By default, we offer 3 tagging libraries: an Apple SDK, an Android SDK and a Javascript library (which also supports Angular 2, AngularJS and ReactJS).
The technical feasibility of tagging a connected car or fridge application (IoT) will depend on the technology it relies on.
If none of our 3 libraries can adapt to your tagging project, you also have the possibility to manually build your own queries through the Craft your hit method (Analytics Suite 2) or via the Collection API (Piano Analytics). This type of tagging is highly recommended for more complex projects where our standard libraries cannot be adapted properly.
