Shelly Plus Uni is a small form factor smart universal module featuring two solid state relays with potential free contacts, pulse counter, analog and two digital inputs. It allows remote control of electrical devices via mobile phone, tablet, PC or home automation system. It can operate standalone on a local Wi-Fi network or it can also be controlled via cloud-based home automation services.

Shelly Plus Uni can be accessed, controlled, and monitored remotely from any place where the User has internet connectivity, as long as the device is connected to a Wi-Fi router and the Internet.

Shelly Plus Uni has an embedded Web Interface which can be used to monitor and control the device, as well as adjust its settings.


  • Healthy garden - make sure you water your plants only when needed by connecting a soil moisture sensor.
  • Water heater and pipes Monitor water level, flow, pressure, and temperature to prevent issues and maintain ideal conditions.
  • Pool automation - maintain pool health with sensors to track water flow, level, pH, chlorine, and temperature, ensuring a safe and enjoyable swim.
  • Motion-controlled lights - when connected to a PIR sensor, Shelly Plus Uni can trigger a relay to turn on the lights as soon as you step into the room.


  • Standard warranty (included in purchase price): 3 Years warranty through manufacturer due to device malfunctions when it is used in user manual described conditions.
  • While this is technically user-installable in many locales, we recommend consulting a licensed electrician to install automation components - in addition to being licensed to work with electrical devices, they are also familiar with local building codes.
  • Manufacturer's note: Each Shelly device emits heat under load. Do not combine two or more Shelly devices stacked on top of each other in a confined space. There must be a minimum distance of 1 cm between them to allow for airflow.
