Let your Pro 3EM act on what it measures.
What it does
The Pro 3EM meters only measure. This add-on gives them a way to act. It mounts on the DIN rail, attaches to the side of a Shelly Pro 3EM and takes its power from the meter, adding one galvanically isolated dry-contact output.
With it, your electrician can have the meter drive a contactor that sheds a geyser, pump or other heavy load when demand climbs past a limit you set, or follow a schedule built around load-shedding. You control the output in the Shelly Smart Control app alongside the meter's readings, and an internal sensor reports the module's own temperature.
What you need
Works only with a Shelly Pro 3EM meter, which powers it and controls the output.
- Required
Needs a Shelly Pro 3EM meter, either the 120 A or the 400 A version, to attach to.
