I might look into Neo, @Odechr, but preferably from another supplier than AliExpress 
I have bought battery operated sensors from AliExpress, but I’ve poor experience with electronics connected to the power grid. I’d rather buy them locally.
The plugs I am buying this time is only for power monitoring, and would never be used to toggle power on and off (eg. freezer, dishwasher etc.). Therefore I think WiFi is good enough, as it is not critical if I loose network.
