Im in Australia with S380 Homebase (3) and I bought a dual camera add-on also.
My current settings are;
I’ve tried to connect my doorbell but just keeps asking for me to set up a home base before adding the doorbell.
Im as frustrated as everyone else.
No. You either don’t have the mobile app version 4.6.4 or the HB3 version 3.1.9.5 or both. Multiple people in the thread confirmed you need both for it to work.
If you check reddit.com/r/eufy you will see some people using VPNs to update from other regions, although I would caution that you may get different regional firmware.
iOS and Android stores also have different approval policies/queues etc so it may just be that the app has to be approved by Apple in each region - it’ll get there 
If you are impatient like me, email support@eufylife.com and open a ticket. Explain to them you do not want to wait and would like the firmware pushed. Provide them the serial number of the HB3 you own. When they confirm that they will push it within “24-48 hours” it will actually come way sooner than that, like minutes.
There is nothing they can do about 4.6.4 since google/apple owns that schedule. However if you are like me, and already had 4.6.4 and no 3.1.9.5 then I suggest you do the above. It worked for me and I can finally use my doorbell!!
Hi, every time I contact eufy they said, it will be ready in 3 days its been 2 weeks and now they do not even telling the truth. I am wondering if the solution would be using legal advice to find out if at lease we can get our money back ($ I purchased homabase 3 and dual 2k doorbell cam$)
Eufy shame on you and your lies
Got another app update now 4.6.5 but still no update on firmware. Getting ridiculous!
That’s odd. I got my firmware update almost a week before I received the app update. I’m in the U.S., so that might be the reason, if you’re in a different country.
San Diego, CA, got the IOS App update several days ago. Got Homebase 3.1.9.5 update about 10 minutes ago. Dual Cam doorbell paired with Homebase 3 easily and is set up and working. Took less than 5 minutes. I do not own a Homebase 2 so was a bit worried, but everything went very smoothly!
Thanks!
Finally got the update here in Aus. Time to test out the doorbell now!
Hi. Anyone from Australia got it working?
Can’t wait for the good news
Thanks
Hi there. Just wondering if you got the camara working with the home base 3.
Thank you
Yes, I got it working yesterday after HB3 firmware was updated to 3.1.9.5
I tried many times to connect my duel doorbell to hb3 but it keeps asking for adding home base first!!
I’ve already contacted hb3 to Rudy security app but it didn’t recognize it.
Firmware has updated to 3.1.9.5 for me in Australia now and Doorbell camera is connected to my system now!
At last!! I am all paired up and have a doorbell that works! Now to see if the chime can be set up 
lol
@Pete158 I know you do not work for Eufy but your knowledge has been wonderful, thanks mate!
No worries - at least we’re all getting what we expected (finally)
Now we just need ChromeCast functionality back 
(FYI I have the USB dongle/chime that was working on my HB2 with the T8213, and it works with the HB3 fine - although it does stick out horizontally so is probably due a redesign!)
Yeah when I was installing the Chime there I noticed it said ‘Chime for HB2’ and I expected the worst. Fortunately everything is good although I do think there is a 1-2 second delay to both doorbell ring and notification on my phone. Hoping that improves with time.
Finally!!
Everything went will and I’ve connect my duel doorbell to hb3
Good to see its finally here and working but its now broken the known faces notification so iam now getting notified of everything.
1 step forward 2 back.
I got it sort of working.
Anyone experiencing the same?
