It all depends on what is present in the installation, but normally it is enough to add:
• 1 connected load shedder ref. 4 121 72 or 1 connected single-phase energy meter ref. 4 120 15 for consumption measurement (if not already present)
• 1 connected single-phase energy meter ref. 4 120 15 for production measurement
In addition, it will be possible to take advantage of the "automation" function thanks to the "with Netatmo" commands present in the installation or to be added (contactors, dry contacts, sockets, etc.).
