I read it here:
And the device that I purchased is this one: (which i assume that’s what the v2 model is)

In terms, of 110v vs 220v, in my experience there is a ton of devices that are multi-voltage, but labelled 110v only – such as some of the Aeotec devices, all the Wemo smart plugs (I have like 10 of them - standard and energy-reading ones) and most Samsung TVs actually. Of course many are truly only 110v. In terms of risks, my thinking is that if this plug is truly 110 only, then it will pop/burn up pretty much immediately - as this is what usually happens when I plug 110v device in 220v. If it’s stays neutral to the touch, working fine for weeks on end, i would assume it’s a compatible 110-220v unit?
