4. Setup Instructions

4.1 Powering the Device

The SLZB-06 series offers flexible power options:

  • USB Power: Connect the device to a 5V/200mA USB power source using the provided USB Type-C cable.
  • PoE Power: For models supporting PoE (Power over Ethernet), connect an Ethernet cable from a PoE-enabled switch or injector (IEEE 802.3af standard) to the device's RJ45 port. This eliminates the need for a separate power supply.

Important USB-C Power Note:

  • Do not use Type-C to Type-C cables for power.
  • Avoid using fast chargers, as they may provide incompatible voltage/current.

4.2 Connecting to Your Network

The device supports multiple connection methods:

  • Ethernet (LAN): Connect an Ethernet cable from your network switch or router to the device's RJ45 port. This is the recommended method for stability and speed.
  • USB: Connect the device directly to your Home Assistant server via a USB cable.
  • Wi-Fi: Configure the device to connect to your Wi-Fi network. This is useful when Ethernet or USB access is not convenient.

7. Troubleshooting (FAQ)

Q1: Do these coordinators work with Zigbee2MQTT and ZHA?
A1: Yes, all models are designed to work seamlessly with both Zigbee2MQTT and ZHA.
Q2: Is there a significant benefit to using SLZB-06P7 (CC2652P7 SoC) over SLZB-06 (CC2652P SoC)?
A2: If your Zigbee network will not exceed 200 end devices, the performance difference between CC2652P and CC2652P7 is minimal. Both chips use the same Cortex M4F 48Mhz processor; the primary difference is RAM capacity. For larger networks, the increased RAM of the CC2652P7 might offer slight advantages.
Q3: Can I connect multiple adapters to the same instance of Home Assistant?
A3: Yes, you can. This typically requires running two or more instances of Zigbee2MQTT. Refer to the product manual or online resources for detailed instructions on multi-coordinator setups.
Q4: Can I use a “passive” 24V PoE injector?
A4: No, the adapter supports the active PoE standard IEEE 802.3af. Only PoE routers and injectors compliant with this standard will work correctly.
Q5: Is it possible to use the device in Wi-Fi mode?
A5: Yes, you can switch the device to Zigbee-to-Wi-Fi mode and connect it to your existing Wi-Fi network.
Q6: Are there any delays in Zigbee communication when using Ethernet?
A6: No, Ethernet (100Mb) is significantly faster than the typical baud rate (115k) used for USB serial connections, so you should experience no delays.
Q7: Can I place the SLZB-06 in a different room from my Home Assistant server and connect via Ethernet?
A7: Absolutely. A key advantage of the SLZB-06 is its ability to be located independently of your server, allowing for optimal Zigbee network placement. This even supports remote connections to different buildings.

9. User Tips

  • Choosing Your Model: If your Zigbee network is expected to have fewer than 200 devices, the SLZB-06 (CC2652P) offers excellent performance without the need for the higher-spec SLZB-06P7 (CC2652P7).
  • Optimal Placement: Leverage the Ethernet or Wi-Fi connectivity to place your Zigbee coordinator in a central location for the best signal coverage, rather than being restricted by your Home Assistant server's location.
  • PoE Compatibility: Always ensure your Power over Ethernet (PoE) source is active and adheres to the IEEE 802.3af standard to avoid compatibility issues.
  • Multi-Coordinator Networks: For extensive smart home setups or multiple buildings, consider using multiple coordinators with Zigbee2MQTT to expand your network's reach and reliability.
