Solved! Go to Solution.
Go into the apps settings and make sure that you have ticked the box "automatically connect me to my homehub when in range"
@adly the settings you need to adjust are on your iPhone and not the app.
@gg30340 I'm not sure where to find any such setting. There's no such thing in the BT WiFi app or in iPhone settings.
I use the BTWifi app on Android and the setting is there.
I don't know if it is the same on the iPhone but if it is, you open the app and click on the three dots at the top right. Scroll down to settings and it should be there.
@gg30340 unfortunately there's no such option with the iPhone. Due to the way the iPhone works the app just installs a connection profile that makes the phone autoconnect to the BT WiFi hotspots. The app can't manage any WiFi settings and the iPhone WiFi settings are very limited.
It turns out there is a way to prioritise networks with the iPhone to avoid this issue without having to disable auto-connection for BT Wifi hotspots. Basically, with the iPhone, the more you manually select a network the more it will be prioritised. Thus, if you select your home network a few times, it will be selected before the BT Wifi networks.
