SmartTag 2 and Home Assistant: a possible marriage!

The 2025.3 release of Home Assistant revolutionized SmartThings integration, raising hopes for total compatibility across all devices. Unfortunately, Samsung’s SmartTag 2 seemed to be the exception, despite being promising hardware – I had already envisioned them as the ideal companion for my bicycle!

The problem? The tag is visible in HA, but essentially unusable. These little Bluetooth gems, equipped with a button and a tiny speaker, had enormous potential, especially the button function to control my garage door when I return home by bike. After various searches and a bit of “tinkering,” I finally managed to find the solution to make them work properly!
