1. Build a strong mesh network
   Zigbee is a mesh protocol — mains-powered devices (smart plugs, bulbs, in-wall switches) act as routers and extend your network. Battery devices (sensors, buttons) don't. Aim for a good spread of mains-powered devices throughout your home so signal has multiple paths to travel.

2. Avoid Wi-Fi channel overlap
   Zigbee operates in the 2.4GHz band, same as Wi-Fi. If your Zigbee network feels unstable, set your Wi-Fi router to channels 1, 6, or 11 and pick a Zigbee channel that doesn't overlap (e.g. channel 25 or 26).

3. Don't overload a single hub
   Most Zigbee coordinators can handle 50-200 devices depending on hardware, but performance degrades if you cram too many onto one hub without any routers. Spread devices out and let mains-powered ones do their job as repeaters.

4. Keep your coordinator central and elevated
   Place your Zigbee hub/coordinator in a central location, elevated off the floor, and away from metal objects, mirrors, or thick concrete walls that can block signal.

5. Update firmware regularly
   Zigbee firmware updates often fix bugs related to pairing, range, and interference. Check your hub manufacturer's app periodically for updates.

6. Use pairing correctly
   Always factory reset a device before pairing it to a new network, and pair devices one at a time and close to the coordinator initially — you can move them to their final location afterward once they've joined the mesh.

7. Group similar devices logically
   Use rooms/zones and groups in your hub software so scenes and automations are easier to manage and troubleshoot later.

Following these basics will get you a Zigbee network that stays online and responsive instead of one that needs constant re-pairing. Happy to answer questions if anyone's running into specific issues.
