This project uses standard HA elements (Helpers, Automations, Lovelace Cards) to track HVAC running time and trigger a filter clean reminder card indication & notification. [Purpose was to keep it simple & avoid using addons or custom integrations to minimise being exposed to breaking changes].
Setup [Working with HA Core 2025.1.2]
- An existing sensor of HVAC status running or not (i.e. on/off) used to control the runtime timer helper. [e.g. a Threshhold Helper “Trigger Aircon Running” controlled by a minimum AirCon power trigger point, or see optional config.yaml code below to create a sensor from the Daikin HA integration].
- A Timer Helper used in a Tile card to track HVAC runtime e.g. “Daikin Filter Remaining”. [Timer Duration is setup as per desired AirCon running time filter clean interval (e.g. 90 hours), select ‘restore state’ so that timer survives HA restarts. Note that Timer Helpers only count time down i.e. time remaining].
- An Input Boolean Helper used in a Tile card to indicate when filter clean is due e.g. “Daikin Filter Due”
- An Input Button Helper used in a Button card to Reset the timer e.g. “Daikin Filter Reset”
Automation:
This controls the timer & cards and includes a notification when filter is due. [There is also an option to manually adjust the Timer remaining Duration, see notes in Automation].

Aircon Filter timer using AC runtime.
*Option 5 disabled Action: use to manually decrease/ increase the timer by a
desired unit of time. Check timer entities are correct, enable Action, edit
Duration [e.g. edit Duration to -30:00:00 to decrease current timer by 30
hours] & manually Run Action.
