GROTT compatibility with old inverters

[p0macs]

Hi!

I have a very old inverter. When I look on the Growatt server (where I'm logging the data with the data logger since 10 years), I can see this information:

Mode: A0B0D0T0PFU1M3SC Version: GBAA3200 Build Number: G.1.8 Device Model: Growatt 3000

Started using Grott in proxy mode, it forwards the data records to the Growatt server just fine, but almost no records can be decoded, except one coming from the Growatt server. All the others are not decoded because of "Data less then minimum record length, data not processed"

I have the "default" inverter type. Any chance to have my inverter data decoded?

Thanks for your help.

Additional info: Now I have changed the inverter type from "default" to "min", but nothing really changed. Still the only packet which can be decoded, is the T000103MIN, but this is not processed as well.

All the others still have less data than the minimal record length. Is the any way to see the data on the log anyway? (like above)

[p0macs]

Trying to change the minimum record length...

But then:

Why it is not recognized as number?

[p0macs]

Analyzed the records, and it looks like:

• after the connection the data logger is sending one "T000103" record - the #announce record
• then it is sending every 5 minute a "T000104" record - a #data record

Now, this is not processed because the protocol detector has only definitions for the "T02NNNN" or "T05NNNN" or "T06NNNN" protocols. Anybody has an ide how to decode the "T000104" records? I have tried to fake it as "T02NNNN", but the field values are not good.

[p0macs]

Hi! You can close this issue. I found the t000104.yaml in the Examples folder :) After copying onto the main folder the records are processed well. Thank you!

[p0macs]

Works with a little configuration.
