I’m not sure how to wire this since I discovered that in two instances one wire is used for two terminals (red for r and rc & yellow for w and y).
Can someone please advise if this setup is compatible and how this configuration translates to the wyze thermostat?
@speadie might know. Here’s a thread to peruse where he’s been active recently:
Looking for help wiring in my new thermostat to an old hvac unit with no circuit board.
I’ve got 4 wires at my current thermostat:
G, Y, W, R and 2 unused wires wrapped around the bundle Blue and Brown. I found these wires feeding to the unit, as pictured. How do I connect the adapter? If you need more pictures let me know. Thanks.

Apologies if you’re already familiar with these techniques. Others who happen along may not be and it generally helps enrich the board.
It’s a heat pump with a non-heat pump thermostat/wiring harness.
Tell the wyze app you have the following wires:
Y : Yellow
You will need to install the C adapter, if you have issues, take a picture of the furnace side of the wires and I can walk you through it with a custom diagram.
