Hi, thanks for this project!

I receive only NAK response... which setting for "-M"?

Regards, Elia

[jblance]

What command are you running? Please supply the output after adding '-D' to the command (this provides a lot of debug messages) Also can you run the 'QPI' command and let me know the result

[eliafino]

This is debug for QPI: log.txt

And this working good: inv.py.txt

[jblance]

Are you saying your working good gives a good response? (As there is not crc in the command you send) what response do you get? What do you get if you send QPI instead of QPIGS?

[eliafino]

QPIGS response is ['217.4', '101543', '49.9', '0006.6', '220.6', '01500', '49.9', '006.7', '027', '411.1', '411.1', '054.2', '---.-', '078', '00000', '00000', '-----', '000.0', '000.0', '---.-', '032.0', 'D---100201']

QPI response is ['PI16']

[eliafino]

I found info on the PI15 / PI16 protocol here and here

[jblance]

Ok, so a new protocol. The master node base doesnt deal with alternative protocols very well, but I have started a branch to specifically deal with different protocols (branch is called refactor)

Next week I'll try adding pi16 protocol handler Do you know how to checkout a branch and use that code? What do you need that the linked tool doesnt provide?

Cheers

[eliafino]

I see branch refactor, ok. The links I sent are part of a software that manages UPS, I reported it only to understand the protocol. I haven't found anything else.

No problem to send directly command QPIGS to serial or USB port. I can query QBSDV but I can't set "BSDV44.5 46.5"

+QBSDV+:: Query device for battery-discharging limits

+BSDVa b+:: Set cut-off battery-discharging voltage:

• when grid is unavailable to +a+ (3 digit decimal number, +NN.N+) Volt
• when grid is available to +b+ (3 digit decimal number, +NN.N+) Volt

I can't send over 8 characters

UPDATE: Ok I send first 8 characters and after send another characters: First send "BSDV44.5" and after " 46.5"

[jblance]

I have added the first cut at PI16 (QPIGS and QPI only so far) Can you try it against your inverter to see if it gives the correct response

[jblance]

Can you post the full debug response (add -D) to the command

[eliafino]

debug.txt

update

[jblance]

Weird it seems null padded at the start and there IS a crc on the return. Can you also do a debug of QPI command so I can see what that gives

[eliafino]

debugQPIGS.txt debugQPI.txt

[jblance]

OK they both have crc, I wonder if all responses do. Maybe set commands responses have no crc? No nulls at the start of these 2 responses though.... I'll update to remove the crc of the responses tomorrow and try to add some more commands

[eliafino]

Ok, thank you very much!

[jblance]

made some changes - so hopefully the response is correctly parsed now also added QPIBI command can you try with version 0.6.2

[jblance]

also let me know which commands you need the most (start with queries)

[eliafino]

Perfect my friend!

[eliafino]

If you can, I need QMOD and QED

[jblance]

Great, also next will be testing the output modules What are you going to do with the data?

[eliafino]

Internet page, MySQL and grafana

[jblance]

how do you plan to get it to those places? mqtt? direct? QMOD added

[eliafino]

Directly to my MySQL server. Thanks for QMOD

[jblance]

Did QMOD give a reasonable response? added attempt at QED...

[jblance]

so i have the idea of output modules. if you have python code for the mysql updates, it is possible that an output module could be created (probably with a config file somewhere for the specific details etc) then the command becomes mpp-solar -p /dev/hidraw0 -P PI16 -c QED19900101 -o mysql or similar

[eliafino]

Interesting... but for now QED -> "NAK", no way to have production for today: QED20200721

Not finished jet, here

[jblance]

try QED now not sure 'checksum' is the same as the CRC though, do you have an example that works from your python script?

[eliafino]

I was unable to obtain the reading with any script, not even sending the command directly to the serial port. Only "NAK"

[jblance]

can you try QED with version 0.6.4

[jblance]

and post a debug log if it fails again

[jblance]

oh, missed padding the checksum, fixed in 0.6.5

[eliafino]

Now I see "0000000", in the next days I can connect solar panels and try to read production.Thanks very much for now!

[jblance]

Great
