@bpaauwe Good question. You CAN run your weather station without any internet connection or cellular connection. Here’s how it works…
Internet connection (or mobile cellular connection) is required only for initial setup to create app username/password and to configure your weather station. You can then physically locate your station anywhere and the HUB will broadcast data via BLE directly to the app, and via UDP.
You just need to make sure that you do not ‘log out’ of the app – as username / password is required to communicate with your HUB for security reasons. If for some reason your app logs out, you will need an internet connection to log back in – so that our servers can authenticate — again, for security reasons.
PS - the indicator light on the back of your HUB will glow red when there is no Wifi. It will glow blue when actively connected via BLE.
