  • Add global .gitignore patterns

  • UI: improve detection of isOnline
  • Set default port 8085 in edge-dev.ts
  • TypeUtils: fix conversion from Double to Float
    • This fixes a bug where a double "0.0" could not be converted to float, with following error: "Cannot convert. Double [0.0] is not fitting in Float range."
    • Also applied Checkstyle on TypeUtils.

  • Introduce OpenemsOEM class which simplifies creating custom distributions of OpenEMS
  • Soltaro Battery Improvement

  • Allow SymmetricEss in EvcsClusterPeakshaving
    • EvcsClusterPeakshaving was not able to start with a SymmetricEss like Fenecon Dess. (No Reference for component ess0 ...)
  • UI register: Remove zip validator
    • Austria has only 4 digits; other countries... who knows?!
  • PQ Plus UMD96 Meter Implementation
  • Remove Predictive Delay Charge Controller
    • It was replaced by the more advanced "ESS Grid Optimized Charge" Controller (io.openems.edge.controller.ess.gridoptimizedcharge).
  • Hardy Barth Salia: implementation improvements
    • Small things like heartbeat were changed in the hardy barth software especially for the newer salia cpµ pro 2 (single charger).
    • Another problem was the external meter that is used internally in the hardy barth to provide the current charge values.
    • This meter also measures the standby consumption of the salia itself and is disabled by default - The function to enable it automatically is on hold for now, as we need a proper update process first.
  • GoodWe: add missing Write-Registers
