# System Nexa 2

> System Nexa 2 is a built-in integration for Home Assistant. It has 25 installs sharing analytics and works locally.

System Nexa 2 is a built-in Home Assistant integration that connects to System Nexa 2 devices over the local network. It adds lights, sensors and switches, and the switches cover settings such as 433 MHz, cloud access, the LED, the physical button and the relay. Home Assistant can find a device on the network by itself and offer to add it. Setup is done in the UI by entering the hostname or IP address of the device. The connection settings can be changed later without removing the device, and a diagnostics file can be downloaded to attach to a bug report.
