Bug Fixes and Other Changes

• Refactor Ess-Cluster (#1590)
  • Refactor implementation, use ChannelManager for immediate updates to channel values, calculate weighted SoC and add JUnit tests
• Go-e Charger: Fix minimum and maximum hardware power calculation (#1582), Fixes #1580
• RevolutionPi improvements (#1562) Thanks @clehne
  • improved debugLog() format, added some debug write channels and improved event process handling (read on BEFORE_PROCESS_IMAGE, write on EXECUTE_WRITE)
  • also: Simulator BatteryDummy - added missing StartStoppable channels
• Backend implementation for installation assistent (#1589) Thanks @mlang97
  • See also #1588 for UI development efforts for an OpenEMS installation assistant by @raphael-piller
• Improve handling of OSGi References and target filters (#1603). Thanks @sebastianasen for your valuable inputs
  • Try to restart Components if they are unavailable
    • Due to a race condition on startup, sometimes Components are unavailable to the ComponentManager. The related error message is [Core.ComponentManager(1)] : Could not get service from ref. We are fixing this by restarting (i.e. 'reconfiguring') the Component in such a case.
  • Increase ComponentManager 'ConfigNotActivated' level to 'FAULT'
  • On UpdateComponent via ComponentManager: reset target properties
    • Before if a Component was referencing 'modbus0' and you would update it to 'modbus1', there were two possible behaviours. (1) if 'modbus0' was still existing, the update would work and the target filter would be set properly. (2) otherwise the target filter could not be set, because the Component would not reactivate. This would leave the Component in an error state. We are fixing this by always resetting the target properties.
  • Set non-empty default target filter by default
    • If the target filter is made available via 'Config.java' and the configuration property is left as an empty string, the error Invalid syntax in target property for dependency arises on activate, which showed to also cause wrong behaviour later. We fix this by setting a default target filter of (enabled=true) - which is always true, but avoids the error
• Backports from FEMS (#1583)

2021.11.0

Highlights

• Implement Controller.Ess.GridOptimizedCharge 03ba135 988688a
  • Combination of the PredictiveDelayCharge and the SellToGridPowerLimit controllers:
  • Delays the charging of the AC or DC storage system based on predicted production and consumption given by the PredictorManager.
  • Even during the delayed charging, the battery is able to force charge when the sell-to-grid power exceeds the configured "Sell-To-Grid maximum power limit".
  • This is mainly used when only 70 percent of the maximum production is allowed to feed in to the grid.

Bug Fixes and Other Changes

• JsonUtils: improve parsing of Strings as booleans d2ba7b0
• UI: Flatwidget for consumption (#1472)
• SoC estimation improvement in simulator. (#1487)
  • Improved the Soc calculation by using the double value instead of float and estimating the soc through current energy value in the battery.
• Upgrade to GitHub-native Dependabot (#1462)
• Fix parsing of empty string properties to Integer 2629601
• Simulator: remove obsolete min/maxActivePower config 39e76a1

• Merge Hybrid-Generic-ESS with Symmetric-Generic-ESS (#1519)
  • This simplifies configuration in scenarios where you do not need to care if there is a DC-PV system connected to a Hybrid inverter or not. Example: GoodWe ET (hybrid) can be used without a DC-PV system.
• Bump org.apache.felix.http.jetty from 4.1.6 to 4.1.10 in /cnf (#1517)

2021.9.0

Highlights

• Implement MQTT (#1395)

  • This adds support for the MQTT protocol in OpenEMS Edge. The new "Controller.Api.MQTT" publishes data to an MQTT broker.
  • It uses the following MQTT topics:
    • edge/{OpenEMS-Edge-ID}/channel/{Component-ID}/{Channel-ID}
      • Data of Channels is published on change and at least every 5 minutes to these topics.
      • Example: edge/edge0/channel/_sum/GridActivePower
    • edge/{OpenEMS-Edge-ID}/channel/lastUpdate
      • Timestamp of the latest data update on any of the Channel topics above.
      • Example: edge/edge0/channel/lastUpdate
    • edge/{OpenEMS-Edge-ID}/edgeConfig
      • Configuration of the OpenEMS Edge instance is published to this topic as a JsonObject.
      • Example: edge/edge0/edgeConfig
  • The implementation is built on version 5 of the MQTT protocol and was tested with Eclipse Mosquitto (https://mosquitto.org).
  • Be aware that this implementation only marks the start of MQTT support in OpenEMS. Therefor implementation details might change with future versions.

• Improved Login and Session-Handling (#1013)

  • New User-Area in UI
