new error codes?

Had a Nest wired gen1 that was damaged, so I ordered a gen2 to replace it. Receiving cryptic error codes that don't correspond to anything in Google documentation. Been trying for over a month to get the thing working.

  1. Again, I had a nest doorbell working just fine on this network, in this spot, a month ago
  2. same iphone that I originally set up the doorbell with Google Home
  3. Poor network signal (cheaper wifi radio in gen2?), so I tried using my phone hotspot as the wifi network and successfully connected, only to learn that the network is hard-tied to the doorbell during setup and the only way to change it is to reset and start over (wtf!?)
  4. Ordered an additional mesh wifi to increase signal strength, it's great now
  5. doorbell soft reset, hard reset, multiple times
  6. phone airplane mode on/off, cellular on/off, phone power off/on, private ip off, private relay off
  7. updated google home app
  8. new Home in google home

Received various errors including 12.1, 15.5, 18.1 which do not correspond to any information I can find online, and which provide no helpful detail. Appreciate any wisdom from others who have suffered through this.

Hi chris-nest-wtf,

Thanks for posting in the community. I'm sorry to hear your Nest wired Gen 2 isn't connecting to the Google Home app. That's definitely frustrating, and we'll work to get it resolved.

Before we begin, please ensure your phone or tablet is within 2-3 meters (6-10 feet) of the Nest device.

Here are the troubleshooting steps we can try:

Basic Checks:

  1. App Restart: Close and reopen the Nest app or Google Home app.

  2. Device Restart: Restart your phone or tablet.

  3. Nest Device Restart: Restart your Nest wired Gen 2.

  4. Airplane Mode Toggle: Enable Airplane mode on your phone or tablet, then manually turn Bluetooth and Wi-Fi back on.

Advanced Troubleshooting:

  1. Alternative Device: Try using a different phone or tablet for the pairing process.

  2. Network Restart: Restart your router, Wi-Fi extender (if used), and modem.

  3. Nest Device Factory Reset: Perform a factory reset on your Nest wired Gen 2.

  4. Mobile Hotspot Test: Temporarily create a mobile hotspot on a different phone and connect the Nest device to that hotspot. This helps isolate network issues.

Home Structure Troubleshooting:

  1. New Home Structure Test: Create a new "Home" in the Google Home app and attempt to pair the Nest device there.

    • If successful and you prefer the new Home: You can delete the old Home and reset and re-add all devices to the new Home.

    • If successful and you prefer to keep the old Home: Remove all devices from the old Home, ensure all devices are on the same network (check network settings in Google Home), and then re-pair the Nest devices.

Please try these steps and let me know the results.

I look forward to your response so we can get this resolved.

 

Regards,

Kevin
