We use our La Metric in the office with an integration for Slack (https://www.slack.com) and a handmade solution for build notifications (software development) from Visual Studio Team Services, which sends messages to the clock via Powershell.

Absolutely libidinous product, even if of course the fine-tuning of the apps (still? :-)) have limits.
For example, I would like to be able to freely define the number / duration / order of the individual visualisations, but they are not very flexible by default.
even if the product is perhaps not "very country-specific", one can get used to the remaining English and yet this device offers many more setting options than all that I was previously familiar with.
I will buy a second device, because I am fascinated by it. Although the alarm clock can be operated quite intuitively, you should take enough time to play with it... ::-))
For me, it's the coolest gadget I've ever had.
The display is very legible, large and bright during the day and automatically dimmed to perfection at night.
Although plastic for the price hammer product

I am completely satisfied since the radio alarm clock also has a snooze function. Of course, you can programme many great apps (if you can). My idea would be, for example, an alarm clock that has different alarm tones/music/sounds depending on the weather.
The apps are otherwise quite international and not necessarily Switzerland-specific, except for a few newspapers. But that can change quickly, because a few new apps have been added in the last few weeks.

Where can I switch off slumber?

Cool

Go to the homepage and look at all the apps that are available :)
It can be as simple as that.
