Refrigerator Filter Sensors

[shwarnock]

My LG refrigerator has an air filter and water filter sensor that can let me know when they need to be replaced. These don't seem to be integrated into HA. I would love to have sensors for these two filters so I can run some automations when they need to be changed. Basically, send some phone notifications and add the filters to my shopping list.

I second this feature request.

Any traction on this? If there is anything I can do to help lmk

The water filter used month is available under the refrigerator sensor:

I do not have an air filter so cannot comment on that. The recommendation (in case of my fridge) is to change the filter every 6 months, so I have an automation to send a push message every day to my phone if the sensor value is >= 6.

My fridge has an air filter and currently has a value of fresh_air_filter: Looks Good I just replaced it so I'm not sure what the values are as time goes on.

This would be a helpful feature. I had to wait six months for the air filter to expire first before I could see the attribute values in order to automate it. Sharing the template binary sensors I made here:

template:
  - binary_sensor:

      - name: Fridge Air Filter
        device_class: problem
        unique_id: fridge_air_filter
        state: >-
          {{ is_state_attr('sensor.refrigerator', 'fresh_air_filter', 'Replace Filter') }}
        availability: >
          {{ states('sensor.refrigerator') not in ['unknown', 'unavailable', 'off'] }}


      - name: Fridge Water Filter
        device_class: problem
        unique_id: fridge_water_filter
        state: >-
          {{ state_attr('sensor.refrigerator', 'water_filter_used_month') | is_number and state_attr('sensor.refrigerator', 'water_filter_used_month') >= '6' }}
        availability: >
          {{ states('sensor.refrigerator') not in ['unknown', 'unavailable', 'off'] }}

Thanks for the info! I was able to get this setup and I believe it is working properly. I won't really know for sure until one of the filters trigger to a 'needs replacement state' but I will see when the time comes
