Fan running for almost 8 hours

The thermostat detail shows that my fan was running for almost 8 hours this morning, but it is turned off. It also shows that the fan is running whenever the heat is on, but I have a boiler. The fan only runs when the AC is running.

Yeah, this sounds like a bug. I’ll have to check, but I believe beestat marks the fan as “on” any time heat or cool is on assuming you have forced air. I suppose that assumption is invalid for radiant-heat solutions. Good find!

I have a whole house dehumidifier and am seeing the same bug. In Beestat it shows the fan running the entire time the dehumidifier is on. The Ecobee graph doesn’t show this-- only has it running (correctly) when cooling is active.
