several edits for deployment
 - disabled room light controls (only hall down for ilustration)
 - outdoor dao hardcoded graph deleted
 - room spec (even though not used actually) now uses MCP23017 Pins as
   expected for the future
 - Reading temperatureB changed to temperature and temperatureD now not
   returned from the other sensor
 - gpio observable sensor now allows to flip HIGH->LOW values - usefull
   e.g. for button switched, where HIGH actually means off, changed
   light capable support for factories accordingly
