Product Description

The Shelly UNI is a highly compact universal Wi‑Fi module that smart‑enables devices and sensors by providing voltage inputs, analog measurement, and dry‑contact outputs. It fits behind switches or inside enclosures and requires no hub—ideal for integrating low-voltage systems into smart homes.

Key Features:

• Flexible Power Input: Works on 12–24 V AC or 12–36 V DC for versatile deployment

• 2 Digital Inputs: Compatible with 2.2–36 V DC or 12–24 V AC for monitoring switch states

• 2 Potential‑Free Outputs: Dry contacts switch up to 36 V DC or 24 V AC with 100 mA maximum per output

• Built‑in ADC: Measures 0–30 V DC in dual ranges (0–12 V & 12–30 V) for voltage sensing

• Sensor Support: Interfaces with up to three DS18B20 temperature probes or a DHT22 humidity/temperature sensor

• Smart Scheduling & Scenes: Includes timers, sunrise/sunset automation, and local logic control

• Protocol Compatibility: Supports REST API, MQTT, CoAP, and works with Alexa, Google Assistant, and custom automation platforms

• Ultra Compact Design: Just 20 × 33 × 13 mm; fits easily into most switch boxes or tight enclosures

• Built for Durability: Transparent protective overlay guards electronics from high humidity and dust while avoiding shorts

Usage Notes:

• Excellent for converting existing sensors, buttons, or circuits into smart devices

• Allows analog voltage reading or physical switch monitoring; pairing with automation hubs unlocks full potential

• Used widely to upgrade thermostats, detect gate or garage door status, integrate environmental sensors, or automate water and energy systems

• Works reliably with third-party platforms like Home Assistant, MQTT controllers, or REST-based environments

• Updates every few seconds when measurements or states change—can vary depending on external system polling
