Shelly UNI

Make all your devices smart with the Shelly Uni. A universal module, connected via WiFi and compact enough to be built-in.

This ultra-compact smart implant is a 12V-36VDC or 12V-24VAC in-wall switch and sensor, with 2 digital inputs and 2 potential-free switchable/controlable outputs. Although it lacks a plastic casing, the transparent insulation cover over the chip protects it from high humidity, dust, and the risk of short circuits during long operational hours.

Optionally, you can also order sensors, a 12VDC or 24VDC power adapter, and/or protective housing by checking the box. We now also offer the Shelly Plus UNI.

The ADC (Analog to Digital Conversion) range measures any voltage from 0-30VDC. Dual ranges of 0-12V and 12-30V ensure exceptionally high accuracy. For example, you can connect a hygrometer to measure soil moisture for your irrigation system.

The Shelly UNI supports up to 3xDS18B20 temperature sensors or 1x DHT22 temperature and humidity sensor, allowing you to activate outputs or local and cloud scenes based on temperature or humidity. There is also a 3m DS18B20 sensor available.

Imagine you have a security system and want to integrate it into your Smart Home System so you can read the status, remotely turn the alarm on and off, and receive notifications on your smartphone if something goes wrong, from anywhere in the world. The Shelly Uni makes this possible by connecting it to a free zone and the so-called key switch.
This way, virtually any (old) device can be made smart by simply placing this smart implant between the buttons (switches) and the circuit board, as long as the switch is 2.2-36VDC or 12-24VAC low-voltage with a maximum of 100mA per output. Think of your doorbell, thermostat, air conditioner, espresso machine, audio/video equipment, electric garage door, etc. However, for higher power switching, go for the Shelly 1 relay switch.

The Shelly Uni supports 12V-36VDC or 12V-24VAC and has an ESP8266 with a flashable chip built-in. This allows you to flash your own or alternative firmware, such as Tasmota or HomeKit. You will need a USB-to-UART 3.3V and at least a 350mA adapter, like our FTDI adapter. The best part is, you don't even need to open the Shelly. Flashing is simple through the directly accessible pins.

If you'd rather not use the free Shelly cloud service but still want to control your devices remotely, that's no problem. The Shelly Uni also supports basic MQTT (Message Queue Telemetry Transport) for reliable connections via a central mediator: the MQTT broker. The involved devices communicate only with the broker and do not know each other. They do not need to know the IP addresses and technical details of other participants. So, it's secure and reliable, with real-time monitoring and easy integration.
