  • how do you typically notice the filter needs to be changed now? does it:

    • draw more power than usual? wattage sensor
    • give some alert like a “change filter” light? esp32
    • need changing after a certain time/usage amount? power consumption sensor
    • need changing every X days? you might just need a calendar alert

    of course the mega nerd approach would be to put a particulate sensor in the duct like a PMS7003 that measures PM10 particles like dust, strap on an esp32 and set some alerts using your favourite monitoring tool.
