App will not accept my existing ID and password. Now, with abrupt update, I am completely in the dark. I use this app to control the thermostats in my beach house.6 hrs away. I was never told this was going to happen. Spoke to customer service multiple times during setup navies of their ‘server issues’. If you have these in a vacation home, get ready to travel!!! Btw, mine are two weeks old. Old account information does not transfer.

You have to be physically in front of your thermostats to add them to the new app. Goodbye to the was not fun! BUYER BEWARE!! I have received a refund from my contractor and now have NESTs. I need to be physically at the thermostat and ADD THEM AGAIN!!! He said if the power goes out, same procedure. Called CS and was told they only try once to reconnect after 15 mins. While here, Spectrum internet went down for a couple hrs.it happens. UPDATE 2 - Finally got them reconnected after a 6hr drive one way. My wife says it has to be bad for me to write a negative review which may be my first. And yes,I have uninstalled and reinstalled the app as veral times. On Monday I walked through and reset all 5 thermostats and got them back online and back on the app, only to have all 5 showing the “X” within two days. Whether it’s the app or the actual thermostats, we are not happy. We are left at this point with only one conclusion. We pay for unbelievably fast and reliable service. Our internet provider also came and examined our internet supplies and found no issues on our part. Specialist have examined and ran test on all our equipment and zones and found no issues. After speaking with one of the reps, he insisted it had something to do with our wireless/internet hardware or software. We have many other wireless tech devices in our building that hardly ever get knocked off line. It’s very frustrating and quite time consuming. I have lost count of how many times our app shows an “X” by the status of the units WiFi connection, which requires us having to walk through all the steps as though we were setting up the units online for the first time. The purpose of buying the wireless thermostats was to turn AC’s on in our building 45-60 minutes prior to opening.
