Plugwise 2.0

[bouwew]

I've started to think, how can we further improve our code?

My first thought was, start from the top: what does HA require as input data?

Device data to pass to HA:

• connections: mac address(es)
• (configuration_url: should be the gateway address as there are two config/setup-options)
• hw_version
• identifier: appliance_id
• name
• name_by_user
• manufacturer
• model
• model_id
• (serial_number: not available)
• suggested_area: location name
• sw_version: firmware version
• (via_device: is the gateway)

Now we use dev_class only for finding Master_Thermostats, and for migration.
The migration-function is old, could be removed in the future.
Should we get rid of the dev_class? Maybe not because it tells us what the device-type is.
Maybe rename to device_type?

So, the dict to return should be:
{identifier: {device_type: ..., hw_version: ..., name: ..., name_by_user: ..., manufacturer: ..., model: ..., model_id: ..., suggested_area:... , sw_version:..., etc.}

What to so with the binary_sensors, sensors and switch dicts?

• Keep and extent: add button, climate, number and select dicts? Would allow us to get rid of using device_class/_type.
• Or remove them? We could prefix the various names with the platform-name?

Also, which data is fixed, which data requires refreshing?

• name_by_user, suggested_area, sw_version might be updated, others are fixed unless there is a hardware update (new cv-ketel/warmtepomp), or e.g. a Lisa is replaced by a new one.

For instance, when changing the function of a Plug and renaming it to that new function, the backend picks that up but HA doesn't. Also a reload does not fix this if I remember it correctly. Maybe because we don't use the "name_by_user" attribute?
From looking at the HA code, it doesn't: "name_by_user" is the first pick, otherwise "name" is used for device-naming.

So, for us, using name and model are sufficient: name = Lisa badkamer, model = Lisa --> don't use "name_by_user".

So, the dict to return then becomes:
{identifier: {device_type: ..., hw_version: ..., name: ..., manufacturer: ..., model: ..., model_id: ..., suggested_area:... , sw_version:..., etc.}

We should detect a database reset --> how to handle? Remove and readd the integration? Or detect and force a reload?

@CoMPaTech have a read and feedback please.
