Yes, your thermostat and that control box communicate wirelessly. The 2 wires that go to it are power only.
I actually have the wires behind the thermostat. The red and white are the only ones connected. The remaining 3 are not connected at either end.
This is a lot of wires! Can you show a photo of the wires connected to your furnace board? DISCLAIMER: I’m no professional and only ever fiddled with this kind of stuff for the first time with my own system, so follow at your own risk: If you already have the 5-wire cable running up to your thermostat from the control module, I would try connecting the wires directly from the furnace to the thermostat - just match the wire colors and cap them with the wire connectors like I did at my splice (photo below). You would be bypassing your current control module as I don’t think it will be necessary any longer.
Ok, then you could use the wyze, if the green and yellow wires work. You will be disconnecting the wireless module. Do you have any other thermostats, or just the one that you are replacing with the wyze? Also, what device is connected to U1? is it a humidifier? How many wires do you have in the wall behind the thermostat?
Only one thermostat. The wires are not connected to anything on the Ac and furnace side (not the thermostat). Just hanging there
Can you show a larger image of the controller board that shows where the wires go?
Sorry, not the schematic, the actual wires. They are cropped off on the image you posted earlier, and I’d like to see which of them are bundled together, Also show the wires that are not connected to anything that go to the thermostat, on the furnace side.
The loose white wire is actually supposed to be connected to C along with the blue. Slipped out when I was taking the picture
What wire is in the same bundle as the red wire that is currently in Y?
I assume that the blue, green, yellow, and one of the red (R) wires and the white wire in W1 go back to your furnace, is that correct? And the white wire that goes with the red wire from U1 goes to a humidifier?
Where do the unconnected wires from the thermostat end up?
These are the wires that are currently not in use
As for the first part of your question, I’ll have to get back you when I get home. There is a humidifier but I never used it nor do I know if it works. Was left behind from previous owner.
Thanks!!!

If you don’t care about the humidifier, then it would be quite simple. First turn off power to the furnace. Then take the blue and white wires out of the controller from the C terminal in the middle of the board, and attach them to the blue wire that goes to the thermostat with a wire nut. Take the yellow and red wire out of the controller from the Y terminal and attach them to the yellow wire that goes to the thermostat with a wire nut. Take the Green wire out of the controller and attach it to the green wire that goes to the thermostat with a wire nut. Take the red wire from the R connector in the middle of the board and attach it to the red wire that goes to the thermostat with a wire nut. Take the white wire out of W1 and connect it to the white wire that goes to the thermostat with a wire nut. Then, at the thermostat end, connect the Red wire to Rc, the Blue wire to C, the Green wire to G, the Yellow wire to Y1, and the white wire to W1.
Setup the thermostat using the wyze app and tell it that your “previous thermostat” has the following wires: R, C, G, Y, W.
Everything should all be hooked up properly if you followed the previous instructions, so once you have double checked all the connections (post a picture here if you are not sure first), you should be ok to turn the power back on and your wyze should power up properly.
If it doesn’t power up, then there’s probably a short somewhere, or your wires are not actually connected to the thermostat - maybe a splice somewhere where they are not connected?
