Wake up times can vary, and I "need" a way to sync my towel heater with this. Ultimately I would write a program which scan my alarm clock on my phone, create events on my calendar accordingly so heater is synced. And, more, if for any reason, I don't wake up, my system would turn off heater. I monitor light, temp, humidity, power consumption, publish them to Cosm, all of these produce "wake up" patterns when reading graphs. If this pattern wouldn't appear, then it would be turned off. > > RF over four stories is a long way... It's going through wall the better, > the lower the frequency is.

As for power line carrier, there's no such power line on my cellar. I was hoping to find a way to communicate between floors, using an ultra low consumption setup on batteries...
