Nest thermostat won't connect to app

Bob3 — Fri, 29 Oct 2021 00:52:52 GMT

My 3rd generation Nest Learning Thermostat won't connect to the app. Everything else is good, including Wi-Fi. I tried both the QR code and the entry key. The QR code tries to connect then goes to an error. The entry key hangs and does nothing.

Sorry is this a new issue (as in it used to connect but suddenly stopped working) or is this a new install or setup that you are trying to complete? It may simply be the app install on your phone, in which case I would suggest deleting the app, rebooting your phone, then reinstalling the app, this will help to clear any potentially "gummed up" settings that could be stopping the process.

I have the same issue.

Tried the app on an iPhone an iPad and and Android phone. Only 1 out of my 4 nest 3rd generation learning thermostats connects to the app. Note this is a brand new setup.

I have rebooted the phones, reinstalled the app, factory reset the nests, changed the WiFi name, turned on and off the 2.4Ghz WiFi band, nothing seems to fix it.

I get the TD030 error consistently.

Any suggestions?

Thanks!

Just pulling this from Google support here :

The TD030 error can occur because:

The assisting device your thermostat uses to communicate within a thread network is powered off.

Your phone and the assisting device are on two different Wi-Fi networks.

To check that the assisting device is working correctly, follow the troubleshooting steps below.

Make sure that the assisting device is powered on. If it isn’t, charge it or connect it to a working power source.

If the assisting device isn’t in use, remove it from the Nest app.

If you have more than one Wi-Fi network, you may have to move your phone to the same network the assisting device uses.

So... My first inclination is to do a reboot of your router , go into you Google home app and be sure that there are no "offline " devices, and be sure you only have one wireless network (no ap isolation mode or band steering features active). If this fails , then I will escalate this for you as it would be above my head!

Hey ilbound,

Did you have any luck solving the problem with your thermostats? I had the exact same issue. Bought 3 stats, first installed with no issue, connected to wifi and the Nest app.....following 2 devices gave me the same TD030 error. Tried everything you tried. Hope you found a solution and can share,

Thanks

I FOUND THE ANSWER after speaking with nest app support.

You CAN NOT do the install on a 5GH network. Temporarily connect your thermostat to you 2.4 GH network set it up then you can change your phone/app back to the 5GH network.

I have an ORBI set-up which I do not believe has a means to disable the 5GH network. Anyone have a work around for this?

You should be able to disable it by Advanced > Advanced Setup > Options will be there to enable/disable 2.4 and 5

Had the same problem and after 2 days on attempts figured out what my issue was - First thermostat set up with app fine, 2nd and 3rd would’t connect.

Problem was due to my prior setup in the Nest app, I didn’t allow Nest to connect with other devices and use bluetooth (these are not necessary when the first thermostat is setup but are needed for additional devices) so I deleted my Nest app, reinstalled the app accepting all Nest requested options, reset the thermostats (press the thermostat for 10 seconds to reset) then reconnected using the Nest app in the thermostat, and voila, both #2 and #3 thermostats connected to the app..

Hope it helps.

I had the same issue. 2 out of the 3 connected and one didn’t. I removed all of the thermostats from the nest app first, then started over by connecting the app to the troubled thermostat first. Then I added the other two after with no issues. Hope this helps!

Mikechamp — Sat, 20 Nov 2021 03:17:04 GMT

I did not need to reset anything by the way. Just delete all your thermostats from the nest app, then reconnect to them all. I started with the bad thermostat first.

I need it escalated as nothing seems to work after trying everything suggested above multiple times.

I'm having this same issue. Two new Nest thermostats in a new setup. The thermostats ARE connected to the network but wont connect to the app. I've tried connecting with two iPhones and an iPad with both the Nest app and the Google home app. Very frustrating!

Ok So I tried everything in this thread. One thing worked for sure is removing all thermostats, resetting them and starting with the one that didn't work. Also, I switched to 2.4 GHz network and they all connected.

This definitely helped me. I went through countless attempted solutions only for this one to work. I went into the Google Home app, removed the working thermostat device from my account. Tried to set up the second thermostat that was giving me issues and this time it finally got past the step of connecting to another Nest device to assist with connecting to Wi-fi. After the second problematic thermostat finally finished setting up successfully, I went back to the first thermostat and re-added it via the Google Home app and now both are working fine.

I was having a similar issue with a 3rd generation learning thermostat when installing a second one in a new location (different address miles away). I followed all the steps in the app but could not connect. I kept getting the TD030 error. Then when watching the attempted connection process in the app I noticed the animation was suggesting communication to my first thermostat. The error said it could not connect to the assisting device. The solution was that I needed to create a second home in the app, which I just didn't realize was part of the hierarchy. After doing that, the new thermostat was quick to add within the new home.

Thanks Kev1. I will try that.

For now I had to use separate google accounts and switch between them to access one or the other Nest thermostat
