It would be fun stuff to build, but I feel like you'd struggle to make money. Google and Amazon can afford to give away the hardware, and they can smuggle their ecosystem into your house as a thermostat or a smart speaker or a phone app, or whatever.
Like, how do you persuade the audience of enthusiasts (think: Unifi buyers) to pay for a subscription to managed software they run on their own computers, raspis, whatever? I would probably spend $10/mo on something like that, but much above that and you'd be fighting against the armchair commentary of users who won't appreciate the effort that goes into stability and will basically have a "no wireless, less space than a Nomad, lame" attitude.
