I installed openhabian correctly on the raspberry. I configured it with wifi and it works well in my house. But if I take the raspberry and take it to work and connect it to eth0 ( no wifi) I can not contact him, I do not see dhcp requests
I didn’t know it was a male raspberry pi!!
This is a networking issue rather than an openHAB issue even if you have openHABian
Have you searched google?
