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.
A Symphony of Colors
Siebenuhr Mini transforms time into a visual experience with its dynamic color display. Each minute of the day is represented by its own unique hue, starting with deep blue at midnight, transitioning to red in the morning, and ending with green in the evening.
Smart Features for Modern Living
The Siebenuhr Mini comes equipped with built-in Wi-Fi and full NTP support, ensuring accurate timekeeping. It also integrates seamlessly with Home Assistant, the popular open-source home automation system. The clock has 2 buttons included on the backplate, which lets you
Brightness Control: Adjust brightness via the physical controller or Home Assistant, with settings preserved after power outages.
Toggle through the the personalities
The Siebenuhr currently support the following personalities:
Color Wheel (default): Rotates through all colors daily (midnight is blue, morning is red, evening is green).
Solid Color: Set one color to display continuously.
Random Color: Displays a new random color every minute, with a smooth 500ms crossfade.
Mosaic, Rainbow and many more.
With Home Assistant, you can also send notifications to the Siebenuhr and even read the power consumption of it.
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.

The 2025 collection
A ridiculously large, modern take on the classic 7-segment clock from the '80s oven. Looks great in the living room or the lobby of your office.
The tabletop- and shelf version of Siebenuhr. At the size of 23 x 8 cm it’s a great fit for your bookshelf or desk.
As likely seen in the lobby of a Las Vegas hotel in the 60s, hanging over the shag rug while you walk with your screwdriver-cocktail towards the penthouse-lounge.
Product pipeline
It takes us up to 7 Years to get from idea to product (insert the ‘kill the engineer and release the product’-quote here). And we have a full pipleine of products that we haven’t released yet, as some guy always comes up with something that could be improved. Or Nore just forgets to update the webshop. We need to talk to him…. .

Solid Difference ❤️ Home Assistant
Home Assistant is a popular home automation software that is very popular in the Solid Difference team. Therefore we offer full support for our products (where it makes sense) for Home Assistant. All Siebenuhr’s and other planned products have full Home Assistant support, so you can control the clock, it’s brightness and color and even send 4-letter notifications to it.
