Air Filter Countdown

This project creates a sensor that tracks when the HVAC filter is changed, and sends an alert when it needs to be changed 90 days later.

I’m using a Wyze sense door sensor to trigger the automation when the filter cover is opened, but any door sensor can be used.

This is my first post, and my first time posting a project on GitHub, so I apologize for my sloppiness! I have been using Home Assistant for about 6-8 months, but I have no coding background.

Utilizing bits of your code I came up with this card setup instead of doing a picture entity:

Since I don’t have a reed switch on my filter door I just use a input_bool and butonized it.

Code:

cards:
  - entity: input_datetime.air_filter_date_installed
    type: entity
  - cards:
      - entity: sensor.air_filter_life_remaining
        type: entity
      - entity: input_boolean.filter_changed
        hold_action:
          action: more-info
        show_icon: true
        show_name: true
        tap_action:
          action: toggle
        type: button
    type: horizontal-stack
type: vertical-stack

Thanks for the great idea!

The only reason I am able to make anything happen in HA is because of this amazing community. Just trying to pay it forward when I can!
