Miaomiao2 with watch - is there an alarm?

Just got a Miaomiao 2 and it seems to be working great, although I’m on the first day. (Thanks to all who gave me advice on it.) My phone is ancient and has poor battery life, so I was thinking of getting a WearOS watch to connect to it via Tomato. I had a couple of qs....

  1. From searching I can see that the watches will vibrate on hypos (etc.); can you also make the watch make a sound?
  2. Does the watch need to be connected to a phone, or will it work as a standalone?
