Has anyone ever done something like this? They say you can hook this up to a phone/tablet/PC via WiFi by adding a module and battery. So I imagine one could integrate it with ST somehow.
My plan would be to place this in one of my air vents and have it constantly measure airflow. That way, instead of checking the filter all the time, it would notify me that I need to change the filter once the airflow gets below a certain point.
Interesting.
I am on a 3 month schedule. Change them faithfully. However, I don’t know why sometimes they are dirtier than other times. Actually, never even thought about it until now…
Hey Google…

Did you give this a try?
