# SMLIGHT SLZB

> SMLIGHT SLZB is a built-in integration for Home Assistant. It has 27.9k installs sharing analytics and works locally.

SMLIGHT SLZB is a built-in integration that connects Home Assistant to SMLIGHT SLZB devices over the local network. It adds binary sensors for Ethernet, Internet, VPN and Wi-Fi status, along with sensors for chip temperatures, uptime, memory and filesystem usage, connection mode and firmware channel. Buttons restart the core or the Zigbee and Z-Wave parts, reconnect the Zigbee router, and put the radios into flash mode. Switches cover automatic Zigbee updates, disabling LEDs, LED night mode and VPN, and a light entity controls the Ambilight. Update entities track core, Zigbee and Z-Wave firmware, and a repair notice appears when the core firmware needs updating. An action plays an RTTTL melody on the device buzzer, and an option sets the Bluetooth scanner mode. Devices are found automatically on the network and set up in the UI, with a login if the device requires one.
