Shelly PRO 4PM WiFi + Ethernet 4-channel relay module with energy meter

4-channel DIN rail relay switch with Wi-Fi, LAN and Bluetooth connectivity

Professional 4-channel relay with Wi-Fi, LAN and Bluetooth connectivity, suitable for home and building automation with remote control and precise energy management. DIN rail mounting inside the junction box. Enhanced security features and compatibility with the most widely used smart home platforms.

The Shelly Pro line allows full smart automation directly from the junction box without additional cables or wiring. This makes it the ideal solution for new buildings and manufacturing plants that can be automated to suit your own or business needs. The PM's accurate metering features will keep you informed of the electricity consumption of each connected device, allowing you to analyse the data and reduce your electricity costs.

And like all Shelly devices, the Shelly Pro range can be managed directly and without a central hub via a smartphone using the Shelly Cloud app. Manage and control your home or facility, set up scenarios, monitor energy consumption data and adjust settings wherever you are - via cloud access or just on your local network!

Shelly Pro 4PM features include:

• LAN, Wi-Fi and Bluetooth connectivity
• 4 outputs, 16A each. Total maximum device load 40A
• Accurate measurement of energy consumption
• Overload and overvoltage protection at the output
• DIN rail mounting
• 1.8-inch colour display with navigation keys

PRO 4PM is the first member of the Shelly PRO product line, which offers the ultimate in home and building automation with the Shelly line of professional smart switches.

Enhanced with temperature, overload and overvoltage protection, the Shelly Pro series is designed to be installed inside a distribution box (DIN). It enables full smart automation without additional cables or wiring and is perfect for homes, offices, shops, businesses, manufacturing plants and new buildings.

DIN rail mounting

The Shelly Pro line is installed inside the junction box and is designed in accordance with global DIN rail standards. This makes it suitable for all types of buildings and allows easy installation without additional components.

Temperature protection - no risk of overheating in the junction box

In case of dangerous temperatures or rapid temperature rise, the device switches off the outputs and sends a notification. The internal temperature sensor measures the heat every 100 ms.

Overload protection - power metering devices protect against overload damage

When an overload is detected, the device switches off the outputs and sends an immediate notification. The overload protection function protects the device and other electrical equipment from possible damage.

Surge protection - protect your devices against surges with Shelly PRO devices with power metering

Voltage surges can be dangerous for electrical appliances and machinery. To avoid damage, the device switches off the outputs when an overvoltage is detected and sends an immediate notification.

Fire-resistant design (V-0) - fire-resistant materials for increased safety

All Shelly Pro components are made of flame-resistant materials and maintain their structure even at high temperatures.

SHELLY PRO PRODUCT LINE FEATURES:

• HTTP/HTTPS web calls for fast connection - with enhanced HTTP/HTTPS webhook connections, the Shelly Pro line easily connects to, notifies or monitors other compatible equipment or third-party automation systems.
• Smart actions that follow the sunrise/sunset - The Shelly Pro line can switch electricity on/off according to the hour of sunrise and sunset, ideal for seasonally tailored management of electrical equipment.
• Automation with scheduling - The Shelly Pro line allows you to set up to 50 actions according to your daily or weekly schedule, without the need for an external server or control hub.
• Scripting for customised automation - The Shelly Pro line fully supports the mjS scripting language, allowing users to create their own features and options! Shelly Pro devices allow multiple scripts to be executed at the same time, depending on different triggers such as I/O statuses, sensor data or WLAN requests.
