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.
-

2021.8.0
Highlights
- Downgrade apache.felix.scr to 2.1.20 (#1438)

Add JSON-RPC Requests: add timeout parameter (#1412)
- This non-standard extension of the JSON-RPC protocol adds a "timeout" parameter in seconds. This is the maximum time that we wait for a JSON-RPC Response. Timeout is defined as an
Optional:- timeout > 0: use the given timeout in seconds
- timeout <= 0: apply no timeout, i.e. wait forever
- no timeout: use default timeout of 60 seconds

2021.4.0
Highlights
- Implementation of Advanced Battery Protection algorithms (#1376)
- 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 (#1327)
- This new Predictor architecture uses modular
Predictors, e.g. implementation of thePredictor24Hours. These Predictors can announce for which channels they allow a prediction and provide aPrediction24Hoursresult. - 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 thePredictor::get24HoursPrediction()method or via aget24HoursPredictionJSON-RPC request to the_predictorManagercomponent. - developed within the EMSIG project: https://openems.github.io/openems.io/openems/latest/randd.html#_emsig
- This new Predictor architecture uses modular

2021.3.0
2021.2.0
Highlights
- Add Zenodo Digital Object Identifier (DOI) for scientific referencing
If you use OpenEMS in your scientific research, please use our Zenodo Digital Object Identifier (DOI) as reference: - UI: Add Delayed Sell To Grid Widgets (#1369)
- Lots of improvements on Batteries, Battery-Inverters and Generic-ESS (see below for details)
Bug Fixes and Other Changes
- UI: Historiy Consumption Fix 7e9a9e1: show correct energy values for other consumption
- Fix controller behaviour in case of unavailable values (#1365)
- This commit replaces
orElse()method calls withgetOrError().
In case of unavailable (UNDEFINED) values, e.g. because an external meter is not available, this causes the Controller to throw an Exception instead of assuming the value is zero.
An exception in a Controller sets theRunFailedFault-channel.
Specifically for control of energy storage systems: if no set-point is given, charge/dischare with zero Watt is set as default.
Set ActiveConsumptionEnergy of the EVCS. (#1362)
- This commit replaces
- Set ActiveConsumptionEnergy of the EVCS.
- Adapted unit tests due to changes on the Dummy classes.
Changed the energy channel acconrding to @StefanFeilmeier 's comments.
Set the KEBA hardware maximimum current depending on the dip-switch settings and no longer on the "curr hw" value. - Adjust missing corrections.
Set State to Not ready for charging if there is no propper connection to the EV and EVCS.
- Adapted unit tests due to changes on the Dummy classes.
- UI: History Bug Fixes + General Fixes (#1369)
- history label time unit adjusts automatically
- show alias for fixactivepower live widget + disable browser translate

- ESS KACO 50: update handling of battery data (#1378)
- Fix SunSpec: rounding issues with ScaleFactors (#1380)
- The SunSpec protocol definition uses integer registers with separate scalefactor-definitions in separate registers. Due to the way OpenEMS is setting a register from a Write-Channel, the value was rounded to integer before the scalefactor was applied.
- This pull request fixes the behaviour by using FloatWriteChannels instead of IntegerWriteChannels for SunSpec registers with scalefactor.
- Battery-Inverter KACO: improve watchdog handling c9e9e08
- increase watchdog timeout to 60 seconds
- trigger the watchdog every 10 seconds
