Describe the bug A clear and concise description of what the bug is.

I try to install my Solarman DDZY422-D2 Smart Meter using the integration ha-solarman. When setting everything up, I got an error message "Échec de la configuration, nouvel essai: [SERIALNUMBER] Querying IP-ADRESS:PORT failed: [0, 0]."

Attach the debug log As a file or using the 'code' formatting.

From the setting, add an integration set your IP address Port Serial number select solarman_dtsd422-d3.yaml apply setting Wait for the confirmation and notice the error message "Échec de la configuration, nouvel essai: [SERIALNUMBER] Querying IP-ADRESS:PORT failed: [0, 0]."

I don't know if it's the right configuration path as it's the D3 on the choice list

Additional context Add any other context about the problem here.

I don't know if it's a bug report or if it's a request feature to add the configuration .yaml for the D2 smart meter (I thought D2 / D3 where the same.. ?)

Yes now it uses correct one. Unfortunately w/ the same result.. 😞

can it be the port that cause issue ? by default 8899 ? what could be wrong.. it's so frustrating at this level to not be able to integrate it even with the modbus xls 😞

Any troubleshoot I could do locally ? The errors are because the meter doesn't answer back the data we're looking for right ? Or it's the modbus that is not correct apparently ?

No, it's not the port. The smart meter is responding with an error/exception code, which means that the request is wrong (wrong address/wrong function).

The best you can do is to request the proper/full MODBUS documentation for the smart meter from IGEN. Apparently the one in the XLS file is wrong and incomplete.

hi @githubDante , how are you ? I got answer form the support team of solarman, and they confirm the file is the good one.. what can we do to integrate it ? from where the issue can come from ? :/ thanks mate and have a pleasant day

[davidrapan]

Did you mentioned what responses are we getting from the meter?

[bobybob69]
