Mesh Network Traps

• Battery devices don't route — only mains-powered devices extend mesh
• Mesh needs routers every 10-15m — one coordinator alone has limited range
• Adding routers requires rebuilding routes — devices don't automatically find new paths
• First devices paired become mesh backbone — pair routers before sensors

Coordinator Issues

• Only one coordinator per network — two coordinators create two separate networks
• Coordinator stick placement matters — USB extension away from computer reduces interference
• Coordinator migration loses all pairings — backup before switching hardware
• Some sticks need firmware flash — Sonoff, CC2531 don't work out of box

WiFi Interference

• Zigbee shares 2.4GHz spectrum — WiFi channels overlap with Zigbee channels
• Zigbee channel 11 = WiFi channel 1, Zigbee 25 = WiFi 11 — pick non-overlapping
• Default Zigbee channel 11 often worst — conflicts with common WiFi defaults
• Changing Zigbee channel requires re-pairing all devices — choose carefully initially

Compatibility Issues

• "Zigbee compatible" doesn't mean interoperable — some devices only work with their hub
• Xiaomi/Aqara devices drop off generic coordinators — need specific handling
• Tuya Zigbee often requires their gateway — may not pair with Zigbee2MQTT
• Check device compatibility list before buying — not all Zigbee is equal

Pairing Problems

• Pairing mode timeout is short — be ready before enabling
• Factory reset required if previously paired — hold button 5-10 seconds
• Distance during pairing matters — pair close to coordinator, move after
• Some devices need multiple reset attempts — keep trying

Groups vs Binding

• Groups: coordinator sends one command to all — requires coordinator online
• Binding: direct device-to-device — works without coordinator, lower latency
• Binding a switch to bulbs survives coordinator reboot — groups don't
• Not all devices support binding — check before planning automation

Battery Devices

• Battery sensors sleep aggressively — commands only received on wake
• Check-in intervals vary by device — some wake every hour, others every few seconds
• Reporting thresholds affect battery life — frequent updates drain faster
• Replacing battery sometimes requires re-pairing — device forgets network

Common Failures

• Device shows online but doesn't respond — try power cycle, check routing
• Intermittent responses — mesh too sparse, add routers
• Delayed commands — routing through many hops, add closer router
• New device won't pair — network in wrong mode, coordinator issue, or device not reset
