SMLIGHT SLZB-07MG24
SMLight · SLZB-07MG24
The SMLIGHT SLZB-07MG24 is a USB Zigbee coordinator designed for use with Home Assistant, ZHA, and Zigbee2MQTT. It uses a Silicon Labs EFR32MG24 chip and a CP2102N USB-to-serial converter, a modern combination for home Zigbee 3.0 networks. Its compact form factor with an external antenna makes it especially appealing for servers, mini PCs, or virtual machines where you want strong coverage without taking up too much space around the USB port. Unlike SMLIGHT models such as the SLZB-06, this model is designed for USB use and does not include Ethernet or PoE. It is a solid choice if you want to set up or migrate a Zigbee network in Home Assistant without relying on a network coordinator. It can also be used with Thread/Matter-over-Thread firmware depending on the firmware variant, although for a stable setup it is normally used as a dedicated Zigbee coordinator.
✓ Pros

- Compatible with ZHA and Zigbee2MQTT

- External antenna for improved coverage
- A good option for Home Assistant on a mini PC or virtual machine

✗ Cons
- No Ethernet or PoE
