I moved into a house with 2 Nest thermostats, one for downstairs and one for upstairs. I downloaded the app and paired both of them with my phone. My downstairs unit was no longer showing up on my Nest app. However, it still is working, i.e. I can control my A/C and heating temps using the thermostat. I have tried to pair the downstairs unit with my phone using the QR code and the entry key without success. The error message I get say "Something went wrong. The App is having trouble connecting to the assisting Nest product. Make sure that you are close to it, that it's online and that your phone is connected to the same Wi-Fi network. TD016(4060).
