Three-phase DIN rail energy meter with Ethernet and three 120 A clamps / Energy meters
Shelly Pro 3EM 120A v2 is a good choice for a planned three-phase monitoring project, with three clamps, Ethernet and useful local records. At €157.90, it earns its price when those capabilities are needed. It is overkill for checking one appliance, and it cannot switch a large load on its own. Buy the current v2 for its confirmed Matter update path; the discontinued original listing is an easy buying mistake.
