Titel: Using Modbus to Control Battery Charging Schedule (SMA Inverter / Sunny Home Man
Beitrag von: middlejoyeux am 23 März 2026, 04:12:24
Hello everyone,

I'm looking to use the module mentioned above to control or block battery charging at specific times via Modbus on my SMA TP inverter and/or Sunny Home Manager.

I understand that something similar has already been implemented before. MadMax has kindly agreed to share his code again here, which would be greatly appreciated.

Thanks in advance for the support!

Please post this in the proper branch "Wallboxen und E-Fahrzeuge"

Looks like this belongs in the "Wallboxen und E-Fahrzeuge" section, you'll probably get more relevant answers there. Maybe repost it there and include your exact Modbus setup for better help.
