Energy Monitoring

Shelly Pro 4PM allows energy consumption to be monitored on each of the four channels. This makes it possible to control the power consumption of individual loads, analyze their operation and more easily identify irregularities, overloads and potential faults.

Energy consumption data can be used in automation scenarios and to optimize the operating costs of the electrical installation.

LAN and Wi-Fi Connectivity

The device is equipped with an RJ-45 Ethernet port and a Wi-Fi module. LAN connectivity provides stable communication with the local network, while Wi-Fi enables wireless integration with automation systems.

Shelly Pro 4PM can operate locally without requiring a cloud connection. This allows the main control and automation functions to be performed within the local network.

Graphical Display

The built-in color graphical display provides quick access to information about the device status. The user can monitor channel status, energy consumption, as well as messages and diagnostic information.

Automation and Integration

Shelly Pro 4PM offers extensive integration options with smart home and building automation systems.

The device supports:

• Shelly Cloud
• MQTT
• API
• Webhooks
• schedules
• local automation
• web interface

This allows it to be used as part of advanced Smart Home, BMS and building automation systems.

Applications

Shelly Pro 4PM can be used to control and monitor:

• lighting;
• electrical sockets;
• heating;
• air conditioning;
• pumps;
• garage and entrance gates;
• selected electrical appliances;
