Shelly Plus UNI Controller Module for Wi-Fi Network

Shelly Plus Uni is a compact smart universal module featuring two potential-free relays, a pulse counter, one analog, and two digital inputs. It enables remote control of electrical devices via a smartphone, tablet, computer, or home automation system. Shelly Plus Uni can operate locally on a Wi-Fi network or be managed through a cloud-based automation system.

The Shelly Plus Uni module can be used, controlled, and monitored remotely from anywhere with internet access, provided the device is connected to a Wi-Fi router and the internet. Shelly Plus Uni includes a built-in web interface for device monitoring, control, and configuration adjustments.

Shelly’s smart home products support Amazon Alexa and Google Assistant virtual assistants. In addition to these, several other smart home systems/platforms are supported (verify compatibility per product). Shelly products connect to a wireless Wi-Fi network and do not require a separate home automation controller to operate.

Note, installation must be performed only by an authorized electrician.
