SMLIGHT SLZB-06M – A Zigbee 3.0 to Ethernet, USB, and WiFi Adapter with PoE Support, Works with Zigbee2MQTT, Home Assistant, ZHA

I've been using the SMLIGHT SLZB‑06p7 as a Zigbee 3.0 gateway for a few weeks now and it’s been rock solid. Setup was a breeze—plug it in via Ethernet or PoE, and it’s pre-flashed to go. In Home Assistant, it auto-connected, and the web dashboard makes firmware updates and protocol switching super easy.

Sometimes a product comes along that makes life much easier. This is one of them. I run Home Assistant via a virtual machine running on a Synology NAS. A Sonoff USB dongle connected to the NAS was my Zigbee coordinator. Once I had the Sonoff up and running, I was able to forget about it, because it just worked. The problems started whenever I had to unplug it from the NAS. Inevitably, the USB connection was forgotten by the Synology software and I had to remember how to turn it back on again, or the USB drivers failed. When the drivers failed I was forced to SSH into the NAS and use command line entries to download, and hopefully install, the correct USB drivers. Because this only happened every couple of years, it was always a challenge to remember how to fix the issue. I have the SMLIGHT connected directly into one of my network switches, and it's powered via POE. There are no drivers to worry about and it has a very nice web interface that allows complete control of the device. In my opinion, one of the best features of the SMLIGHT is its ability to spoof the MAC address of the Sonoff dongle. Once the MAC address of the Sonoff was entered into the web interface of the SMLIGHT and it was rebooted, all of my devices just assumed that the SMLIGHT was the Sonoff, so I didn't have to repair any of them. Easy-peasy. The Sonoff was/is a nice piece of tech., but the SMLIGHT takes things to another level.

This is a great antenna for my Home Assistant system. I love that I could use POE and ethernet to connect it to my system and I haven't had any lag or issues with controlling the many Zigbee dimmers in my system.

I bought this for integrating Zigbee devices with my Home Assistant server and it has been great. Currently, it is running ~50 Zigbee devices without any issues. The worst lag I get is about 1s from a PIR sensor registering motion to the corresponding light turning on. There are plenty of hops along the way, so 1s is fairly quick and I cannot complain. Installation was easy and the range has been great. This is definitely one of the better options for the price point.

Software is a little "quirky", but the ZigBee functionality is great and integrates well in Home Assistant! I seem to always have issues on the Security page, where things like input fields are requiring values when the feature is disabled, enabling certain features appear to remain disabled when they're not, and setting web UI password breaks minor integration on Home Assistant. Seems significant, but it's not that bad, and the core ZigBee functionality runs perfectly, so it's still well worth it.

Easy to adopt and set up in Home Assistant with Z2M. Worked great with no lag- lights turn on instantly. Seems well build and the price was comparable with other hubs I looked at. Third Reality Smart Plugs, Lutron wall switch, Google Home and a bunch of other devices easily connected since it's compatible with any zigbee device. This was a good purchase for me.

It loses contact with devices that worked reliably with another coordinator. Migration did not work in Home Assistant. Devices must be very close for discovery. It seems to be vulnerable to out-of-band interference. After being powered down for an hour, it permanently lost contact with all Zigbee devices.

I flashed this with the Matter firmware to run a few Matter devices with Home Assistant. Works as designed, I can control my matter devices. The flashing process is quite simple.

Après 3 mois de test avec Home Assistant, aucun soucis. C'est 4 fois mieux que la version USB, je peux mettre le coordinateur où je veux

Ich nutze den SMLIGHT SLZB-06 seit mehreren Wochen in meinem Smart-Home-Setup als ZigBee-Koordinator in Kombination mit Home Assistant OS. Nach diversen Tests mit ConBee und Sonoff-Dongles kann ich sagen: Der SLZB-06 spielt technisch in einer anderen Liga. Schon die Hardwarequalität überzeugt – das Gehäuse ist kompakt, sauber verarbeitet und wird nur handwarm. Der verbaute EFR32MG21-Chip arbeitet sehr stabil, die Reichweite ist beeindruckend und die Mesh-Performance deutlich besser als bei USB-Dongles. Besonders angenehm ist die Flexibilität bei der Anbindung: Der SLZB-06 kann über Ethernet, USB oder WLAN betrieben werden, wahlweise sogar mit PoE-Versorgung, was in professionellen Umgebungen richtig praktisch ist. In meinem Setup läuft das Gerät per PoE direkt am Switch – kein zusätzliches Netzteil nötig, keine Signalabbrüche. Die Integration in Zigbee2MQTT war innerhalb weniger Minuten erledigt, die Firmware ließ sich problemlos updaten. Auch bei vielen gleichzeitig verbundenen Geräten (aktuell über 60 Sensoren und Aktoren) bleibt die Verbindung stabil, ohne Lags oder Aussetzer. Die Weboberfläche ist übersichtlich gestaltet, zeigt Signalstärken, Firmwarestände und Logs klar an. Besonders positiv: Der Hersteller liefert regelmäßig Firmware-Updates und dokumentiert Änderungen transparent. Fazit: Der SMLIGHT SLZB-06 ist derzeit einer der besten ZigBee-Koordinatoren am Markt. Hervorragende Reichweite, stabile Performance, flexible Anschlussmöglichkeiten und PoE-Support machen ihn zur idealen Lösung für alle, die ihr Smart-Home zuverlässig und professionell betreiben wollen. Absolute Empfehlung für fortgeschrittene Anwender und Technik-Enthusiasten.

Funcionó excelente con HA. Sin problemas para detectar todo tipo de dispositivos. Recomendado totalmente

Se sei un tecnico con un homelab, questa è la roba migliore che puoi prendere. Fantastica

For way too long, I have struggled with Zigbee USB dongles. They are unreliable and disconnect too often. This is a brilliant device, easy to set up with a great interface. Highly recommended.
