About this product
The Shelly 1 Gen3 bundle contains 4 identical smart relays, each with a 16 A potential-free (dry) contact at 240 V~ and Wi-Fi 2.4 GHz plus Bluetooth control. The voltage-free output fully isolates the switched circuit from the module supply, so you can switch lights, sockets, a pump, a gate or a gas boiler with no voltage limits.<br><br>Every module accepts flexible 110-240 V~ or 12 / 24-48 V DC power, fits inside a wall box and is configured from the Shelly Smart Control app. Four units in one box lower the per-unit cost and let you equip 4 rooms or circuits at once - a practical answer for a Chisinau flat, a renovation or an installer project.<br><br>Native integration with Home Assistant, Google Home, Amazon Alexa and SmartThings, plus MQTT, scripting and webhooks for local automation. 24-month CasaSmart warranty.

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
During a Chisinau renovation you fit one relay each on the living-room, bedroom, kitchen and hallway lights, all controlled from the Shelly app.
Four modules for four different rooms or circuits, installed from a single box.
One module switches the boiler thermostat, the other three serve the pump, gate and outdoor light.
The potential-free output starts the boiler straight on its control input, carrying no voltage of its own.
The integrator takes one set to site and equips four points in a single day.
A single stock code with 4 units for multiple jobs and a lower per-unit cost.

Frequently asked questions
How many units are in this set?
The set contains 4 identical Shelly 1 Gen3 modules in one box plus documentation. Each module is the standard unit, with no extra accessories.Does it measure power consumption (PM)?
No. The Shelly 1 Gen3 is a simple dry-contact relay and does not measure power. For metering, choose a model from the PM series.Does it support Matter or Zigbee?
No. The Shelly 1 Gen3 communicates over Wi-Fi 2.4 GHz and Bluetooth 4.2 BLE. Matter and Zigbee are not supported in this generation.What is a dry contact and why does it matter?
A dry (potential-free) contact means the relay output carries no voltage of its own. You can control a boiler, a gate or a low-voltage circuit without injecting 230 V.What maximum load does one module handle?
Each module switches up to 16 A at 240 V~ or 10 A at 30 V DC. The supply accepts 110-240 V~ or 12 / 24-48 V DC.Can I wire all 4 modules to the same neutral?
Not recommended. Each module needs its own neutral connection and space in the wall box. Plan separate wiring for each unit before installation.
