If these aren't deemed home automation'y enough please remove, but I have a few sets of the BT Vision type Comtrend powerline adapters for sale, one set without the 13 amp passthrough sockets, and a couple of sets with 13 amp sockets on the front, if anyone is after any to build / extend a powerline network. Particularly useful for getting a network connection out to an outbuilding / shed, or for buildings with thick walls!
