Shelly Uni is the smallest universal module that can make any old appliance smart! With this tiny, insulated chip, you can control any sensor and measure it, such as a liquid level sensor to measure the level of, or even automate the auto-filling system. No more waiting around in the morning for your coffee machine to heat its water and prepare your coffee! Just connect it to Shelly Uni and switch it on remotely as you please, or on a set schedule.

Universally Small

With the ideal size of 20 x 33 x 13mm (0.78 x 1.29 x 0.5 in), Shelly Uni is the smallest universal module that can make any old appliance smart.

Universally Flexible Power Supply

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

Universally Digital Inputs

Includes 2 digital inputs, which can be 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.

Universal Temperature & Humidity Sensors

Shelly Uni supports up to 3 x DS18B20 temperature sensors or 1 x humidity sensors, making it possible to trigger outputs, local and cloud scenes.

Universal Protocols

Out of the box, Shelly Uni supports REST, MQTT, CoAP, Alexa, Google Home, and Samsung Smart Things, making it highly compatible with all major home automation platforms.

Universal Resistance

Even though there is no plastic casing, the transparent insulation covering the chip protects it from high humidity, dust, and the threat of short circuits during its long working hours.
