eufy Floodlight Cam E340 Lights Not Working? Here’s How to Fix It
The floodlights on your eufy Floodlight Cam E340 turn on automatically with motion, or you can control them in the app. If they won’t light, check the app settings, motion and the power.
What This Problem Means
If your eufy Floodlight Cam E340 is showing this fault, working through the checks below in order resolves it in the large majority of cases. Each step is safe to try yourself and follows eufy’s official guidance.
Common Symptoms
- Lights don’t come on with motion
- Can’t toggle the lights in the app
- Lights stay off (or stuck on)
- Camera works but lights don’t
Safe Checks You Can Try
1. Check the light settings
In the eufy Security app, confirm the floodlights are enabled and try switching them on manually.
2. Confirm motion detection is on
Motion-activated lighting only works when detection is enabled and you’re not in Disarmed mode.
3. Check the schedule
Make sure the lights aren’t limited to certain hours or set to daytime-off only.
4. Check the power
The Floodlight Cam is hardwired — confirm the correct breaker is on and the wiring is secure.
5. Restart the camera
Turn the power off at the breaker for 30 seconds, then back on and let the camera restart. Restart your router by unplugging it for 30 seconds. This clears most temporary glitches.
6. Update the firmware
A firmware update in the eufy Security app can resolve lighting-control bugs.
