Release 2021.5.0

New Implementations: KMTronic 4-Port Relay Board & GoodWe Battery-Inverter for Generic-ESS

Update of Local Timeseries database „RRD4j „

Now there are more options to adjust the number of files written to the hard disk and the files are generally smaller. Auto-update for old files is provided.

Many OpenEMS Backend improvements (backports from FEMS)

  • Controller.Backend.Api: sends data on each Cycle, asynchronously
  • Backend Edge-Websocket and Ui-Websocket services: performance improvements
  • InfluxDB Backpressure: handles cases when we write too much data to the InfluxDB
  • Add timeout for JSON-RPC Requests

Release 2021.4.0

Implementation of Advanced Battery Protection algorithms

The „Battery-Protection“ implementation serves as an addition to low-level battery management systems (BMS). It allows a fine grained definition of battery protection parameters and handles logics that are shared between different BMS implementations.

Implementation of a new Prediction architecture

  • This new Predictor architecture uses modular Predictors, e.g. implementation of the Predictor24Hours. These Predictors can announce for which channels they allow a prediction and provide a Prediction24Hours result.
  • The entire process of getting a prediction is handled by the PredictorManager. It knows which actual Predictors to ask for their prediction, post-processes these predictions and returns them either directly in code via the Predictor::get24HoursPrediction() method or via a get24HoursPrediction JSON-RPC request to the _predictorManager component.
