2 Google Twin Cam Flood not working

Community Member

Both used to work, but now both are not working. I removed both from my Google home. When I try to reinstall it FAILS. I tried factory reset and both Wi-Fi 2.4 and 5

it ties to use another nest device, but after a while it simply fails. Feel badly for support people. What a mess.  




For the last year or more, some (many) Google Nest customers have been having problems when they try to add a new Google Nest device to their existing network of Google Nest devices, and the install process attempts--and fails--to obtain the Wi-Fi credentials from another Google Nest device--the notorious "assisting device". And the install process never tells them which device was the "assisting device".

We haven't encountered the error, but some customers in this forum got past the problem by temporarily turning off all of their existing Google Nest devices until they got the new device installed. Other customers have temporarily created a new Google Nest "home", installed the new device in that "home", then removed the device from that temporary "home", added it to their regular "home", and then deleted the now-empty temporary "home". Both of these workarounds are intended to force the install process to let you enter or select the Wi-Fi network name (SSID) and password, rather than trying to obtain it automatically from another Google Nest device (and then failing).

Thanks for responding so quickly. I believe the problem is in part human error (i.e. me). I have 2 Twin Floods: One in my alley (which is up high) and one on my deck which I can easily reach. I saved the QR codes for both.

The one in the alley I have not had any luck reinstalling (although it did initially work). The one on the deck was working perfectly, but I decided to uninstall it  to see if that would help with the one in the Alley. The one in the Alley still was problematic, and then I could not reinstall the one on the deck. 
Today I decided to skip the QR code and simply use the product key. I was able to reinstall the one on the deck without a problem. 🙂 I suspect this is the issue with the one in the Alley as well. 
I am wondering if the problem all along was that I was using the incorrect QR code. 
Please note that in order to get to the product key you have to take the hex nut off (and then take a picture). THis is not safe for an old man working on a ladder. I am old...
My suggestion is that moving forward that the product key can be placed in a location that does not require removing anything.
Having said all of that I believe if I had followed instructions (properly saving QR code) I would not have had the issue.
