As from time to time people ask whether there are openHAB shirts for sale, I’d just briefly like to mention that we have ordered a first batch of polo shirts (after having had a few samples first to see that they are of excellent quality!), which we will bring to the Smart Home Day in Ludwigsburg and sell them for 20 EUR each (we do not make any money on them).
We will likely do this on other future occasions as well, but if you still wonder what to do on Oct 21, this might be another good reason to join us in Ludwigsburg!
