Coordinator placement matters
A clean coordinator location often changes more than repeatedly re-adding devices.
This page is for the frustrating middle ground where devices pair at first but do not stay reliable. The goal is to help readers understand the network shape, coordinator placement, and interference path before they start randomly re-pairing everything.
A clean coordinator location often changes more than repeatedly re-adding devices.
A larger device count can expose weak links that were not obvious on day one.
The Zigbee path should be thought about alongside Wi-Fi and the rest of the smart-home layout.
These checks help you tell the difference between one weak device path, one bad area, and a broader coordinator or interference problem.
Start with pairing if new devices cannot join. Start with interference and coordinator layout if devices join once but do not stay healthy.
