Shelly 1 Gen3 dry-contact smart relay

The Shelly 1 Gen3 is a compact wireless smart relay with a dry-contact output: the output circuit is isolated from the input circuit, so it can switch 0 to 220 V AC/DC regardless of its own supply voltage. The new generation of the Shelly Plus 1, it is designed to control a single lighting circuit, a water heater, a bathroom heater, an air conditioner, an electric gate, outlets, a radiator, irrigation valves or any electrical device up to 16 A.
It works with a range of supply voltages, as listed in the specifications.

The Shelly 1 Gen3 is small enough to fit behind a standard switch, inside a light fixture or in a junction box. The switch keeps working as usual, while the Shelly adds a full range of smart home capabilities, making it just as useful at home and in the office as in industrial settings.
