Temperature bar is absent from the iOS app. Is the AIR module not working?
It doesn’t look like you have the AIR device added to your station - only the SKY device is attached. The SKY measures wind, rain and UV/solar radiation. The AIR measures temp, pressure, and humidity.
Add the AIR unit in the app, go to Settings > Stations > choose the existing station > top right (+) add device > follow the procedure.
