Aqara may be the first major hub manufacturer (or the only, as far as I can tell) to officially support Matter bridges, with this video confirming it will expose its Zigbee devices to other Matter controllers:
Agreed. I should’ve noted Mr. Tekippe’s response was soon after Kevin, the ASSA ABLOY representative, had discussed the official Matter specification for bridging to either Z-Wave or Zigbee.
“While it does, the other technologies–like you said Z-Wave, Zigbee, Thread–they’re not going to go away. They’re not going to be abandoned or left out there on the sidewalk. We’ll continue to support them: if you’re using Z-Wave in the Pro channel now, continue to do so if that feels right for you. And, as Michelle said: that’s the key thing. Matter is not trying to leave them behind: there’s a bridge specification. If you choose, you’ll be able to have those products in the future, through a Matter-to-Zigbee or Z-Wave Bridge, continue to work. So there’s no goal here for Matter to abandon existing ecosystems or leave those types of things behind. So, it’ll take time and while it does, manufacturers such as ASSA ABLOY will be loyal to our customers, we’ll continue to support those technologies, while we evolve Matter, and help you with your future products.”
Though, you wouldn’t need a bridge for Z-Wave / Zigbee products to continue work, e.g., Samsung’s presumed angle currently by enabling two active “devices” in its Hubs: a “legacy” hub and a Matter controller.
You’re right that Samsung hasn’t stated they’ll be adding any bridges. Yet at least one person at SmartThings has noted the importance of bridging (in an official SmartThings panel discussion FWIW), so a bit of either mixed signalling or Samsung themselves don’t know what they’ll do. That is, I don’t put it past Samsung to end up throwing in the towel for bridges permanently, but it’s a slight glimmer of hope they won’t try ST-only lock-in or some convoluted a-SmartThings-bridge-yet-annoyingly-non-Matter.
Funnily enough, I’d actually initially highlighted that section because “Thread integration” had also perked my ears, but I wasn’t sure what Samsung had initially promised before, either, haha.
