Product description: Shelly 1PM Gen3 - 1-channel flush-mount relay / controller - WiFi / Bluetooth with energy measurement - Android / iOS application - 4 pcs.
Shelly 1PM Gen3 is a compact, single-circuit relay that allows you to remotely control devices from 110V to 240V AC or from 24V to 30V DC and monitor their energy consumption. Thanks to WiFi and Bluetooth connectivity, it can be easily integrated with home automation systems such as Google Assistant, Alexa or Samsung SmartThings, allowing for voice control and automation . Shelly 1PM Gen3 can be installed in standard electrical boxes , behind power sockets or in other places with limited space. The relay works both locally and in the cloud, and the new ESP-Shelly-C38F processor and 8MB of memory ensure fast and stable operation. The set of 4 allows you to expand the system throughout the home - from lighting to heating or office devices.

Shelly 1PM Gen3 module connection diagram
Before connecting the Shelly 1PM module, turn off the power supply in the circuit where it will be installed. Make sure it is located in a safe place, protected from the weather and inaccessible to unauthorized persons.
The module is equipped with six screw connectors to which you can connect the wires using a screwdriver. Here is a description of the individual connectors:
- O : potential-free output
- L1 / L : 230 V AC power supply (or 24 V to 30 V DC), positive pole
- SW : switch input that controls output O
- Debug port : used for diagnostics and testing of the module
Always remember to exercise caution when working with electrical equipment.
