Protocols
Zigbee is still better for big, practical device meshes today. Matter is better understood as an interoperability layer that can improve onboarding and cross-platform support, but it does not automatically replace Zigbee's mesh maturity.
Use Matter when
- You care about multi-platform support across Apple, Google, Amazon, or Samsung.
- You are buying newer devices that already have solid Matter support.
Use Zigbee when
- You want lots of sensors/plugs/lights with strong mesh behavior.
- You already have a good hub/coordinator.
Reality check
Matter does not fix bad Wi-Fi, weak border routers, or immature vendor firmware. Zigbee still wins a lot of boring reliability fights.
