Here is one of several examples. I have a flow that will start the laundry’s exhaust fan when the humidity is higher than 79% there. Then there is a timer that will turn it off after 20 minutes (enough time to replace the air in the room).
However, if Homey goes offline 15 minutes after the flow started, and goes back online 10 minutes after that, it missed the 20min mark for turning off the fan. This has happened a couple of times already, and the fan was on for hours before we noticed it.
