GridBOSS RS485 modbus documentation

[diso12]

Does anybody know if (and where) can I obtain the GridBOSS comm protocol documentation? I am trying to control my system using RS485 instead of wifi dongle.

One of the manuals says to get it from the distributor, you can start there. Have you come up with a solution yet? I'd be curious to do it like this as well

I’ve been asking EG4 for it for a month or two, “They are working on it” is what I’ve gotten back.

We currently do not have the Modbus available for the Gridboss.

Can you please clarify, you don't have documentation, or are you saying there's no modbus support at all?

All: after some reverse engineering, there is limited GridBOSS support for home assistant via MQTT: https://github.com/galets/eg4-modbus-monitor

I just did solar assistant to get the inverter data into home assistant.
