch on/off 4 times, as expected :slight_smile:
