Last Christmas I found 2 really small Wifi modules under the tree.
These modules have Wifi (duh), UART, GPIO and are programmable in Lua.
Just think about it - a Door sensor for the price of this module (< EUR 10), a reed switch with magnet and some power... yes, it's possible! (haven't tried it yet though, but I'm going to )
If you like what you've read so far and want to know more, you should also read my recent post about those modules - it can save you some time getting things going

LOL, I read this just a few minutes ago
Re: Very cheap, very small Wifi modules
I was also monitoring the developments based on this device for several weeks, however did not order yet. Lots of other stuff to do.

Re: Very cheap, very small Wifi modules
i backed those
but those are BT and need extra controller

Just an example of what you can do with these modules; MQTT over Wifi for small MCUs like Arduino/Jeenodes etc.
The resulting compiled code size is much smaller than MQTT library + Ethernet library so this leaves more room for the actual code.
The downside is that there's no auto reconnect (yet) which I personally wouldn't want to do without on Wifi.
