You can give it commands via google home to use radio or spotify songs as an alarm tone. No need for a phone.

No, this function does not work for me.

I don't think it works except maybe via Google Assistant (never managed it). You can't connect your mobile but Spotify works. When you set an alarm, there are a handful of ringtones available.

Hello, I would like to answer this question. But as I ordered it as a gift I wasn't able to test it. I wish you a good day.
