The Shelly Pro 1PM is a single-channel second-generation (Gen2) Wi-Fi relay in a DIN-rail enclosure that is one module wide (94 x 19 x 69 mm). The device switches AC loads of up to 16 A at voltages up to 240 V and is powered from a 110–240 V AC mains supply, which makes it suitable for integration into the distribution board of a single-phase electrical installation.<br><br>The defining feature of the Pro line is electrical metering directly on the DIN rail: a built-in AC voltmeter and ammeter let you monitor current, voltage and consumed power on the connected circuit without a separate meter. The readings are available in the embedded web interface and in the Shelly app.<br><br>Connectivity is provided on three levels: Wi-Fi 802.11 b/g/n, wired Ethernet via an RJ45 connector and Bluetooth 4.2 for local setup. The wired channel matters especially during panel mounting, where a Wi-Fi signal behind a metal cabinet door can be unstable. The device is built on an ESP32 processor and supports local control, scenes, MQTT and webhooks, as well as integration with Shelly Cloud, Google, Amazon Alexa and Samsung SmartThings.
