Shelly Plus Uni – compact Wi-Fi/Bluetooth I/O module
Shelly Plus Uni is an ultra-compact and versatile smart I/O module that makes it easy to connect and automate existing installations—ideal for mounting in a ceiling box, junction box, or other tight spaces. With built-in Wi-Fi and Bluetooth, setup is quick and reliable, and you can control it via the Shelly app, the local web interface, or integrate it with your preferred smart home system (e.g., Home Assistant).
The module features digital inputs and open-collector outputs, making it perfect for reading buttons/sensors and controlling external devices such as relays, LEDs, alarms, gate/door controllers, or other loads (using a suitable driver stage when needed). It can also be used for pulse counting and reading signals from various sensors. Based on the Shelly Plus platform, it delivers improved stability, faster performance, and advanced automation options.
