This is an essential feature for IoT deployments as one needs to be able to:

  • detect which device is causing the anomaly
  • create distinct anomaly classes for different SKUs (e.g. 300A is OK for a 500A rated sensor but anomalous for a 200A rated sensor).

We have already implemented this feature in ES 7.9+. Please try it out.
