Siebenuhr Mini: A Compact Timepiece for Your Home or Office
The Siebenuhr Mini is the perfect smaller sibling to the original Siebenuhr. Its compact design fits seamlessly on tables, bookshelves, or any space where style meets functionality.
This innovative clock reimagines the seven-segment display with uniquely shaped digits, blending the roles of a clock, lamp, and art piece into one striking object. Manufactured by hand in Switzerland, the Siebenuhr Mini brings a touch of elegance and craftsmanship to any home or office.
The new Siebenuhr Mini comes with an automatic brightness-sensor. This way, the Siebenuhr adjusts its brightness to the room-ambiente automatically and get’s bright during daytime and dim during the night.
The Siebenuhr Mini comes directly with a USB-C Port and a white cable. The Power supply can be bought seperatly, but you can also use an existing USB-C power supply.

Siebenuhr is now fully Open source
We rewrote the Siebenuhr firmware and open sourced it. Those who are interested in extending the source, we recommend to do it with the ESP Home edition of the Siebenuhr source, where you are able to connect every Siebenuhr fully with Home Assistant. As the buttons are fully programmable, you can build your own stop-watch, make the Siebenuhr display much more stuff, reprogram the whole functionality or just develop your own personaliaties for the Siebenuhr.
