Question about Amazon Echo Dot (4th gen.)

We cannot guarantee that it will work with the Huawei device as there is no Amazon Alexa app in the official Huawei AppGallery.

There is a tutorial on the Huawei website where it says that the Alexa app can be added from the HiLink app but it refers to one of the Huawei devices and not Amazon Dot: https://consumer.huawei.com/ph...

NOTE: You can download the Amazon Alexa application by following the on-screen instructions in the HiLink application for technical support and related services.

To configure the product, the customer must have the Amazon Alexa app on their phone or they can do so via a browser: How to configure an Amazon Echo Point: https://support.park.edu/support...

No, unfortunately the Android and IOS app is not available in Switzerland, you have to configure it from an Amazon account.
