SONOFF RF_R2 switch on/off by itself

Hi my SONOFF RF R2 after 2 weeks of corrwct working is switching on off every ten minutes.
Today i left it in ON when i eas not at home e it never switched off. Once at home it begins to switch on off itself.
Changed channel on wifi router and switched off my mobile.

But at the moment it is auto switching on off every 10 minutes.

Someone could help me?

What does dispositivo mean?

Means “device” in italian

This might help…
