Amazing furnace by the way, 
We install hundreds of those, can’t get a better furnace.
The best option is to have a new 18/8 thermostat wire ran to give you the extra wires you need.
You can use the C Wire Adapter and connect it to W1. The thermostat will still trigger W2 when there is a call for 2nd Stage Heat. Your G to the thermostat will become the C wire, so that would go in the C spot. Just verify your wiring in the Wyze App to make sure it detects R, C, G, Y, W1, and W2.
