I bought two Nest thermostats this winter because they worked with only R-W wires. I turned off the learning feature, as it was useless for my house with its combination of passive solar and radiant heat. However, the API is/was quite simple and I was looking forward to writing my own controller. Still, I had this nagging feeling that I shouldn’t have bought them. Thanks for confirming my anxieties, Google! I can’t trust you, but I at least can trust you to be you.
