Shelly Plus Uni Smart Wi-Fi Low-Voltage Micro-Module

The Shelly Plus Uni delivers unmatched low-voltage integration capabilities and hardware flexibility for modern automated retrofits and custom embedded engineering. This miniaturized chip-scale module is purpose-built to fit cleanly inside existing appliance shells, gate automation control boards, legacy security panels, or specialized industrial machinery. Operating across a safe, wide power spectrum of 12V to 24V in either AC or DC current, it functions as a universal transparent digital bridge between classic mechanical arrays and modern local networks.

Despite its microscopic physical footprint, the hardware package includes two isolated digital inputs designed to monitor status signals and an advanced analog input channel operating as an onboard voltmeter (0-30V) to continuously screen battery health metrics. For system interaction, it embeds twin independent potential-free dry contact outputs rated up to 1A, making it ideal for broadcasting low-voltage gate open impulses or triggering secondary pilot lines. Furthermore, an onboard data bus supports the direct attachment of one DHT22 humidity probe or up to five DS18B20 thermal sensors simultaneously.

Driven by the processing efficiency of the modern Plus series framework, the device implements Bluetooth channels for immediate provisioning and complete support for local JavaScript scripting engine logic. This allows system integrators to build self-contained, edge-computed conditional rules and timers directly on the hardware block without relying on external cloud infrastructure. Offering native interoperability with Home Assistant, industrial MQTT routing, and Webhooks, the Shelly Plus Uni is a premier choice for technical automation workflows.
