What's behind it
A recreational vehicle must work where there is no guarantee of mobile coverage: in the mountains, on a ferry, in the middle of the desert.
OpenCamperCore is built from the ground up so that no internet connection is needed to control, monitor and automate the vehicle. Operation is via web interface, app on the local network or classic buttons.
Remote access and online services switch on as soon as there is a network again — without anything failing in between.
Real-world example
Example: You control lighting and energy via the local web interface with no signal — the operation runs on the vehicle network.
