Eufy periodically sends status info to the app, regardless of the state of the cameras. So if it can’t connect, it will eventually flash the LED red and if you are watching the app, will put up an error that it can’t connect at the top of the app page.

What do 4redlightson RingDoorbell mean

When I do look at the camera feeds when the red light is on, everything appears to be fine and I havent been able to find anything in the user manual to explain the red light.

I have tried multiple ports and cables, and I have hit the reset button on the bottom of the unit and it still is doing the same thing

Sounds like its hung up trying to download an update. Might want to unplug it and see if that will cancel the update and restart itself.

Runway edge lighting is used to outline the edges of runways during periods of darkness or restricted visibility conditions. These light systems are classified according to the intensity they are capable of producing:

The red flashing LED means the homebase has dropped connection to either the router or the internet. If it’s alternately flashing red/blue, that means its doing an update.

So every once in a while, I’ll notice that the status LED on the front of my homebase turns red and then after a few minutes, turn back to blue. What’s even weirder is that this happens when I’m NOT actively looking at my camera feeds through the Eufy app or through HomeKit.

It won’t affect your ability to record unless the homebase loses power. As long as the cameras can contact the homebase, recording still takes place. It will mean that you can’t view that recording until the internet comes back and the app can make contact again.

When an instrument runway lighting is designed, the last 600 metres (2,000 ft), or one-half of the runway length available (whichever is less), are bi-directional. They look white to the pilot approaching from the short end of the runway, but to a pilot approaching from the other end, who would be landing or taking off in that direction, they are yellow to indicate that the runway is nearing the end.[1][3]

Mine does the samething from time to time. The only thing I can think of causing it is the Home base isn’t able to call home for what ever reason. Would be nice if someone from Eufy would pop in here and answer the question.

If no luck, may need to do a Factory Reset which would suck cuz you would need to add it back to the app and also your cameras back to the HB3 & all recordings will be lost. Don’t know what the procedure is, I think there’s a small reset hole on the bottom of the HB.

If it’s connected via Wi-Fi, hook up the ethernet cable to it. Maybe the update process had caused the Wi-Fi connection to break?

Any luck yet? I was pondering / thinking… If you have a hard drive installed, remove it and try to do a reboot or factory reset.

The majority of runway edge lights are clear or white,[2] but there are some exceptions to provide additional information to pilots in certain circumstances.

Also check the ethernet cable connection on your router and maybe connect it to another port on the rear of the router. Try restarting your router…

Many HIRL and MIRL systems have variable intensity controls, whereas the LIRLs normally have one intensity setting. At airports where there is a control tower, the tower will manage the lights to account for visibility and pilot preference, but some airports do not have control towers. These airports will have Pilot Controlled Lighting, or PCL, where pilots can adjust the lighting themselves by keying a microphone button a certain number of times.[1]
