How I fixed lag and timed out cameras
I mentioned in a previous post that the most requested domain lookup on my network is security-app-eu.eufylife.com - with 4,000-6,000 lookups every 24 hours!
I blocked these domains (and all subdomains under them) on my home network:
Since blocking those, the cameras connect first time - every time. Compared to before, where it was pretty much 50/50 if the camera would connect or timeout.
I blocked these domains using using AdGuard - but you might be able to do it within your router.
Side effects:
the app/cameras aren't able to check for firmware updates anymore - so I'd have to unblock them every now and then to check for updates.
accessing the cameras outside of the house isn't possible, unless you can VPN into your home network.
I'm guessing cloud backup might not work anymore - if you're paying for this.
Comment:
In an ideal world, when you're on your home network, eufy would just connect directly to the HB/Cams instead of always trying to go through the internet first. Then we wouldn't have to block any domains and deal with the side effects.
