Thx, for your comments. I’ve placed my question on the right thread. I first did not know how.

Hi @Kaoh , I have three Marstek batteries connected to Homey Pro via Marstek Energy Storage app: B1: VenusE 2.0, firmware v158.1 (via Battery Connector app for now) B2: VenusE 3.0, firmware v149, connected via LAN B3: VenusE 3.0-uusin, firmware v149, connected via LAN Commands work fine …

The modbus registers arn’t document so, checking is a problem. I don’t own a v3 myself so playing with the storm of bad test results on the internet I can not do. In theory every converter should work as long as they do pure modbus tcp not any wrapper so like http or json or mqtt etc

Hi, OK, I understand. I will try with the one I have. First waiting for the new plug to V2 I have lost… Best regards, Marko
