Basic wiring diagram
NOTICE! Shelly Plus Uni inputs are different from the previous Shelly Uni ones.
No, the protocol is used only for device inclusion, allowing for quick and easy setup through the Shelly Smart Control app.
For bluetooth control it is required to have another Bluetooth device such as Shelly BLU Button or Shelly BLU Motion to interact.
Additionally, Shelly devices can function as a BLE gateway, bridging Shelly BLU devices to your Wi-Fi network.
Is it possible to use the device without a hub?
Yes, Shelly devices (except for Wave devices) operate independently without the need for a hub. They connect directly to your Wi-Fi network, and you can control them via the Shelly Smart Control app, web interface, or through integrations with platforms like Google Home, Alexa, Home Assistant and Samsung SmartThings.
What is the triggering voltage for the digital inputs on the Shelly Plus Uni?
The digital inputs on the Shelly Plus Uni are active low, meaning they detect a logical "0" when the voltage drops below 1.5 V. When the voltage is above 1.5 V, the input is considered inactive. This configuration allows for reliable integration with various sensors and switches.
How can I integrate the Shelly Plus Uni with my existing smart home system?
The Shelly Plus Uni is designed for seamless integration with various smart home platforms. It supports protocols such as MQTT, HTTP/HTTPS, WebSocket, and Webhooks, allowing for compatibility with systems like Home Assistant, OpenHAB, and others. Additionally, it can be controlled via the Shelly Smart Control app and is compatible with voice assistants like Alexa and Google Assistant.
Can the Shelly Plus Uni control devices with dry contact outputs?
Yes, the Shelly Plus Uni features two solid-state relay outputs (OUT1 and OUT2) that are potential-free (dry contacts). This allows it to control devices without supplying voltage, making it suitable for various applications where isolated switching is required.
Is it possible to use the Shelly Plus Uni for monitoring tank levels in applications like RVs or campers?
Yes, the Shelly Plus Uni can be utilized for monitoring tank levels by interfacing with analog sensors. Users have successfully implemented it to measure water levels in fresh, gray, and black tanks by reading voltage levels through the analog input and converting them to percentage values using custom scripts.
Suitable for low-voltage applications, Shelly Plus Uni brings smart functionality to your old appliances. 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. Powerful in functionality and adaptable to any setting, Shelly Plus Uni seamlessly integrates into your home, unlocking endless possibilities for smart innovation.
