When you change a setting for a tado° product using Amazon Alexa, it is treated as if it was a manual input on the tado° device. This means that your tado° switches to Manual Control.
Note that Amazon Alexa works via a cloud-to-cloud connection. Therefore you always need a working internet connection to communicate with your tado° devices over Alexa.
