stopped working on nov 4.. light was off.
Tried to figure out what was going on .. swapped power supply with other working one i have on dryer circuit... still no power.
opened up and saw it had batteries... removed and it started working..
I always assumed that the batteries were for backup but apparently if you have batteries it uses those and when they die it does not switch to usb 5v power.. So now i have it running with no batteries..
Hopefully this will help others.
