Supporting re-Configuration
In previous releases it was not possible to change a config_entry. When you wanted to change settings like the IP, toggle WS or other initial settings you had to do this via the additional configuration. This approach implied, that the core configuration values existed twice - once as config_entry.data and then a second one as config_entry.options.
Few days ago I realized, that HA is supporting also a 'reconfiguration' of an existing config_entry - overwriting/updating previous data.
