Universal smart Wi-Fi module Shelly Plus Uni

Shelly Plus Uni is a compact universal module that combines two dry-contact relays, one analogue input, two digital inputs and a pulse counter in a single WiFi device. It is designed for integrators who need maximum flexibility in a small form factor.

The two dry-contact outputs can switch up to 28 VDC or 24 VAC, and precise voltage measurement is done over two ranges (0-15 VDC and 0-30 VDC). It works standalone on the local WiFi network or via cloud services, and can also act as a WiFi signal extender or Bluetooth gateway for other Shelly BLU devices.

It is suitable for reading pulse-output water or gas meters, for integrating existing analogue sensors into a smart home system, or for controlling two separate low-voltage circuits from a single compact module.

Practical use cases

• Connects to external analogue or digital sensors (temperature, dry contacts, pressure) and integrates them into the Shelly ecosystem.
• Useful for automating older equipment that has no connectivity of its own, by reading its status and sending it to the app.
• Can control small loads through its digital outputs, for example activating a doorbell or an auxiliary relay.
• Recommended for custom automation projects where non-standard sensors or equipment need to be connected.

Technical specifications

Compact and versatile, Shelly Plus Uni covers integrators' complex I/O needs in a single module, without requiring a separate hub to operate.
