I am frequently away from home (whether on family vacation, a business trip, or out around town), but I have a number of important resources on my home network—as any homelabber does.
There are services I like to access remotely like my NAS with my giant media library, my edit server with all my active projects, and especially Home Assistant, which lets me monitor all aspects of my home.
Some people rely on individual cloud services from IoT vendors and have a bunch of apps to connect to each type of device independently. As someone who has dealt with numerous security breaches for numerous services, I know not to trust 50 different cloud-connected devices in my home.
That's why I'm a 'self-hosted' homelabber, and why I try to find devices that don't leave my local network.
