Troubleshooting
If smart lights keep dropping, the problem is usually protocol fit, mesh depth, or bad power habits, not just the bulb itself.
Fast diagnosis
- Wi-Fi bulbs: check RSSI, channel congestion, and 2.4 GHz stability.
- Zigbee bulbs: check that you have enough mains-powered repeaters and that the bulbs are not on flaky dimmers.
- Thread/Matter bulbs: confirm the border router and controlling app are stable.
Most common fixes
- Stop cutting power at the wall if the bulb expects constant power.
- Use smart switches for switched circuits instead of smart bulbs where possible.
- For Zigbee, add one or two solid repeater devices before blaming the bulbs.
- For Wi-Fi bulbs, move cheap always-on IoT gear off your main SSID if the network is overloaded.
