Support for multiple entities of the same type on a device.
Support for Grid Connect double outlet smart switch using this functionality.
This release contains changes to the configuration and unique IDs of entities. It includes a migration that should make the changes seamlessly, but there is a possibility that your devices may go missing in the upgrade. If this happens, please file a bug with any messages from the log (or check if a bug has been filed and add any information that your log has that is not already reported).
Disable any affected entities from the Integration Options, and go to the Configuration/Entities and remove the missing entities. Restart HA and reenable the entities. Following this process, the entities may get renamed, so they will either need to be manually renamed back to the old name, or any automations or lovelace references to them will need updating.
