I had trouble with my internet connection and i was away from my home for 3 month. When i come back i had to fix my internet connection first. Then i saw that my google home was like reset to factory, and sonoff was completely off even if they where connected to the plug. Now the problem are:
Not working by touching the "button", led is off, when i try to reset the led is not blinking but i see some sounds.
Not working by pressing the button. led is turned on and off with a delay of about 1,5 minutes.
It is very strange i've never had this kind of problems. I'm unable to reset them because they had a really unexpected behavior.
