Im ordering a couple of these to have a play with. Someone somewhere posted they have an esp8266 in them so might be able to replace their dire software with something automatable.
Also there is this one which looks interesting, 5 outputs. I think I already ordered one of these and it got put into a box when I was doing a cleanup so not reordering till I have had a sort out of things I am meaning to finish off.
Anyone else done anything fun with these cheap wifi modules?
