Home automation device having an alternative communication link with a remote computer server

A home-automation device comprising:

• a first home-automation computing unit, named main computing unit (30),
• an electronic device, named receiving device (35), connected to said main computing unit (30) by a first data communication link, named main link (33),
• said main computing unit (30) belonging to a first local network, named main local network (32), of electronic devices which are distinct and remote from the receiving device (35), this main local network having its own access, via a password, to the Internet, said main link comprising a communication link of the Internet,
• said main computing unit (30) being adapted to:
• receive signals, named home-automation signals, of at least one home-automation sensor (56), of the main local network,
• process said home-automation signals and produce digital data representing a message, named home-automation message, based on said home-automation signals,
• be able to emit said home-automation message to said receiving device (35) by said main link (33),
• further comprising a second home-automation computing unit, named neighbouring computing unit (38, 43), belonging to a second local network, named neighbouring local network (40, 45), of electronic devices which are distinct and remote from the receiving device (35), this neighbouring local network having its own access, via a password, to the Internet, said neighbouring link comprising a communication link of the Internet,
• wherein said receiving device (35) is connected to said neighbouring computing unit (38, 43) by a second data communication link, named neighbouring link (37, 46), distinct from the main link (33),
• and wherein said main computing unit is adapted to:
• be able to detect a cut in said main link (33),
• be able to establish a data communication link, named translocal link (36, 55):
• distinct from said main link (33),
• distinct from said neighbouring link (37, 46),
• with said neighbouring computing unit (38, 43),
• upon detection of a cut in said main link (33), be able to re-emit said home-automation message to said neighbouring computing unit (38, 43) by said translocal link (36, 55),
• and wherein said neighbouring computing unit (38, 43) is adapted to:
• be able to receive, over said translocal link (36, 55), said home-automation message from said main computing unit (30),
• be able to emit said home-automation message to said receiving device (35) by said neighbouring link (37, 46).

A method implemented in a home-automation computing unit, named main computing unit (30), in which said main computing unit:

• receives signals, named home-automation signals, of at least one home-automation sensor (56),
• processes said home-automation signals and produces digital data representing a message, named home-automation message, based on said home-automation signals,
• emits signals representing a message, named home-automation message, to a receiving device (35) by a first data communication link, named main link (33), comprising a communication link of the Internet, said main computing unit belonging to a first local network, named main local network (32), of electronic devices which are distinct and remote from the receiving device (35), this main local network having its own access, via a password, to the Internet,
• wherein said main computing unit:
• detects a cut in said main link (33),
• re-emits said home-automation message over a data communication link, named translocal link (36, 55), distinct from the main link (33), to a second home-automation computing unit, named neighbouring computing unit (38, 43), adapted to be able to emit said home-automation message to said receiving device (35) by a second data communication link, named neighbouring link (37, 46), comprising a communication link of the Internet, distinct from the main link (33), said neighbouring computing unit (38, 43) belonging to a second local network, named neighbouring local network (40, 45), of electronic devices which are distinct and remote from the receiving device (35), this neighbouring local network having its own access, via a password, to the Internet.
