Shelly Plus Uni

R449.00

Shelly Plus Uni (the Device) 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.
