Very nice! May i propose that you add mobile phone notification of some kind, in case of emergency, like GCM for Android phones?

How stupid of me. But of course it would be on the official mysensors site 😀😂😂😂

I don't know how to help you with that module but why don't you try with tft lcd with touch capability?

This module looks very good. Where can I buy these? Does it sells as soldered module or (can I buy) only PCB?

Thank you! This is an AWESOME project. What comes next? Light switch with touch screen? That will be even more awesome project :D
