I installed openHABian on my Raspberry Pi 4 and connected it through Ethernet to my home network. Afterwards I tried to connect the Pi via Wifi by changing the openhabian.conf. But unfortunately, it changed nothing. According to the Topic: Setup Wifi after first boot by Fox27, I also reinstalled everything. But my problem now is, that I have no clue how a access the openhabian.conf. If I go to the SD directory, I see only a folder named overlays and a lot of other files. Non of them is the config file. Also it doesn’t looks in general like a OS system. Windows is also only seeing an 250 MB big SD card. So I have to access to perhaps the real directories. What can I do, which tool could I use?
Thanks in advance!
