Is anyone getting the message "Your Fetch box is hot"?
It was fine over summer and since the last update I'm getting this when the room is only 20c.
I reckon the best bet would be getting in touch with Tech Support as they'd be able to sort out a replacement box if they can't fix it from their end. Definitely an odd thing to happen with an update :/
Just called tech support and they have advised that this is a known issue introduced in the one of the last updates. They have issued a new firmware update and performing a hard reset via the options menu should initiate the new firmware download and fix the problem.
hopefully this will work.
