Cannot Add Second Nest Thermostat to App

BRENTS — Fri, 05 Nov 2021 20:23:58 GMT

I have 3 Nest learning thermostats for my home (I have three separate units). I have added one, and it connected to WiFi just fine, and connected to the app - it's all setup and working. The second thermostat will connect to WiFi just fine, but I cannot get it to connect to the App. It gives me the m15 error. I have reset the thermostat 4 times, tried different WiFi networks, removed security, etc, to no avail. I just cannot get this second thermostat to connect to the app. I'm waiting to get this fixed before I connect my third, or I'll just have to find another brand.

If any of you have any recommendations, please let me know!

Thanks.

Any luck? I’m having the exact same issue and it is SO FRUSTRATING!

I’m having the same issue. It is frustrating.

Still nothing...I'm at a loss.

I figured out why my second thermostat wouldn’t work. It was the Wi-Fi connection. I got the thermostat to work with no Wi-Fi and not connected to my nest network ( no Wi-Fi so can’t do this regardless). I then reset the Wi-Fi network on the thermostat. It reset and then I left it searching for for my houses Wi-Fi. Nothing showed up but then I spun the dial up and down a few times and then all of a sudden the nearby Wi-Fi networks appeared and I saw mine. I picked it and then it connected. Then I checked for a software update right on the thermostat and there was one. I updated it. Then I open then nest app on my cell and added to my account, using the QR code, thus adding it to my nest network. That did it for me. It’s been working all day fine. I hope this helps others.

This is unnecessarily aggravating due to poor product development and no support. It is NOT possible to connect a properly wifi-connected thermostat to the app, without resetting it and then searching for the entry key or QR image - or both. This reset leaves the sensors "associated with a prior account." In other words, unless your thermostat is already in the app, you can not manage it, delete the sensors, etc. To add it, the "support" presumes that the entry or QR codes (to add to the app) are available on the display. Pain every step of the way. There is no way for the phone app to find a thermostat even when both are configured to the same wifi network. There is no way to reset the sensors, OR, even re-connect them to the same thermostat even with NO change in wifi network. Scanning the QR from back of the display .. app still asks for the entry key... then, asks for "symbols on the display." Forced to try again, what eventually worked was scanning the QR image from display after full reset. But now the sensors are "associated with another account" even though they were accessible prior to reset.

I had the same problem but discovered it was because of my router extenders (Orbi). When I shut the Orbi Satellite down, the Nest Thermostat was forced to jump to the same wifi device and it worked as described in the user's guide.

I have an Orbi system as well and tried your solution….worked like a charm. So simple of a fix after a couple of days of frustration. Would recommend trying the same to any others of you who have a mesh/satellite wifi system.

I had same problem. Could not add a second device to the app. It was giving me a TD030 error code. Apparently the nest app was first trying to find my first thermostat and couldn’t connect the two because the two nest devices were too far apart. Try adding a second and third “home” to the nest app. Almost like you have different geographic locations within the app. Click the + sign in upper right corner and add the device to the second and third location. Worked like a charm for us.

Having worked with Nest Thermostats for awhile as an HVAC Technician I have discovered a (aggravating) work around connecting multiple thermostats to one home. I discovered this while adding 5 Nest thermostats to a huge home in Raleigh NC. If you can add one to the app but not another, simply remove the first one from the app and then add the second one first. Then add the first one back. Had to do this several times with other technicians out in the field and haven't had any issues adding multiple Nests since discovering this work around. Hope this Helps

This worked for me also. Just got done with it, had to do a factory reset on the original unit(first one) once i Got the second unit to connect. Removed the original unit that connected successfully. Added the second unit that wouldn't connect. It's now connected properly. Added the original unit installed it wouldn't connect initially but indicated to do a factory reset of the this unit. Once I did that, the unit successfully connect now both working on the same network. Thaks you for the tip.

This solution works, thank you so much! I just bought a house and wasted three hours trying to reset all the Nest Thermostats (connected to previous owner's app). First thermostat was easy, the 2nd and 3rd just wouldn't add to the app. I tried every other solution out there (reset WWN setting, use personal hotspot), nothing worked. Until I saw this post. After deleting the first one, the 2nd and 3rd just added properly.

Shame on Nest team who can't even provide any good help besides "reset your WiFi router".

THIS! 100% solved my problem. Had no idea the Orbi satellite was conflicting with communicating with the 1st nest. Unplug your satellites and try to do the QR code method.

This solution worked for me as well! Thanks, HVAC Trainer, and everyone else who weighed in with this solution that worked, unlike the so-called “help” from Google.

Following an earlier suggestion I updated the Nest software to 6.2-22 and was able to connect multiple thermostats in the Nest App after doing that.

Thanks for this. Don’t know how or why, but this works.

What you described is my exact problem, too. As a work around, I had to create another home, called it the zone I was trying to use. Then under that home I added the second Gen 3 Nest thermostat without any issues at all. No matter what I did, it would not recognize the second thermostat under the primary home with the first Nest thermostat. This is all strange since google shows a diagram of a multi system house using two Nest thermostats. https://support.google.com/googlenest/answer/9250906?hl=en#zippy=%2Cmultiple-thermostats-in-the-same-home%2Czoned-systems-are-different-than-multistage-systems

I had to do the same thing. It is not ideal, but it is a good workaround.

Just wanted to confirm this worked for me. I do also have an Orbi, but just removed the first and it worked like a charm allowing me to add the second. Having to re-add the sensors was a pain. It it just took a little time to re-add them manually.
