Pretty simple bug, I have 2 of these and both of them exhibit this problem. After a day or so of continuously being on (sometimes after a few hours), the plug cuts power. The green LED on the front still indicates as though it is switched on (the "switched on" LED, not the WiFi connected LED). I haven't set any schedules and the power limit is "off". Both running the 1.02b5 firmware (latest).
Super annoying.
