Can’t connect 2nd thermostat to the app

I’m trying to connect a second Nest thermostat (2nd one is a 3rd gen learning thermostat, not sure about the first one) to a home but I keep getting error code TD030. I’ve read several posts of people with the same issue and apparently the fix is to create a second home and connect the new thermostat. That worked right away but it’s a weak experience. I should be able to connect 2 or more thermostats to a single home. Is there a proper fix for this yet?

Below are links to additional posts of similar issues.

Hey cffrank, 

 

Thanks for posting and sorry for the delayed response. 

 

Just to confirm, are you getting a specific message or a code on your Nest app when adding the second thermostat? If yes, what is it? Also, is it possible to connect them to another network like a mobile hotspot if available to we can cover all the bases?

 

Best,

Yes. I get code TD030.

I did not try connecting the thermostat thru a second network. I won’t be at the property again until President’s week, but I can try it then. If I connect my phone and the thermostat to a second network to add the thermostat to the same house, will I be able to connect the thermostat back to the original network and it will still be connected to the same house in the app? If it makes any difference, my network is on Google WiFi at that property.

Hi cffrank, 

 

Appreciate the prompt response. Sounds like a plan then ― let me know how it goes by then. 

 

Also to answer your question, yes, you should be able to add them back to the same network and the same home in your Nest app. If those two thermostats would successfully connect to the other network, that means that there is a certain setting on your Google Wifi network that it preventing the two devices to be on the same home together. I suggest that you check on this link for more information as well as some suggested steps.

I’m not going to be at that property for another 4 weeks so I can’t try your recommendations. You can close the thread and I’ll create a new one if I need help.

I’m getting the same error and same problem with adding a second nest to the same HOME on the app.  Every device can connect to the network WiFi.  Is it a problem that the second can’t connect or “learn” from the first installed and what do you recommend?
