NestGridVerified fixes and compatibility checks for smart home devices — by protocol, hub, and date, not forum guesswork.

Protocols

Reference and changelog content explaining the standards that determine whether devices can work together: Matter, Zigbee, Z-Wave, and Thread, including hub and border-router requirements and cross-ecosystem interoperability (Apple Home, Google Home, Alexa, SmartThings, Home Assistant). This group covers concepts and spec-version changes (e.g. what Matter 1.6 Joint Fabric changes, Matter over Thread vs Matter over Wi-Fi) rather than device-specific fixes or device-specific compatibility claims. It exists so a troubleshooting entry or device profile can link to a stable explanation instead of re-explaining the standard each time. Excludes step-by-step fixes (Troubleshooting) and device-by-device verification (Devices).

This section explains protocol behavior generally. For a specific device's status, see Devices; for a symptom fix, see Troubleshooting.
