Hi! I'm trying to see if my current system is compatible with Google Nest Thermostat. I ran through the setup guide in the Google home app and it says it's not compatible because it's missing a "W" or "Y" wire. I just wanted to confirm this is the case. It's strange to me though, because the system was installed only a year ago, before I purchased this home. If it really isn't compatible, what can be done to make it compatible?
I don't see a way to upload an image of the current wiring directly, so here's an imgur link showing the current wiring: https://imgur.com/a/RzW9J8N
Thanks!
