Domotics

  • Domotics is the study of applications of information technology to create intelligent home environments.
  • French Journalist Bruno de Latour coined the term domotic in 1984 as a composite of the Latin word domus and informatics. In the 1990s the term was introduced in Spain and Italy as "Domótica". It literally means intelligent houses, through the use of automation technologies and computer science.

How to send a command?

  • Controls sends a command to the bus with the address of the right actuators…

The address is something like this:

  • A = 1 (A 🡪 Ambient)
  • PL = 1 (PL 🡪 Light point)
  • Different programming approachs:

Point to point, Ambient, Group
