Shelly Plus 1PM UL WiFi Smart Relay Switch with Power Metering

Description

Product Overview

The Shelly Plus 1PM UL is a compact Wi‑Fi enabled smart relay designed for modern home and commercial automation. Measuring just 1.5 x 1.65 x 0.67 inches and weighing under one ounce, this device easily fits into standard electrical boxes without compromising on performance. It is UL certified, ensuring compliance with rigorous safety standards, and supports up to 15 A of continuous load, making it suitable for lighting circuits, small appliances, and HVAC components.

Beyond simple on/off control, the Plus 1PM incorporates a high‑precision power metering chip that provides real‑time voltage, current, and energy consumption data. This information is accessible through the Shelly app, allowing users to track usage patterns, set energy‑saving thresholds, and receive alerts when consumption exceeds predefined limits. The built‑in Bluetooth gateway extends the device’s connectivity, enabling it to act as a repeater for other Bluetooth‑enabled IoT devices, thereby strengthening the overall network reliability.

Connectivity is powered by a dual‑band Wi‑Fi module that supports both 2.4 GHz and 5 GHz networks, ensuring stable communication even in congested environments. The device integrates seamlessly with popular voice assistants such as Amazon Alexa and Google Home, allowing for voice‑controlled operation and scene creation. Firmware updates are delivered over‑the‑air, guaranteeing that the device remains up‑to‑date with the latest security patches and feature enhancements.

Usage

Designed for versatility, the Shelly Plus 1PM can be deployed in a wide range of scenarios. In residential settings, homeowners can replace traditional wall switches with the Plus 1PM to gain remote control over living‑room lighting, bedroom lamps, or kitchen appliances. The power metering capability enables users to identify energy‑hungry devices, encouraging more sustainable consumption habits.

For small businesses and office environments, the relay offers a cost‑effective solution to automate conference room lighting, coffee makers, and climate control units. By linking the device to the Shelly app, facility managers can schedule equipment to power down after business hours, reducing electricity costs and extending the lifespan of the hardware.

Because the unit functions as a Bluetooth gateway, it can also serve as a bridge for other Bluetooth sensors, such as temperature or motion detectors, consolidating data streams into a single, manageable platform. This makes the Shelly Plus 1PM an ideal component for building smart security systems, where motion‑triggered lighting or door‑lock automation can be coordinated through a unified interface.
