T8-G3 Modbus

[Fuchs]

Hi guys,
I have a new T8-G3 and want to connect it to my home assistant via modbus.
The T8-G3 is connected to my home assistant via an isolated USB-RS485 converter.
https://www.waveshare.com/usb-to-rs485-422.htm

I downloaded the https://github.com/nathanmarlor/foxess_modbus integration.
When installing, I chose "USB to RS485 Adapter".
The adapter selected is "Waveshare USB to RS485 (B)".

Home assistant finds the adapter, but unfortunately doesn't get a response from the T8-G3.
I naturally tried swapping A-B of the RS485 first.


1. Question
Is the T8-G3 supported at all?
It is not listed in the documentation


2. Question
Does anyone know the pinning of the T8-G3 connector?
The documentation shows an 8-pin connector, but I found a 16-pin connector (a meter from the installer is connected to pins 3+4).

I used pins 1+2


3. Question
Can the ID247 fit?
The inverter does not have a menu item where I can read this.

Thanks and best regards from Germany,
Marc

Sorry to say that the https://github.com/nathanmarlor/foxess_modbus integration doesn’t work with T series inverters, some work has been done in this integration https://github.com/assembly12/Foxess-T ... -Assistant

You can also get on-line via the cloud fairly quickly using this integration which use the OpenAPI to get data (albeit based on the 5 minute samples the datalogger sends) https://github.com/macxq/foxess-ha
