Open box Smart relay Shelly Pro 2PM - 2 channels with energy meter, WiFi, LAN, DIN rail, app control, compatible with Amazon Alexa, Google Assistant and Home Assistant

What does "open box" mean?

Open-box products are returned products with opened or damaged packaging, but fully checked from a technical point of view and completely functional. They come with the same warranty as new products.

Shelly Pro 2PM combines the two independent channels of the Pro 2 with energy metering on each individual channel, giving you both control and full visibility of the consumption of each circuit. Like the basic version, it can work as two separate relays or as a dedicated pair for electric roller shutters and blinds, this time with positioning calibrated by operating time and power drawn, for a precise stop at the end positions.

Being mounted on a DIN rail in the electrical panel, the Pro 2PM is aimed at installers and users who want a robust and scalable system. Wi-Fi, Ethernet and Bluetooth connectivity work simultaneously, and the AC 110-240V or DC 12-24V power supply allows flexible integration. Overcurrent and overvoltage protection on each channel increases safety in installations with variable loads.

A concrete example of use is automating an electric roller shutter with consumption reporting, useful for spotting a motor that is starting to jam or drawing abnormal power, or separately controlling two switched sockets with individual monitoring of each connected appliance. Local integration, with no mandatory cloud, and compatibility with Home Assistant, MQTT and an open API make the Pro 2PM a versatile device for professional projects.

Practical use cases

• Mounted in the electrical panel, it controls a roller shutter or an electric blind in the dedicated mode, with calibrated positioning and motor consumption reporting, useful for spotting early a motor that is starting to jam.
• Controls two socket or lighting circuits separately, with power, voltage and current metering on each channel.
• Integrated into Home Assistant or via MQTT, it enables local automations, with no mandatory cloud, based on the consumption measured on each circuit.
• Connected via Ethernet, it provides a stable link in panels where the Wi-Fi signal is weak, with Wi-Fi and Bluetooth available in parallel.

Technical specifications

Shelly Pro 2PM meets the need for simultaneous control and metering of two circuits, whether lighting, sockets or electric roller shutters, in a single professional module.
