My experience in the world of home automation is that, when selecting
the technology (X10, ZWave, etc.) you should look at the whole chain:
- whether you can find software to control it
- whether you can find hardware to control it (typically a RF transmitter
  device)
- whether you can find end devices (switches, thermometers, etc.) that
  do what you need

Whether the protocol is open or not does not matter much, unfortunately.
What really matters is whether it has been sufficiently reverse
engineered.

The fancy new technologies don't have that many end devices available,
or they are fairly expensive. (Or you might want to design your own
devices, but that's not something I was willing to do)

I've had some success with:
- software: domoticz (not in Debian, but Debian-friendly, and there's an
  ITP). I mostly use it through its REST API to automate stuff or get data
  (into a munin plugin for example)
- hardware controller:
  + a USB ZWave dongle
  + RFPlayer, a multi-protocol gateway that understands many
  (proprietary) protocols (but the firmware is closed source). There's
  another one on the market with a different set of protocols, called
  RFXCom
- end devices:
  Zwave remove switches (beware of the max power they can handle if you
  want to control your heater), Oregon thermometers, OWL energy monitor,
  Zwave and Deltia Dore "pilot wire" devices (for electric heaters controller),
  roller shutters (note that there's two protocols on the market, and
  only one of them has been reverse engineered).
