- Does What’s Matter work with Apple Home, Google Home and Alexa?
- We have no What’s Matter page on file that names a smart home platform, so we do not name one here. Each product page lists the platforms its catalog record names, marked unverified until the maker’s own page confirms them.
- How do I add What’s Matter Matter devices?
- To add a Matter device from What’s Matter, power it on, open your smart home app (Apple Home, Google Home, Amazon Alexa, SmartThings or Home Assistant), choose to add a Matter device, and scan the device’s Matter QR code or enter its setup code. Each platform has its own requirements, such as a hub or a compatible speaker; the platform guides below list them. 9 of the 15 What’s Matter products we list use Thread, so they also need a Thread border router on your network. A device already set up in another app can join a second one with a pairing code from the first app (Matter multi-admin).

Counts are the What’s Matter listings this page shows, from MatterCatalog's records: CSA certificates on file, the Matter network each record names and the stores with a verified US link. Hubs come from our reviewed lists of Matter bridges and Thread border routers, each backed by the maker's own words. Certificate IDs and dates come from each record (a date marked * is the ledger model’s first certification day). Ledger counts are the certified models of the ledger vendors matched to this brand. A platform is named only where the maker’s own page names it.
