This is a school project and we are working with 2 different technologies (home assistant and openhab) i am working with the HA part and my group partner with openhab and we need to visualise both parts and both need to be able to use the same data.
You can still wire HA into the network
good point didn't think further into that.
Wifi is just a wireless Ethernet (in very very basic terms)
