Why a two-pack instead of a single relay?

The set brings two identical Shelly 1 Mini Gen3 modules in one box, so you can equip two circuits during a single electrician visit or keep one module as a spare.

What load does each module switch?

Each module switches up to 8 A at 240 V AC (up to 2000 W) or 5 A at 30 V DC through a normally open one-pole dry contact.

Does it measure energy consumption?

No, the Shelly 1 Mini Gen3 has no built-in power metering. For consumption monitoring choose the Shelly 1PM Mini Gen3 version.

What wireless protocols do the modules use?

Each module uses 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth 4.2; there is no Zigbee or Thread.

Will it fit a standard back box in Chisinau?

Yes, the 29x35x16 mm body and 19 g weight allow installation in a standard back box, behind a switch or in a luminaire box.

What systems does it integrate with?

The modules work with the Shelly app, Home Assistant, Google Home and Amazon Alexa, and support MQTT, scripts and webhooks for advanced automations.

About this product

The Shelly 1 Mini Gen3 is a compact Wi-Fi relay with a dry (potential-free) contact that tucks into the back box behind a switch, light fixture or socket. This set ships two such modules in one box, so you can equip two independent circuits at the same time or keep the second module as a spare.<br><br>Each module switches a load of up to 8 A at 240 V AC (up to 2000 W) or 5 A at 30 V DC. The supply is 110–240 V AC and its own consumption stays below 1.2 W. The normally open dry contact lets you control not only lighting but also gates, a boiler, a pump or low-voltage circuits.<br><br>Connectivity comes from 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth 4.2. The 29x35x16 mm body and 19 g weight let the module fit even into tight mounting boxes. Schedules, scenes, webhooks and scripts are supported, alongside integration with Home Assistant, Google Home and Amazon Alexa.

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

One Shelly goes behind the bedroom switch, the second behind the living room switch; both circuits turn on by schedule and by voice.

Two modules control lighting in different rooms independently.

The first relay sends the boiler start command, the second opens the sliding gate as you approach the house.

The dry contact drives low-voltage inputs without applying 220 V.

After one relay is installed, the second is kept for future automation of a pump or water heater.

The second module stays in reserve for expansion or replacement.

Analytics
