It is a compact but high-power USB Zigbee coordinator on the Texas Instruments CC2652P10 chip that owners find no-drama with Home Assistant once its firmware is flashed. The two radios cover different protocols, so they are not interchangeable: the Nabu Casa Home Assistant Connect ZWA-2 is a dedicated Z-Wave 800 controller with a higher owner rating and a slightly stronger antenna at +3.38dBi against +3dB, and it delivers the standout Z-Wave range Nabu Casa is known for. Both are USB radios for Home Assistant. Go with the Smlight SLZB-07P10 for a cheap, powerful Zigbee/Thread coordinator; go with the Nabu Casa Home Assistant Connect ZWA-2 for dependable Z-Wave.

Frequently Asked Questions

Should I pick the Smlight SLZB-07P10 or the Nabu Casa Home Assistant Connect ZWA-2?
