The Shelly Plus Uni, based around an ESP32 module, brings smart functionality to your old appliances, suitable for low-voltage applications. It features two potential-free dry contacts that can switch 9-28VDC/8-24VAC and can monitor power usage in 2 ranges (0-15 VDC, 0-30VDC), as well as one analog input, two digital inputs and a 1-wire interface allowing you to work with various analogue and digital sensors.
With its new pulse counting feature, you're not just automating – you're getting insightful monitoring of your home’s usage. Designed for durability, its transparent cover offers full protection, ensuring both the device and your home appliances are always safe.
The Uni connects to your WiFi network without the need for a dedicated hub, and the onboard Bluetooth allows quick inclusion and also acts as a Bluetooth gateway. Shelly Plus Uni fully supports scripting, allowing you local control and custom functionalities.
