A process for communication between two elements being part of a single phase or three-phase electrical energy distribution network for a home or industrial premise, the process comprising the steps of: - assigning a first IP address to a first element of the electrical energy distribution network, wherein said first element is a wall switch including a first electronic circuitry comprising first memory circuits (563, 564) configured for the storage of a first MAC - Media Access Control - address according to the IP protocol, wherein said first IP address is assigned during a configuration phase using the first MAC address; - assigning a second IP address to a second element of the electrical energy distribution network, wherein said second element is a two-wires plus ground wall outlet or a light connection device comprising a second electronic circuitry (360, 460) comprising second memory circuits (362, 363, 463, 465) configured for the storage of a second MAC address, wherein said second address IP is assigned during a configuration phase using the second MAC address; - establishing a communication between said first and second elements of the electrical energy distribution network, wherein said first and second IP addresses are exchanged so as to create an association between said first and said second elements so as to control said wall outlet or said light connection device by means of said wall switch thanks to the exchange of IP packets; - assigning a third IP address to a third element which is a circuit breaker comprising a third electronic circuitry comprising third memory circuits (262, 263à configured for the storage of a third MAC address, wherein said third address IP is assigned used during a configuration phase using the third MAC address, wherein said circuit breaker is configured for the storing of routing tables of packets and IP addresses of the elements composing the network so as to allow a communication between said first and said second elements. - assigning a first IP address to a first element of the electrical energy distribution network, wherein said first element is a wall switch including a first electronic circuitry comprising first memory circuits (563, 564) configured for the storage of a first MAC - Media Access Control - address according to the IP protocol, wherein said first IP address is assigned during a configuration phase using the first MAC address; - assigning a second IP address to a second element of the electrical energy distribution network, wherein said second element is a two-wires plus ground wall outlet or a light connection device comprising a second electronic circuitry (360, 460) comprising second memory circuits (362, 363, 463, 465) configured for the storage of a second MAC address, wherein said second address IP is assigned during a configuration phase using the second MAC address; - establishing a communication between said first and second elements of the electrical energy distribution network, wherein said first and second IP addresses are exchanged so as to create an association between said first and said second elements so as to control said wall outlet or said light connection device by means of said wall switch thanks to the exchange of IP packets; - assigning a third IP address to a third element which is a circuit breaker comprising a third electronic circuitry comprising third memory circuits (262, 263à configured for the storage of a third MAC address, wherein said third address IP is assigned used during a configuration phase using the third MAC address, wherein said circuit breaker is configured for the storing of routing tables of packets and IP addresses of the elements composing the network so as to allow a communication between said first and said second elements.
