Comparison – SMLIGHT SLZB articles

Overview and comparison of models: SLZB-06, SLZB-06-no-poe, SLZB-06m, SLZB-06Mg24, SLZB-06p10, SLZB-06p7, SLZB-06p7U, SLZB-MR1, SLZB-MR1U, SLZB-MR2, SLZB-MR2U, SLZB-MR3, SLZB-MR4U.

Quick summary

  • M = Silicon Labs EFR32MG21 (often “best for ZHA”)
  • Mg24 = Silicon Labs EFR32MG24 (newer/more capacity)
  • p7 = TI CC2652P7 (often “best for Zigbee2MQTT”)
  • p10 = TI CC2674P10 (highest capacity in the 06 series)
  • U = USB-over-Ethernet passthrough (runs e.g. Z-Wave stick “as if it were locally”)
  • no-poe = Ethernet but without PoE support

Comparison – SLZB-06 series single-radio

All SLZB-06 have Ethernet/USB/Wi-Fi/BT + SLZB-OS (web UI, OTA, VPN etc.) as "platform", the difference is mainly in the radio chip.

Model Radio chip (Zigbee/Thread) Multiprotocol Max “end devices” (≈) “Best for” PoE USB passthrough (U) Comment
SLZB-06 TI CC2652P No up to 200 Zigbee2MQTT Yes (802.3af) No “Base” TI variant
SLZB-06-no-poe (In practice 06 variant) No No Good when you want RJ45 but not PoE
SLZB-06m SiLabs EFR32MG21 Yes up to 200 ZHA Yes No Multiprotocol is available, but HA generally advises against multiprotocol mode
SLZB-06Mg24 SiLabs EFR32MG24 Yes up to 350 ZHA Yes No More capacity than 06m
SLZB-06p7 TI CC2652P7 No up to 300 Zigbee2MQTT Yes No Good “TI choice” when you want larger networks
SLZB-06p10 TI CC2674P10 No up to 400 Zigbee2MQTT Yes No Highest capacity in the 06 series
SLZB-06p7U TI CC2652P7 Yes Yes Same “hub” idea but with USB-over-Ether net for external dongles (Z-Wave etc.)

Note: “Max end devices” above are guidelines that are often used in product overviews and may vary in real installations (topology, routers, traffic, firmware, environment, etc.).

Comparison – SLZB-MR series dual-radio

The MR series has two separate radio SoCs (one TI + one SiLabs) so you can run Zigbee and Thread in parallel (or e.g. ZHA + Zigbee2MQTT).

Model Radiochip 1 Radiochip 2 Max “end devices” (≈) Strength PoE USB passthrough (U) Comment
SLZB-MR1 SiLab's EFR32MG21 TI CC2652P7 up to 500 (200+300) Dual radio (flex) Yes No Good “MRI start”
SLZB-MR1U SiLabs EFR32MG21 TI CC2652P7 MR1 + USB-over-Ethernet Yes Yes Important: not PoE + USB-C at the same time (risk of damage)
SLZB-MR2 SiLabs EFR32MG21 TI CC2652P up to 400 (200+200) Dual radio (cheaper than MR1/MR3) Yes No “Mix” of 06 + 06m chip
SLZB-MR2U (MR2 class) (MR2 class) MR2 + USB-over-Ethernet (U concept) Yes Yes U suffix is ​​used for the passthrough variant
SLZB-MR3 SiLabs EFR32MG24 TI CC2674P10 up to 750 (350+400) Maximum capacity Yes No “Top model” in the MR overview
SLZB-MR4U TI CC2674P10 (Zigbee) SiLab's EFR32MG26 (Thread) Newer radio (MG26) Yes Yes MR updated generation (in addition to MR1–MR3)

Quick recommendation (how to “place” them)

  • Standard choice / affordable: SLZB-06 (200) or SLZB-06p7 (300) for Zigbee2MQTT; SLZB-06m/SLZB-06Mg24 if the customer runs ZHA.
  • Larger Zigbee networks: SLZB-06p10 (up to 400).
  • Zigbee + Thread simultaneously / two networks: MR series (MR1/MR2/MR3).
  • Need “remote USB” (Z-Wave stick on LAN): choose the U variants (e.g. SLZB-06p7U, MR1U/MR2U/MR4U).
