Re: I'm full of not surprise
I bought some SonOff 2.4gHz mains switches. On playing with them it was found they needed a smartphone app and Cloud connection. Fortunately the V1 and V2 models' firmware could be flashed with EspEasy to be Arduino controlled via a dedicated intranet in the house. The V3 model appears to be less amenable to this solution. Its new wifi daughter-board blocks access to the position to which you would solder the flashing connector.
