RELAY UNIT SHELLY 1PM GEN3

Shelly 1PM Gen3 is a WiFi-controlled single-channel 16A relay with built-in power metering (PM = Power Metering). It is designed to be installed behind a switch, socket, or light outlet, enabling easy control and automation of lights, sockets, and all electrical devices. Thanks to its compact design, it fits into most wall and ceiling boxes.

Shelly 1PM Gen3 is easy to install and control via the Shelly Smart Control app or your preferred smart home system. Shelly devices operate 100% locally and require only a local network to function. Shelly can be used independently via the Shelly Smart Control app or integrated with over 200 partner systems such as Google Home, Amazon Alexa, Home Assistant, Samsung SmartThings, Athom Homey, and many others.

Features Shelly 1PM Gen3 offers a wide range of applications. It can be powered by 24-30V DC or 110-230V AC. The device has one switch terminal, which is optional and fully programmable. It automatically measures power consumption, which can be monitored via the Shelly Smart Control app and easily used in automation scenarios. Shelly 1PM Gen3 is suitable for many purposes, such as:

• Light control
• Socket control
• Heating control (electric heaters, infrared heating panels, etc.)
• Water heater (e.g., can automatically turn on the water heater when electricity is cheap)
• Pumps
• Power consumption monitoring for washing machines, dryers, and similar appliances.

Works locally – no gateway required

All Shelly WiFi devices have a built-in web server, meaning you get extensive functionality that always works, regardless of whether you have an active internet connection or not. No gateway is required, so you can start with just one Shelly device. Thanks to the built-in web server, Shelly has built-in memory and remembers sunrise, sunset, schedules, and more, even if the network goes down. Relays and dimmers function like standard push-button relays, so you can use them with regular switches—even without internet. All input and output connections are fully programmable and require only a local Wi-Fi network to communicate between devices. However, we recommend keeping an active internet connection, as it unlocks additional features.

Connections

Shelly 1PM Gen3 can connect to the internet or a local network via 2.4 GHz Wi-Fi. Additionally, the device has built-in Bluetooth, like other Pro and Plus devices, allowing it to serve as a gateway for Shelly Bluetooth battery-powered Bluetooth devices.

All Shelly devices operate locally without requiring a connection to Shelly Cloud, but activating it is recommended to enhance data storage and functionality. Devices can also communicate via MQTT, HTTP, and WebSocket. All support TLS.

Hardware

The device features third-generation hardware, including the powerful ESP-Shelly-C38F CPU with 8MB flash memory. This makes the Shelly 1PM Gen3

future-proof and enables script functionality and virtual devices for advanced and user-specific operations.
