Nabu Casa Home Assistant Connect ZBT-2 vs Smlight SLZB-07 MG24

The Smlight SLZB-07 MG24 wins on value, costing less and adding Zigbee router support plus a stronger amplifier. The Nabu Casa Home Assistant Connect ZBT-2 wins on polish and reputation, carrying a higher owner rating and better antenna gain as the official Home Assistant-branded radio.

Price and pedigree versus raw specs. The Connect ZBT-2 is Nabu Casa's official hardware, built for seamless recognition by Home Assistant and backed by a stronger owner rating. The SLZB-07 MG24 costs less and adds Zigbee router capability (letting it extend an existing mesh) along with a higher amplifier gain rating.

Each wins on a different radio metric. The Connect ZBT-2 has the stronger antenna gain figure of the two, while the SLZB-07 MG24 posts the higher amplifier gain. Both use external antennas and both function as Thread border routers, so real-world range will also depend on placement.

Yes, that is one of its advantages over the Connect ZBT-2. The SLZB-07 MG24 can run in router mode to extend the range of an existing Zigbee network, a feature the Connect ZBT-2 does not offer since it is built purely as a coordinator.

Home Assistant users who want the official, best-supported dongle with the highest owner satisfaction and strong antenna performance should choose the Connect ZBT-2, accepting the higher price for that reliability.

Buyers on a tighter budget, or anyone who wants the option to run the dongle as a Zigbee router down the line, will get more for their money with the SLZB-07 MG24.
