Initial review done.

I note from the documentation that ADS also supports other platforms such as light, switch, binary sensor, cover etc and that they usually require configuration in YAML, how will these be configured for users using ConfigFlow, is there an auto-discovery mechanism available?

In the scope of this PR, only the Hub can be set up by the ConfigFlow. The possibility remains to add it through the configuration.yaml, alongside the other platforms.

I am working on the possibility to set up the lights, switches etc... through the config flow, in separate PRs.

Alternatively, there may be a way to auto discover devices, but i have to do a bit of testing. :)

Ok, so in the meantime the user would be expected to set the hub up in ConfigFlow and then any extra devices in YAML? That seems a little odd unless there is a use case by which a user would want to only have a hub configured?

Or is the plan to have all of these PRs merged in the same release cycle?

Yes, it is a bit odd, but this PR is already pretty large, so i don't want to include all the other work in here. Also the possibility to set up the hub by YAML remains.

Yes, the plan is to mark each PR such as "Needs to be merged together with #...PR "

In that case, please mark this as draft whilst work is ongoing. And think ahead about merge conflicts and so on.
