Summary
The predicted datapoint write endpoint allows users with only read:assets privileges to write predicted datapoints.
The endpoint:
PUT /api/{realm}/asset/predicted/{assetId}/{attributeName}
accepts write requests from users lacking write:assets.
The implementation appears to check READ_ASSETS while performing a write operation through:
assetPredictedDatapointService.updateValues(...)
