wired/wireless Grove-controlled 220V outlets
A simple, wired outlet is something I find myself making all the time (left side of photo), but I'd rather buy something smaller/safer/nicer than keep making them :)
The [more expensive] wireless product can have the same functionality of a "normal" rf (or ir) controlled outlet, but the remote control would also have a grove socket. If it's necessary to have 2 buttons/pins in order to control such a device (like the a/b buttons in the photo), you can use both yellow and white lines (unorthodox for non-I2C grove modules, but I don't see any reason why not).
