3.0: Ultimate Edition

3.0: Ultimate Edition

Statt jeden Wert einzeln liest der Baustein soweit möglich ganze Blöcke vom WR ein. Diese Register werden intern gesammelt und dann verarbeitet. Damit sind die Werte mehr akkurat und es konnten viele zusätzliche Werte hinzugefügt werden.

Es ändern sich aber fast alle Ausgänge.

Getestet mit dem Kostal Plenticore 10 Plus. Sollte weiterhin mit PIKO IQ und PIKO CI ebenso funktionieren.

Bugfix release

This version official supports the PIKO CI inverter

Issues fixed:

• Loop in scale factors crashes homeserver when the scale factor is >1. This happens for all PIKO CI inverters.
• Inverter state register between PIKO CI and PLENTICORE differs. Implemented workaround
• Added pyserial dependency to avoid runtime issues when using pymodbus (that has not occurred on the homeserver yet)
• Small documentation improvements

Before filling an issue please ensure you're using the latest inverter firmware!

v2.1

Bugfix release

• InverterPower (AC/DC conversion rate) register is only a 16bit register.
