My whole smart home runs on self written software - but only the components that are highly customized, for example the dashboard, the video doorbell (which consists of multiple devices) and presence detection. Everything that can be solved by general purpose software, I don't bother to create my own software for (like your energy consumption report example, grafana does this better then I could ever do). Using mqtt and node-red, it's easy to connect my own software to the 3rd party stuff.
