Error Starting service #5

Closed adrianrocruz closed 3 years ago

adrianrocruz commented 3 years ago

Good afternoon,

Could you help me?

When I start the service I find the following error

statring setup opening modbus opening db setting db setting params main 1 error: list index out of range main 2 error: list index out of range SELECT min("Insulation") as "Insulation" FROM "Huawei_info" WHERE time >= 1600992000000000000 and time <= 1601078400000000000 and Insulation > 0

I don't know how to solve it.

Thank you very much.

guess you are doing a new install? The system should be able to go beyond those errors, for they let you know you couldn't retrieve data from the db (the first one could also be you don't have a meter).

Does it continue running (do you see loop in the logs?), or it crashes? If it runs, it should be ok after a few days of gathering data. It needs to be up at midnight to record some of these values

Good afternoon,

I've already managed to make it work, I keep seeing those entries in the log traces.

But now I can visualize with graphs the data that is being taken from the inverter and transferred to the influx.

I am very grateful for the effort made to carry out this project.

Best regards

@MaxPomy,

Glad that it is now working for you. If you could let me know what it was, would appreciate it.

Thanks :)

Good afternoon,

Of course the problem was that I couldn't create the logger table on the influx. I understand this would be due to lack of permissions. I gave him GRANT ALL PRIVILEGES and he started to display the data. What is interesting is the possibility of entering the value of the KWH for import and the KWH for export. This way we can calculate the balance and know how much money will be sold on the invoice.

Thank you very much!
