SUN800G3 - Connection problem

[fr3ts0n]

I tried to use this binding for a Deye SUN800G3 inverter

Unfortunately it refuses to connect / show data

openhab console log shows following:

Is there something I may need to change/configure?

Thank you

@fr3ts0n - Parsing the request/response I get:

Request was from: 0x0003 to 0x0080 for logger with ID: 2305057437
Response was from logger with ID: 3945226983

So it seems you got the wrong logger ID.

Are you sure you're not using the inverter ID instead of the logger ID?

[catalinsanda]

Come to think about it, it makes sense to put a warning in the logs when this happens. It will probably help others troubleshoot the issue.

Thank you very much. With the correct ID configured it works like a charm. :+1: It's amazing how things work if you configure it correctly ...

Yes, I agree. A warning/error message could save some of your support time.
