I agree power is an issue in any event with any RF device though some are
worse than others. I was assuming that anything would have to be hooked up to
the mains as I didn't think that batteries would be viable.

As far as the protocol is concerned, to be honest I haven't looked closely at
the alternatives, but ethernet/wifi has a lot of support. Actually if it's
connected to the mains then a ethernet over power line solution is possible. I
use this to talk to the boiler/accumulator which is to far away from the main
part of the house for wifi to work.
