Use history_stats in automation?

Configuration
1

Hi,

I have a history_stats sensor that counts how long another device has been in a certain state. It works fine but Id like to use that value in an automation (ie if value > 2 then) but I cant find how to reference the sensor.

Any ideas?

You’ll want to loo a the numeric_state platform - here’s an example:

######################################################################
# Notify if Circulation Pump has been on for long
######################################################################
- alias: CPump on too long
  trigger:
    platform: numeric_state
    entity_id: sensor.cpump_on_last_20min
    above: '55.5'
  action:
    - service: notify.mypushbullet
      data_template:
        title: "HASS says:"
        message: 'CPump has been on for too long @{{now().strftime("%H:%M")}}h!'

Cheers,

The trick is getting the data into the numeric sensor. The history_stats sensor accurately displays the on-time of my device but i dont know how to use it in a template. I could user a timer and track the usage time myself but it seems silly when the history_stats component does this already.

Maybe you need to show what you have defined so far - it’s a little abstract at the moment.

I have a history_stats sensor. I want to know when the value exceeds 2. I have no idea how to reference it.

  - platform: history_stats
    name: XBOX Monitor
    entity_id: sensor.xxxxxxx
    state: 'Online'
    type: time
    start: '{{ now().replace(hour=0).replace(minute=0).replace(second=0) }}'
    end: '{{ now() }}'

What are the attributes of the sensor?

Look in the developer tool states menu <> (lower left).

What @tom_l says plus specifically what is sys in the state column for your sensor.

Shouldn’t it just show up in as “sensor.xbox_monitor”? If so, that’s how you reference it.
