SLZB-U2L — your USB radios, on the network
Meet the SLZB-U2L USB-to-Ethernet Bridge: put Zigbee, Z-Wave, Thread, LoRa and 433 MHz dongles on LAN, Wi-Fi or PoE — with 2-to-1 USB aggregation, WireGuard, DDNS and OTA built in. Rolling out now.
Every smart home hits the same wall eventually: the radios want to live where the mesh needs them, and the server wants to live where you keep it. USB extension cords are not an answer.
The SLZB-U2L is. It is a modular USB-to-Ethernet bridge that makes your USB smart-home radios available across your LAN or Wi-Fi — so the Zigbee coordinator sits in the hallway ceiling where coverage is perfect, while Home Assistant stays in the rack where it belongs.
See the full picture on the SLZB-U2L product page.
What it does
- Two USB devices at once — run a Zigbee coordinator and a Z-Wave stick side by side, over the network.
- 2-to-1 USB aggregation — or expose both dongles through a single physical USB port on your host.
- LAN, Wi-Fi or PoE — RJ45 10/100, 2.4 GHz Wi-Fi, or the optional PoE module for one-cable installs.
- SLZB-OS on board — WireGuard VPN, DDNS, OTA updates, per-LED control (yes, including the RJ45 port LEDs) and a multilanguage web UI.
- ESPHome supported — USB host interface, USB-UART passthrough, Bluetooth Proxy — if you would rather run open source end to end.
What plugs into it
Tested and verified with the radios people actually use:
| Category | Devices |
|---|---|
| Zigbee / Thread | SLZB-07, SLZB-07P7, SLZB-07P10, SLZB-07MG24 |
| Z-Wave / Long Range | popular Z-Wave USB controllers and sticks |
| Everything else | any dongle on CH34X, CH340, ESP_JTAG, STM32_VCP, CDC_ACM or CP210X |
That last row is doing a lot of work — those six chipsets cover nearly every hobbyist radio ever sold.
Where it fits
- Run a Zigbee coordinator over LAN instead of a USB cable to nowhere.
- Combine Z-Wave + Zigbee sticks into one networked hub.
- Add a Thread/Matter dongle for the Google/Apple side of the house.
- Deploy LoRa or 433 MHz receivers for long-range and legacy RF sensors.
- Put a bridge in a remote site over WireGuard — and when the 4G/LTE uplink module lands, even wired internet becomes optional.
