Hello,
the Galaxy SmartTag2 is only compatible with Galaxy Smartphones & Tablets with Android 9.0 or higher
Best regards from Schwalbach,
Your Samsung Service Team

Thanks anyway for the quick answers

However, a Google Pixel Smart Tag is also already in the works

So I don't have a Google mobile. However, I have registered the tag via the smartthingapp. But I can't give you a 100% yes.

No, only with Samsung.
