I really aggree.

Or if there are bridges

For myself, I'm using :
- software :
  - openhab for the central part (not in Debian, but also
    Debian-friendly with deb package on upstream site. It is written
    in java and handle lots of different protocol/software)
  - owfs + scripts to interact with openhap
  - scripts with serial com to bridge a video-projector and openhab
  - scripts to interact with Denkovi hardware.
- hardware :
  - 1-wire for temperature and for relay I/O (hand made) mainly
    for roller-shutters (simulate pressing on remotes with
    proprietary protocol)
  - Denkovi hardware for digital Input and Output (relay) (http/
    snmp/... on network interfaces)
  - Velux (root windows) => not integrated into my current setup
    as it uses a interoperable (only with a few other companies
    such as somfy) proprietary protocole (IO-homecontrol) :-(((
      However, it seems that, after several years, a bridge
    is eventually available (KLF200). I will probably try it in a
    few weeks.
