Adding a smart home device to the app
A tiny universal module that makes any device smart
The Shelly Plus Uni is a tiny wireless smart accessory (3.7 x 4.2 x 1.6 cm) from Shelly’s innovative product line, for smart control and monitoring of electrical devices, sensors and more from the app, with quick, simple installation and a direct connection to your Wi-Fi network.
The Shelly Plus Uni accepts operating voltages of 5 VDC, 9 to 28 VDC and 8 to 24 VAC, and has a protective coating against moisture, dust and short circuits, so it can be installed inside electrical devices without a plastic enclosure.
It can count pulses to measure water, gas or energy, and you can connect up to five temperature sensors or a single humidity sensor. Most Arduino sensors work with it too, so you can trigger scenes based on readings. It also has two separate digital inputs and one analog input, plus two outputs that can switch up to 36 VAC and 24 VDC at a maximum current of 100 mA each, so you can connect many types of analog sensors for monitoring and control. The Shelly Plus Uni can also measure voltages between 0 and 30 VDC with high accuracy.
It connects easily to your Wi-Fi network, and you can operate it and create scenes both in the Shelly Smart Control app and in the Google, Apple and Samsung smart home apps. It also supports the REST, MQTT and CoAP protocols.

Who it’s for
A tiny smart module for projects: it makes a device that runs on low voltage (5 to 28 V DC or 8 to 24 V AC) smart, counts pulses from a water or gas meter, and connects up to 5 temperature probes or a humidity sensor. Great for irrigation systems, gates, heating boilers and anyone who likes to build things themselves. For standard Shelly devices, there’s Plus Add-on for connecting sensors.
What to know before installing
- Works on low voltage only, not on 230 V.
- It has a protective coating, so it can be installed inside a device.
- 2.4 GHz Wi-Fi.
FAQ
Can it measure water use?
Yes, with a water meter that has a pulse output.
Can I connect a soil moisture sensor?
Yes, for example VH-400 for watering only when needed.
Is it suitable for a car or a camper?
Yes, as long as the voltage is within 5 to 28 V DC.
