2026 verdict
Two compact USB Zigbee-and-Thread dongles, and the Smlight SLZB-07P10 wins on value and raw radio power: it is the more affordable unit, works as a Zigbee router, and pairs the high-power CC2652P10 chip with +20 dBm of transmit power for strong range in larger networks. It runs cleanly with Home Assistant, ZHA and Zigbee2MQTT once set up, with painless migration from another dongle. The Nabu Casa Home Assistant Connect ZBT-2 answers with genuine strengths of its own: it carries a higher owner rating and a stronger +4.16 dBi antenna, and as official Home Assistant hardware it is recognized automatically with no firmware step, where the SLZB-07P10 ships with outdated firmware you must flash first. Both are USB-only radios for a local Home Assistant. Choose the Smlight SLZB-07P10 for cheap, high-power Zigbee if you can flash firmware; choose the Nabu Casa Home Assistant Connect ZBT-2 for the smoothest, no-flash official setup.
