If you’ve ever experienced May 17th (Syttende Mai) in Norway, you know it’s not just a national holiday—it’s a full-day celebration filled with parades, flags, traditional clothing, music, and an impressive amount of ice cream and hot dogs.

Unlike many other countries, Norway celebrates its Constitution Day with children’s parades (“barnetog”), marching bands, and a strong focus on community and joy rather than military displays. It’s loud, colorful, and full of energy from early morning until late evening.

So what if your smart home could join the celebration?

In this post, I’ll walk you through 10 creative Home Assistant automations that will elevate your 17th of May—whether you want atmosphere, fun for the kids, or just a smoother day.
