We installed the Nest hello wired doorbell today and all the connections worked great up until the connection to the Nest app.
I am using an iphone for set up, and have in the past successfully set up the nest thermostat in our home using the Nest app.
I tried all of the suggested troubleshooting including resetting the modem, resetting the device and resetting it up at least 10x or more today. Throughout the day I have received different codes when the Hello can not complete set up, NC021, NC009, NC029. I have turned on airplane mode to ensure I am using the same internet, I have tried factory resetting the device. I have connected the Hello to bluetooth successfully on my phone. I have ensured the NEST app is up to date in the app store, restarted the app and the device I am using to set it up.
I have read the responses to "Nest doorbell (wired) will not connect to nest app or other nest devices." I tried the suggestion of removing the doorbell and connecting it to a USB plug and moving it within inches of the thermostat and router. Neither of these options worked.
I have searched forums for other ideas, but I am loosing my mind at this stage, please help.
This may not apply but could there be a chance that new wired installs require the Google Home app now? I know the battery version 100% requires it but it wouldn’t surprise me if new wired installs needed it too now.
That 009 code has something to do with firewall or maybe Internet security settings. From your modem and/or router I would test removing any firewall or Internet security at all; bring it totally open and just eliminate any barriers at all (you can always reinstate the settings after). If the camera connects after that, then you have some information to work off of. If not and it were my situation, I would look at returning and buying a new one. It’s just way too many errors for my liking.
