Last night I realized my SmartThings Hub, 2nd Generation; is offline and the red light blinks. I tried to unplug it, and saw the unit was seriously HOT. I took out the batteries and let it cool down till morning. Today I replaced the batteries and plugged it in, and the system was working as usual.
After about 5 hours, I saw the unit was not responsive and the red light was blinking. I unplugged it, and the unit was hot again.
I searched online and couldn’t find the solution for it. I scare if plug it in and the house then it gets on fire. I use this unit flawlessly for two years and never had any issue. Any help or advise would be appreciated.
