OpenEMS/openems: 2023.3.0

The first OpenEMS Hackathon in 2023 took place on 23rd and 24th February at the headquarter of FENECON. Apart from extremely valuable discussions and brainstormings, more than 6400 lines of code were written on these two days. Most of the Pull-Requests are still in the review phase, so please feel to leave your comments there: https://github.com/OpenEMS/openems/pulls. We summarized our results at the OpenEMS Networking Friday. See the video here: https://www.youtube.com/watch?v=xCY4bv-of8M

    • UnableToUpdatePrices: general HTTP error
    • FilterIsRequired: multiple Homes where retreived from the API and it is not possible to identify without filter (i.e. more than one valid 'Home' was parsed)
• KACO PV-Inverter: make Unit-ID configurable for Modbus/RTU (#2056) Thanks @SebastianRinger
  • Made Modbus ID configurable, since previous hardcoded modbus ID of 1 did not work for Modbus RTU.
• SunSpec compatibility:
  • AbstractSunSpecMeter: fix Energy values (#2059) Thanks @tsicking
  • AbstractSunSpecMeter: add Energy per Phase (#2060) Thanks @tsicking
• Implement the Alpitronic Hypercharger DC charging station (#2071) Thanks @hydroid7, @sebastianasen
  • The charging station comes with up to four physical connectors. This implementation is designed in a way, that each connector is represented by an individual OpenEMS Component. So if you have a Alpitronic with two connectors, please configure two "EVCS Alpitronic Hypercharger" with the connector configuration property set to SLOT_0 and SLOT_1 respectively.
  • Supported Firmware versions: 1.7.2 and higher.
• Virtual Meters:
  • VirtualMeterAdd: bugfix for ActiveConsumptionEnergy and Min-/MaxActivePower (#2058) Thanks @tsicking

• ESS Fix Active Power: handle Hybrid-ESS (BREAKING CHANGE) (#2092)
  • Add a configuration setting hybridEssMode, that allows defining the DC-side power set-point
