SMLIGHT SLZB-06

Quick verdict

The SLZB-06 solves the biggest problem with USB coordinators: placement. Run an ethernet cable to wherever your Zigbee coverage needs to be best, not wherever your server sits. It's more hardware and cost than casual users need, but for larger homes it's a game changer.

Standout: Ethernet and PoE deployment let you place the coordinator where the RF reality is best instead of where your server happens to sit.
