- Extracted the logic for filtering implemented devices into a separate method `_getOnlyImplementedDevices`
- Created a set `allowedDevices` to store the allowed device types
- Updated the filtering logic to use the `allowedDevices` set for checking device types
- Removed unnecessary conditions for filtering devices
Fix nullability issues in `Action` model
- Added null checks for `actionExecutor`, `entityId`, `name`, `type`, and `productType` properties in the `fromJson` method of the `Action` model
- Set default values for `actionExecutor` and `entityId` if they are null
- Updated the type casting for `name`, `type`, and `productType` properties to avoid potential nullability issues
