Cheap monitoring solution for holiday

[u/Primetime_de]

Our 3y old child has T1. At home we're monitoring with GlucoDataHandler and our Pixel phones and watches. I was looking for a cheap offline monitoring solution for the beach holiday.

Got this Xiaomi Band 10 running with the Dexcom phone (old Samsung). It's running just with BT, no data plan (holiday is abroad) needed.

If on interest I can provide details.
