How many modules are in the Shelly 1 Gen4 (4-pack)?

The pack contains four identical Shelly 1 Gen4 modules in one box, each with its own wiring. It is the same unit sold individually, just bundled to equip four circuits at a lower per-unit cost.

What is the maximum load of each relay?

Each module switches up to 16 A at 240 V~ or 10 A at 30 V DC through a potential-free dry contact, so it can control lighting, a water heater, pumps, gates or low-voltage circuits.

Which wireless protocols does the Shelly 1 Gen4 support?

Generation 4 has Wi-Fi 2.4 GHz (802.11 b/g/n/ax), Bluetooth 5 LE, Zigbee 3.0 and Matter. It ships as a Matter device and can be switched to a Zigbee profile. Thread is not supported.

Does it need a neutral wire to install?

No, a neutral is not mandatory for the supply, which simplifies installation in older back boxes. Each module still connects separately in its own back box or panel according to the load it controls.

Does it measure power consumption (PM)?

No. The Shelly 1 Gen4 is an on/off switching relay without power metering; its own consumption is below 1 W. If you need energy monitoring, choose a Shelly model with PM.

Which smart home ecosystems is it compatible with?

It integrates with the Shelly Smart Control app and, via Matter or cloud, with Google Home, Amazon Alexa and Samsung SmartThings. CasaSmart offers a 24-month warranty and delivery across Moldova.

About this product

Shelly 1 Gen4 (4-pack) is a set of four universal smart relays designed to equip a whole flat or project in a single purchase. Each module switches loads up to 16 A at 240 V~ through a potential-free dry contact, so it works for lighting, a water heater, a pump, a gate or any 230 V appliance, as well as low-voltage circuits at 12-48 V DC.<br><br>The Gen4 modules are the most connected in the Shelly range: Wi-Fi 2.4 GHz (802.11 b/g/n/ax), Bluetooth 5 LE, Zigbee 3.0 and Matter. The device ships as a Matter device by default and can be switched to a Zigbee profile, so it slots into almost any ecosystem - the Shelly Smart Control app, Google Home, Amazon Alexa or SmartThings.<br><br>The compact 37x42x16 mm body fits behind most switches and inside back boxes, while no-neutral operation simplifies wiring. An internal temperature sensor and overheating protection keep the installation safe. Buying the 4-pack gives you a lower per-unit cost and four identical modules - ideal for installers and full renovations.

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

Fit one module each on living-room light, bedroom light, water heater and pump, controlled by app or voice.

Four circuits of the flat become smart at once.

An integrator in Chisinau equips a project with identical modules from the same batch and firmware.

Starter set for an automation site.

One module drives the gate motor, another the irrigation pump, the rest handle lighting.

Dry contact to drive devices without supplying power.
