While both options are equally good, we would advise that you install your Thermo in Wi-Fi if you can. This option gives you the most flexibility because of the Bluetooth fallback we've implemented for Wi-Fi configuration: if your Wi-Fi network is unavailable for any reason, your Thermo will be able to communicate with the app in Bluetooth.
Configuring your Thermo in Wi-Fi has other advantages:
- Your measurements are sent to the app even if your phone isn't next to you.
- Updates are done automatically when they become available.
