About this product
Shelly 1 Gen4 in a 2-pack is the right choice when you need to automate more than one circuit at once: two rooms, two lighting groups or a small project end to end. Each module switches loads up to 16 A at 240 V~ through a potential-free (dry) contact, which makes it compatible with lighting, boilers, pumps, gates and even low-voltage circuits.<br><br>The fourth generation adds full connectivity: Wi-Fi 2.4 GHz, Bluetooth 5 LE, Zigbee 3.0 with repeater function and Matter. You can start with the Shelly Smart Control app and later integrate the modules into Home Assistant, Google Home or Apple Home without changing any hardware.<br><br>Buying two modules together lowers the per-unit cost and keeps spares ready for a complete residential project. Both relays run on 110-240 V~ or DC (12 V / 24-48 V), draw under 1 W and measure a compact 37x42x16 mm, fitting behind a standard wall switch.

Frequently asked questions
What is included in the Shelly 1 Gen4 2-pack?
The box contains two identical Shelly 1 Gen4 modules, each with its own 16 A dry contact. They are separate units, each with its own wiring and setup.Does the Shelly 1 Gen4 measure power consumption?
No. The Shelly 1 Gen4 is the base model without power metering (no PM); it only switches the load via the dry contact. For energy monitoring choose a PM model.Which wireless protocols does the 4th generation support?
Each module has Wi-Fi 802.11 b/g/n/ax on 2.4 GHz, Bluetooth 5 LE, Zigbee 3.0 with repeater function and Matter compatibility. It has no Thread.What maximum load can each relay switch?
Up to 16 A at 240 V~ or 10 A at 30 V⎓ through the potential-free (dry) contact, with overheating protection. Power can be 110-240 V~ or DC 12 V / 24-48 V.Can I integrate the modules into Home Assistant or Apple Home?
Yes. Thanks to Matter and Zigbee 3.0, both modules work with Home Assistant, Google Home, Apple Home and Alexa, or directly via the Shelly Smart Control app.Do you offer installation in Chisinau for this set?
Installation is not included in the price, but the CasaSmart team in Chisinau can take on design and installation as a separate service. We recommend a licensed electrician because the work involves 230 V.
