Smlight SLZB-07 MG24 vs Smlight SLZB-07P10

The Smlight SLZB-07 MG24 is the better overall pick because it is the more affordable of the two and gives up nothing in features. Both dongles are Zigbee 3.0 coordinators and routers, both act as Thread border routers, both share the same +20dB amplifier and external antenna, and both work with Home Assistant, ZHA and Zigbee2MQTT. With the specs tied, price decides it in favor of the SLZB-07 MG24.

The radio chip. The Smlight SLZB-07 MG24 is built on the Silicon Labs EFR32MG24, a newer part with more memory and processing headroom for big Zigbee networks and solid Thread support. The Smlight SLZB-07P10 uses the Texas Instruments CC2652P10, the high-power chip with the longest track record in Zigbee2MQTT setups. Everything else, from the Zigbee version to the amplifier gain and the antenna, is identical.

Yes, both the Smlight SLZB-07 MG24 and the Smlight SLZB-07P10 can run as Thread border routers once you flash the corresponding firmware. Neither works as a Matter bridge, so they expose Thread devices to your controller rather than translating existing Zigbee gear into Matter. Flashing Thread firmware is the fiddliest part of either dongle, so plan for it.

No. Both are USB-only, Zigbee and Thread devices with no Z-Wave controller, no Ethernet port, no PoE and no Wi-Fi. If you need Z-Wave or want the coordinator away from your server on a network cable, look at Smlight's SLZB-06 line or a dedicated Z-Wave stick instead of either of these two.

Buy the Smlight SLZB-07 MG24 if you want the cheapest way into a modern, Thread-capable Zigbee coordinator for Home Assistant and are comfortable flashing firmware before use. Its EFR32MG24 chip has the memory and speed headroom for a growing mesh, and it is also the lighter of the two at 9g.

Buy the Smlight SLZB-07P10 if you would rather build your mesh on the Texas Instruments CC2652P10, the high-power chip most veteran Zigbee2MQTT users know well. You get the same +20dB amplifier, external antenna and Thread capability as the MG24 version, just from a different silicon family and at a slightly higher price.
