The house I’m renting came with the S220 video doorbell (battery) already installed. Since the bell alone was not loud enough to be heard throughout the house, after searching a bit for compatible devices, I bought Minibase Chime.
Adding the chime in the app went without problems (I made another 2.4Ghz wifi network in the router), but no matter what I’ve tried, I cannot add the doorbell.
It always fails after the “press sync button” prompt with a useless message “Could not add device”. The doorbell works, the sync button responds with the beep, the ring starts blinking, but it always fails to pair.
The minibase is connected using 2.4ghz, I verified that in the router admin panel. But the doorbell just refuses to do so.
Oh and I can’t disable only the 5Ghz network (thanks, KPN) while leaving the 2.4ghz intact. It’s either both or nothing. My hunch is that the doorbell will always choose the 5ghz and then fails to use it.
According to my searches, this was a common problem with eufy doorbells for ages, one would assume it would be fixed.
Temporary Network Fix: Since your router (KPN) doesn’t let you disable just 5GHz, consider creating a hotspot on a second device (like another phone) and connect both the doorbell and the Minibase to that. Set it to 2.4GHz only if possible. Once they’re paired, you might be able to switch back to your main network.
Pair Doorbell to App First (if not already): Make sure the S220 is already added and working in the Eufy Security app before attempting to pair it with the Minibase. Some users report it won’t connect otherwise.
Distance Matters: Make sure the doorbell and the Minibase are close together when attempting the sync. Also, try turning off mobile data on your phone during pairing — this sometimes helps force the app to communicate more reliably over local Wi-Fi.
Eufy Support Workaround: In the past, some people had luck by removing the doorbell from the app entirely, doing a full reset, then adding the Minibase first and the doorbell second — kind of reversing the order.
You’re also right — Eufy devices can try to jump on the 5GHz band and silently fail. Eufy really should have a better fix by now.
If nothing works, I’d honestly consider contacting Eufy support and referencing the issue directly.
You said you made another 2.4 GHz Wi-Fi.
How many 2.4 GHz Wi-Fi networks do you have?
Also the SSID names for 5GHz and 2.4 they are not the same names correct…
Select the same Wi-Fi that the chime is connected to and also have your phone connected to that Wi-Fi also while attempting to connect the doorbell.
If if the doorbell will not connect to the Wi-Fi then I guess the last thing to try is to remove it from the app and hold down the reset / sync button for 10 seconds or more until you see the blue ring to start flashing rapidly.
Our internet provider in all its wisdom decided to not let people manage the networks independently. 5Ghz is always on and you can only add additional guest network, extra 2GHz network and extra 5GHz network. Those you can turn on/off individually, but the main 5GHz is always on. And I think that’s what’s confusing the doorbell.
I’ve spent another 4 hours trying to get that thing to work using the everything I could thing of, including the advice with mobile hotspot on an old A12 Samsung that supports only 2Ghz, but to no avail.
I’m >this< close to smashing that thing with a hammer and nailing its remains on the door frame as a warning to others.
Thanks. I’ve tried just about everything, even trying to scan through logs on the phone to see if there is some obvious error message from the app, but nothing worked.
It’s so frustrating, especially because there is no information what’s wrong, no error code, no details, nothing. Terrible design.
I really hate this thing. I’ll try support as you suggested and if that doesn’t help, I’ll just buy Ring.
