About this product

The Shelly 1PM Gen3 (2-pack) bundle includes two compact smart relays with energy metering, designed to automate two separate circuits in an apartment or house in Chisinau with a single purchase. Each module switches loads up to 16A at 240V (about 3840W) and measures power, voltage and consumed energy in real time, with the data visible in the Shelly Smart Control app.<br><br>Both modules install hidden inside the wall box, behind a switch or a socket, thanks to the 37x42x16 mm housing. The 2.4GHz Wi-Fi and Bluetooth connection allows control from anywhere, while the built-in web interface provides advanced configuration without a cloud account.<br><br>The two-piece set is ideal for installer projects and renovations: cover, for example, the water heater and boiler, or the living-room and bedroom lighting, lowering the per-unit cost versus buying separately.

Smart scenarios

Three typical automations we set up after the install.

01Morning: warm light + blinds up + climate at 22 °C
02Leaving: lights off, arm sensors, close the gas
03Evening: warm ambient + cinema scene

Where it works

Use cases

Schedule water heating during off-peak tariff hours and track each appliance separately.

The two modules control and measure the consumption of the water heater and the heating boiler.

With a single evening scenario, automatically turn off the lights in both rooms.

One module for the living room, another for the bedroom, both controlled from the same app.

The installer equips the washing-machine socket and the lighting circuit in the same visit.

The 2-pack covers two circuits in a renovation at a lower per-unit cost.

Analytics

See consumption — save on bills

Real-time consumption tracking via the eWeLink app. Daily, weekly and monthly history helps identify the most energy-hungry devices.
