I’m using z-wave stuff but similar setup. Home Assistant does reach out to the cloud for some things like weather forecast and Google calendar but otherwise it will operate 100% without internet if needed. I also have cameras that while they aren’t air-gappend they are blocked from Internet access and can only talk to the NVR.
