Marstek Venus E Batterie incompatible with modBus adapter

Open bas-eng opened this issue 8 months ago • 2 comments

Describe the bug
It seems that the modbus adapter cannot handle a gab in the address range which is the case for the Marstek venus battery with elfin WA11, see details: https://forum.iobroker.net/topic/81443/adapter-modbus-und-marstek-venus-e-batterie/7?_=1750534051694

The HA version works in my setup, see link

To Reproduce

  1. Connect Venus E and Elfin WA11
  2. Configure the adapter according to the addresses specified here: https://duravolt.nl/wp-content/uploads/Duravolt-Plug-in-Battery-Modbus.pdf

Expected behavior
Read all values from the Venus E battery

Screenshots & Logfiles
see link above

Versions:

  • Adapter version: v6.3.2
  • JS-Controller version: 7.0.6
  • Operating system: Rpi OS

Aus dem Forumsbeitrag kann ich sehen, dass wenn Gap gibt, reagiert Speicher (nicht Adapter) mit Fehlern. Das kann man umgehen indem man Read size klein macht. ioBroker kann SEHR große Ranges unterstützen, die Speicher dagegen oft nicht
