Is anyone aware of a sensor (preferably Zigbee, I think), that will give me an idea of when I need to change my furnace air filter?

I am picturing something that maybe sits on the "clean" side of the filter to measure...pressure? Air quality? I don't know.

If you have your thermostat in home assistant you only need to track the run time and then have it alert you or trigger a sensor when it's been running for a set number of hours.
