Smart home automation isn't for everyone. Many relatives see it as that weird hobby I have and don't see much of the value. (And I agree given the time I spend tinkering.) Even I would likely rip out most of the inherited smart home stuff in order to replace it or at least flash opensource firmware on it. Another important point I learned is that everything should work as a dumb home when the wifi, gateways, HomeAssisant or some sensors are down.
