Hello,
I want to connect my Marstek Venus 5 kWh home battery to Home Assistant. Does anybody know what kind of RS485 module I need for that?
First make research what integrations / components are available if any. That gives you direction which approach to use, TCP or RTU. Then you can decide hardware to use.
I use GitHub - tomquist/hame-relay: Bridge MQTT messages between Marstek storage systems (Saturn/B2500, Venus, Jupiter) and local home automation, enabling simultaneous use of the official mobile app and local automation control. and that works fine with Jupiter C

Hello rvb55555,
I use a LilyGo T-CAN485 board and program it with Esp-home Device Builder
You can follow in my link the easiest way to get it to work …
PS And of course the great work of Superduper1969 too
