The Shelly Uni came out at 2020 autumn and became the smallest smart device straight away. 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. This small relay knows a lot:

  • 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 3xDS18B20 temperature sensors or 1Х 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 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.

This tiny device can fit everywhere you desire. Even though there is no plastic box sourranding it, the transparent cover over the chip insulates and protects it from any possible dangers to the device or your home appliances. 

Tip: The wide range of power supply and flexibility makes Shelly UNI the best choice for monitoring and controlling your camper. Make it as comfortable as being at home with one of the best home automation solutions! Power control, light control, door state, air temperature, water temperature, water level monitor, leakage.

It provides you flexibility with no limits: The two available digital inputs allow for the detection of any voltage from  to 36V and automatically send a notification to your phone, activating a scene of Shelly Cloud, or switching on the outputs. You can connect your Shelly to your old doorbell and give it intelligent functions, such as receiving a notification to your phone every time somebody is ringing your door.

You can build it into home appliances to give them intelligent functions. The Dual range of Shelly UNI enables you to connect any analog sensor and measure it. Connect your liquid level sensor to Shelly UNI and measure the level of, or even automate teh filling system.
