Shelly UNI

What is Shelly UNI?

Shelly UNI is the smallest universal module with two available digital inputs and potential-free outputs, providing endless functionalities to make any old appliance smart!




Universally Small

Shelly UNI is the smallest universal module with the ideal size of 20 x 33 x 13mm (0.78 x 1.29 x 0.5 in)

Flexible Power Supply

Shelly UNI can be powered with the wide range of 12V-36V DC and 12V-24V AC

Universal Digital Inputs

Includes 2 digital inputs, which can support differing voltages and work separately from 2.2-36V DC and 12-24V AC

Universal Outputs

The two potential-free outputs allow control from inputs or separately, and can switch up to 36VAC and 24VDC, with a maximum current of 100 mA each.

Universal ADC

The ADC range can measure any voltage from 0 to 30 VDC. Dual ranges from 0-12V and 12-30V give exceptionally high accuracy

Temperature Sensors

Shelly UNI supports up to 3xDS18B20 temperature sensors or 1Х humidity sensors, making it possible to trigger outputs, local and cloud scenes.

Universal Resistance

With no plastic cube, the transparent insulation cover over the chip protects it from high humidity, dust, and the threat of short circuits during its long working hours.
