Using Nest WiFi Point as speaker only with a different router
I was having too many problems with my Google Nest Mesh WiFi Setup (main router + 2 points/speakers). So I am now on TP-Link Deco for my main wifi router.
But I will still like to use Nest WiFi Points as speakers only.
I have removed the devices from my Google Home app. And I have done factory reset (by physically holding down the button at bottom) on the points.
Now, when trying to add as new device in Google Home, it detects the new devices, but when I enter the 8-length alphanumeric "Setup Code", nothing happens. It just goes back to "scan qr code" without any kind of message or error code. It seems like even if I type garbage in that Setup Code text box, same thing happens. So it looks like it is not recognizing the setup code and I have checked mulltiple times that I am entering it right.
Is it not possible to use Nest WiFi point as a speaker only with another router completely standalone with no primary Google router to talk to?
