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).
