Shelly Plus Uni

Shelly Plus Uni

The Shelly Plus Uni brings smart functionality to legacy appliances and low-voltage applications that standard smart switches cannot address. This versatile device supports 8-24VAC, 9-28VDC, and 5VDC power supplies, enabling automation of doorbells, intercoms, irrigation systems, and other low-voltage equipment throughout your property.

Featuring two digital inputs and one analogue input, the Shelly Plus Uni captures data from a wide variety of sensors and switches. Support for 1-Wire sensors including a single DHT22 and up to 5 DS18B20 temperature sensors enables comprehensive environmental monitoring. Compatibility with most Arduino sensors opens up extensive possibilities for custom sensing applications using the digital or analogue inputs.

The pulse counting feature provides precise readings from energy meters, gas meters, water meters, and other devices that output pulse signals, enabling monitoring of utility consumption that would otherwise require specialised equipment. The ESP32 processor delivers immediate response while the device functions as a Wi-Fi range extender and BLE gateway. Advanced features include scripting, webhooks, MQTT, WebSocket, HTTPS, UDP, TLS, and custom certificates. Works with the Shelly Smart Control app, Amazon Alexa, Home Assistant, and other platforms.
