I’m now considering setting up home assistant on a virtual machine and I’m wondering how can I get a wired connection to the same 2nd WIFI?
I thought originally you wanted a wired connection, hence the suggestion for data diode which could be plugged into LAN side of 2nd Wifi segment ?
any chance of a diagram of what you are after, especially what has access to internet and what does not (segmented)
