COnnecting with thermometer away from home

Is there a pond thermometer that I can buy that once connected to my home wifi can be used away from home ( when out of the country )
I have garden cameras that allow me to do this when connected to wifi abroad so do you do the same.
If yes…then which model do I buy
Thank you

Maybe you can see if IBS-M2 + IBS-P02R meets the needs.
The IBS-P02R-O pool thermometer connects to the IBS-M2 via radio frequency.
IBS-M2 connects to phone ‘INKBIRD’ APP via 2.4GHz wifi.
Once connected, the phone can view data remotely using different networks.
