How to extend my Twinkly Matrix both physically and virtually
This article refers to Twinkly Matrix devices
To physically join several Twinkly Matrixes together to create an even bigger light show, just hook the lightweight bars together at both ends of the curtain:
Moreover, if you like the idea of extending your display and creating an even larger setup, why not use the App's grouping feature, creating a virtual group between two or more Twinkly Matrixes or between Matrix and other Twinkly devices with an RGB or RGB+W LED profile to illuminate areas with multiple light sets that are seamlessly linked together.
To group several Twinkly Matrix devices with each other, or Matrix with Curtain, Icicle, you can create Join, Sync and Area groups, while to group Matrix with all other Twinkly devices you can only create groups in Sync or Area mode.
Here you will find all the information about the Grouping function.
Can I stack my Matrix panels vertically?
Twinkly Matrix panels are designed to be installed side by side. The supplied mounting clips are specifically intended to attach the panels to the aluminum support bars, ensuring the Matrix is properly tensioned and maintains its intended appearance.
A horizontal (stacked) installation is not officially supported, as the LED branches may naturally bend downward due to gravity. This can affect both the visual appearance of the installation and the intended LED layout.
That said, there is no technical restriction preventing you from creating a vertical arrangement if you are able to securely tension and support the Matrix. With a suitable mounting solution, multiple Matrix panels can be positioned one above another to create a taller display.
Please note, however, that when stacking Matrix panels vertically, the gap between two adjacent devices will be larger than the standard spacing between individual LEDs. This difference should be taken into account during the design phase, especially if a perfectly uniform pixel pitch is important for your installation.
