WYZE Thermostat with no C Wire. RC, Y, G & G1 only

Home

Hello,

I have an AC only system with RC, Y, G and G1 wires only. I have already checked, and these are the only terminals on the control board. Currently only the RC, Y and G are hooked up and there are additional wires available.

Would it be possible to hook a 24v adapter to these additional wires to power the thermostat and how would I hook the wires up on the thermostat?

Thanks!
