So Sense found my HVAC fan for my natural gas furnace. For about 1 week it has been showing it’s usage and was cool to see how long this fan was on for. I was trying to pin point another device and thought it might be a component of the furnace so I was trying to correlate when the HVAC fan was on did this device turn on. Then I noticed that Sense app said my HVAC fan was only on for 2 minutes today. That cant be right it was -5c all day!! I went back into history and about 4 days ago my HVAC fan stopped being detected properly… The power up cycle is captured (like 15 seconds) then it stops detecting it. Any reason it used to detect it properly showing it on for about 2 hours a day, but now it only detects the start up portion of the fan?
