Just pay a pro too much to install it if you really want one
September 2, 2018
I have the C wire issue, even though the install process said it would work without it. Not awesome, Nest, that is seriously false advertising.
I received a thermostat that had already been unboxed and used. The long install screws were covered in drywall dust from being installed already, and one of the small screws was missing, as were the stickers to label the wires. More on that next.
Anyway, the battery was completely drained and the thermostat took hours to charge also.
As I followed the app to install, the part came to take a picture of the current wiring, so I did that. Then I put my phone down and finished disassembling the old thermostat. When I picked up my phone, the app had signed out and lost the picture because I had to re-start the whole process. Not cool, Nest. Fortunately I was able to recover the photo by browsing the app cache on my phone, which is far too technical for most users. Overall, my experience has been very poor. I'm waiting for a C wire adapter to be delivered tomorrow to get the system working again. I'll continue to use the system, but my initial rating is terrible because of how much I paid for false advertising and already been used equipment for full price.
