A lot of off-the-shelf consumer smart home products do suffer from the drawbacks you've listed, but they do not generally apply to the smart home concept. My home is automated using components that use the KNX standard, and although the initial investment is higher than a conventional electrical installation, I'd argue maintenance is actually simpler and cheaper – as pretty much all of it is in the software.
Additionally, there's quite a few benefits:
- It's all wired, so it's been rock solid;
- It's vendor agnostic;
- It's entirely local, so there's no subscriptions or even an internet connection dependency;
- There's a ton of gateways available that allow me to interface with non-KNX products;
Overall, I'm pretty happy with it. It is just a matter of convenience however, it's hardly a must-have.
