2019.1.0

Improvements in this Release:

Common

• Update all dependencies
• Improve documentation in Antora and JavaDocs
• Improve Gradle build:
  • gradlew antora to build the Antora docs inside /build/www directory. 40df39d
  • gradlew buildEdge to build an OpenEMS Edge fat-jar at /build/openems-edge.jar
  • gradlew buildBackend to build an OpenEMS Backend fat-jar at /build/openems-backend.jar
    building using gradle automatically increases the OpenEMS additional version information
• Use JSON-RPC for communication between Edge, Backend and UI. This was huge. Read 7207fc4 for more information. Some highlights:
  • Clear communication protocol between OpenEMS Edge, Backend and UI
  • Fully asynchronous handling of JSON-RPC requests allow thousands of simultaneous connections
• Apply Checkstyle on some bundles: https://checkstyle.org/eclipse-cs/#!/
• Fix bugs with old references due to dynamic OSGi. Avoid keeping static references to Channels and Components.
• A lot of overall bug fixing and improvement of code quality
• Add OpenemsNamedException to get defined IDs for OpenEMS errors

Edge

• Add Controller for High-Load timeslot (German: "Hochlastzeitfenster")
• Add Nature for PV-Inverter
• Implement Solar-Log 14b32db (read current PV production + set PV power limitation). Thanks to @abraovic
• Add PV-Inverter Fix-Power-Limit Controller. Allows setting of a max PV production power.
• LimitTotalDischargeController: make Force-Charge Power configurable
• Improve + finalize API for Modbus-TCP Slave Controller
• Use OptionsEnum for all Channels. No simple enums are allowed anymore. e866cf0
• Implement FENECON DESS Series (PRO Hybrid, PRO Compact,...) 628ac14
• Add ComponentManager. eb286cd It provides access to
  • an OpenemsComponent via its Component-ID; this reduces the need to keep static references to Components.
  • a Channel via its ChannelAddress; this reduces the need to keep static references to Channels.
• Add Modbus Bridge simulator
• Improve StateCollectorChannel
  • _sum/State collects all informations/warnings/faults from all OpenEMS Components centrally. This is a first step to a user alerting system
  • show _sum/State in DebugLog
• Implement OsgiValidateWorker: it verifies that all configured Components are actually running
• Improve REST-Api Controller: constantly write values till timeout 90785ec
• Fix FC6WriteRegisterTask e463682. Thanks @Philip1Karmann for finding that bug.
• Refactor AbstractOpenemsComponent.activate()-method. No need for properties, as they are available via ComponentContext
  • Get rid of mandatory 'service_pid' in every Component Config.
  • Make Factory-PID available
• Add EVCS simulator
• Add EVCS Controller
• Add OneFullCycleController: executes one full charge/discharge Cycle on an energy storage system
• Add generic error handling for Controllers b6e13d6
  • Introduce Controller-Channel "RunFailed" as StateChannel
  • Allow Controller.run() to throw an Exception -> sets RunFailed Channel
  • Update all Controllers accordingly

Backend

• Improve all service APIs
• Implement Backend-to-Backend Websocket server
• Create Timedata.Dummy service
• Backend.Metadata: add authentication via username + password

UI

• Refactor Chart Sections
• Refactor UI language selection
• Fix formatting of numbers using 'formatNumber'
• Avoid having 'Edge' and 'Config' as @input parameter; use Service instead
• Refactor handling of UI Widgets
• Add EVCS Widgets to Index & Historic view
• Add Download Protocol as Excel for Modbus-TCP Slave Controller

And a lot more little things...

2018.7 "Edge-OSGI Pre-Release"

This release marks the first platform alpha release for OpenEMS Edge OSGi. It contains a completely rewritten framework based on modular OSGi bundles. It is kept compatible to OpenEMS Backend and UI as far as possible. Any new developments should be based on this platform.
