About this product
The Shelly 1PM Gen4 in a 4-pack is the practical way to automate a whole flat or a small project in one go. Each module is a smart single-channel relay that switches up to 16A (240 V~, about 3840 W resistive) and includes built-in current and voltage metering, so you can track the real consumption of every circuit.<br><br>Generation 4 adds multi-protocol connectivity: Wi-Fi 2.4 GHz, Bluetooth 5.0, Zigbee 802.15.4 and Matter compatibility. The modules work both in the Shelly app and in ecosystems such as Amazon Alexa, Google Home and SmartThings. The compact 37x42x16 mm body fits inside the back-box behind switches and sockets.<br><br>The pack of four is made for installers and renovators: equip living-room, bedroom, kitchen and bathroom lighting, or four key sockets, from a single purchase. Overheating, overvoltage, overcurrent and overpower protection guard each circuit independently.

Where it works
Use cases
When renovating a flat in Chisinau, fit one module each on living-room, bedroom, kitchen and bathroom lighting, each with its own metering.
Equip four main circuits of a flat with the four modules included in the pack.
See the water heater and boiler consumption separately and optimise their operating schedule.
Track in the Shelly app how much each circuit consumes thanks to built-in metering.
An electrician equips four rooms in one visit using identical modules, cutting installation time.
Standardised hardware for projects with identical firmware and configuration.

Frequently asked questions
How many modules does this set contain?
The set contains 4 identical Shelly 1PM Gen4 modules in one box. Each is a separate single-channel relay mounted individually on its own circuit.What maximum load does each module handle?
Each module switches up to 16A at 240 V~, around 3840 W for resistive loads, and up to 10A at 30 V DC.Which wireless protocols does Gen4 support?
Generation 4 supports Wi-Fi 2.4 GHz, Bluetooth 5.0, Zigbee 802.15.4 and is Matter-compatible, so it integrates into several network types.Can I use the 4 modules on different circuits?
Yes, that is the purpose of the pack. Equip four separate circuits, for example lighting in four rooms, with each module having its own wiring and metering.Which voice assistants does it work with?
The modules work with Amazon Alexa, Google Home and Samsung SmartThings, in addition to the Shelly app and Matter integration.Does the module fit in a standard back-box?
Yes. The 37x42x16 mm body fits in the back-box behind switches and sockets, and the accepted conductor cross-section is 0.5 to 4 mm squared.
