I bought a ThermoCube to control heat thingies in my coop. I've been having trouble with it. When I looked at reviews for them on Amazon, I found a number of "they're great" and a number of "It worked for a while then quit" or "never worked" reviews.
I powered mine at first with an ungrounded extension cord, and it worked for a few days then quit. I plugged it into the GFI outlet in my shop where the temp was below freezing, and verified with a nightlight that it was still working. Then I warmed it up inside and tried it in a non-GFI outlet on the back porch, and again verified that it works. So I returned it to service in the coop, this time with a grounded cord but not plugged into a GFI. It worked for a while before nightfall, but the next morning it was not doing it's thing.
Do these things require a GFI outlet to switch properly? Has anyone else had trouble with them? I love the idea of the thermocube, but I'm not willing to trust the thing right now.

Hens go broody when you don’t want them to… and won’t go broody when you do.
