When I compare your old thermostat picture with the Wyze thermostat pic, I see on the old one that there’s a cable connected to the W2 terminal. That cable is marked with the W1 sticker and plugged into the W1 terminal on the Wyze thermostat. Is that how the Wyze App told you to mark that cable? With W1 instead of W2? Looking at the setup video, W and W1 are the same selection when you set up the Wyze thermostat, but W2 is separate from that selection. Or if you have a heat pump, you might have had to select AUX instead of W/W1, which the App would have told you to yet another terminal on the Wyze thermostat.
As far as I understand, W1 is stage 1 heat and W2 is stage 2 heat, so it may be that, instead of the usual stage 2 heat that the old thermostat provided, you are now getting stage 1 heat instead?
From what I can tell, the cable marked W1 on the Wyze thermostat may not be in the correct location. I would double check that by resetting the thermostat and re-configure it using the proper cable designation (either W2 or AUX)
Disclaimer: I am not an A/C tech, I am just telling you about a difference I see in markings between the old thermostat and the new one
