Aeotec Z-Stick 10 Pro vs Smlight SLZB-MR5U

The Smlight SLZB-MR5U is the more capable coordinator overall, with Ethernet, PoE and Wi-Fi connectivity, dual-network operation, Thread and Bluetooth proxy support, and dual external antennas. The Aeotec Z-Stick 10 Pro wins for Z-Wave users thanks to its Z-Wave 800 controller, but the SLZB-MR5U leads as a flexible, network-connected Zigbee and Thread radio.

Connectivity and radio flexibility. The SLZB-MR5U is a network coordinator (Ethernet, PoE, Wi-Fi) that runs dual networks with Thread and Bluetooth proxy but no Z-Wave. The Aeotec Z-Stick 10 Pro is USB-only and adds a Z-Wave 800 controller, but lacks Ethernet, PoE, Thread, dual-network and Bluetooth proxy.

The Smlight SLZB-MR5U can run two networks (such as Zigbee and Thread) at once, which the Aeotec Z-Stick 10 Pro cannot do, since the Z-Stick 10 Pro does not support Thread at all. That makes the SLZB-MR5U more versatile for mixed Zigbee and Matter-over-Thread setups.

Only the Aeotec Z-Stick 10 Pro, which includes a Z-Wave 800 controller plus a Zigbee coordinator. The Smlight SLZB-MR5U is Zigbee and Thread only, so a separate controller would be needed for Z-Wave.

Buy the Smlight SLZB-MR5U if you want a network-connected coordinator with dual-network Zigbee and Thread, Bluetooth proxy and dual antennas that you can place centrally for a robust mesh in Home Assistant. It has no Z-Wave.

Buy the Aeotec Z-Stick 10 Pro if you need Z-Wave and Zigbee in one USB stick for a cloud-free Home Assistant setup and do not require Thread or network placement.
