Issues decoding SPH5000 messages #439

Open patcher-ms opened 9 months ago

patcher-ms commented 9 months ago

Hello, I have a SPH5000 hybrid inverter and I am having issues with decoding its messages. With the default I was having reading entirely off. I set ginvtype=sph and that partially helped me to get more realistic results. I haven't checked them all though.

I noticed that the parsed timestamp has definitely some issues. It is way off from the actual time and, more concerning, I am getting the same timestamp for different messages, which in turn causes very little data to be available in InfluxDB (even if I take account that the timestamp is wrong).

Example log entry:

Other values (e.g. totworktime) are different so it looks like there is an issue decoding the timestamp.

I'm happy to investigate this further myself but I'd appreciate an hint on where to look

patcher-ms commented 9 months ago

Looking closer into this and matching with the code, 170a07131006 should be parsed as 2023-10-07T19:16:06. Any idea why multiple messages sent by the datalogger could have the same timestamp?

patcher-ms commented 9 months ago

Using the timezone from the server (via the env variable gtime="server") allows me to see all the measurements in InfluxDB. I'll later go through all of them to double check that the mapping is correct for my inverter.

johanmeijer commented 9 months ago

The only reason I can think of is that either the datalogger is re-sending the same data (but then the data should be also the same) or the datalogger can not keep its time (some dataloggers has problems with that). Then gtime="server" is indeed a solution.

What type of datalogger do you have? Have you tried to update the firmware of the datalogger?

patcher-ms commented 8 months ago

I have a ShineWIFI-S, running firmware 3.0.0.2 which as far as I understand is the latest. Using gtime="server" is an acceptable solution.

I also have a question. I see that I am getting two different kind of messages:

- Grott automatic protocol detection
- Grott data record length 585
- layout   :  T060136XSPH
- no matching record layout found, try generic
- Record layout used :  T060136XSPH

and

- Grott automatic protocol detection
- Grott data record length 839
- layout   :  T060104XSPH
- no matching record layout found, try generic
- Record layout used :  T06NNNNXSPH

The second message seems to work as intended. For the first message I also get a - Grott data ack record or data record not defined no processing done in the logs. Is that expected? The payload seems to contain some data but I yet have to decode it.

I had the same issue, see #442 . I've solved my issue also by using the server date time instead of the one sent by the data logger. I'm still not sure if the issue was caused by the datalogger or that it was because of an interpretation issue, I didn't had the motivation to investigate that.,

I also saw this in the logs after I change invtype parameter value to min.

     - Grott data ack record or data record not defined no processing done
alsocalledchris commented 8 months ago

I'm also having issues with the same SPH inverter - for me the 'pvenergytoday' is not correct - it is currently showing 6.4 in Grott's log and then that is translated to 64 in the sent MQTT message - the Shine App is showing 12..1 (I have 2 strings). (running Docker image 2.8.2)

I do not think that is a problem. Grott logs show a formated value of the pvenergytoday (specified in the layout definition). The MQTT messages (and Influxdb) contains the unformatted values as beeing sent by the inverter. The entry today is being sent in 0.1 Kwh units. This 64 * 0.1 watt is 6.4 Kwh

@patcher-ms

The second message seems to work as intended. For the first message I also get a - Grott data ack record or data record not defined no processing done in the logs. Is that expected? The payload seems to contain some data but I yet have to decode it.

That is correct the first record (the "03" data type) is a announcement record which is not decoded (and does not need to be decoded) by Grott.

In one of the next releases I will change the message so it will be more clear.

Thanks for your reply. You are correct that the MQTT was correct for the given value of 64 to 6.4 however my point was that it should have been 12.1Kwh or I guess 121 - the value is not correct from the template (sorry for not being clearer). Is there a way to debug this?
