Hi,
You can check how to do so .
If you have problem can provide raw data returned by your app ? First query should return all "yourprotocol.php" values, second _startup.php values, and third _check.php values.

username and password shall be passed via "Communication options"

[dr-ni]

The script mi600 can only supply the above mentioned three values:
webdata_now_p
webdata_today_e
webdata_total_e
It's returning all results as string.
Other neccessary values should possibly delivered as a fixed dummy.

Can you add an example protocol that is only feeded with neccessary fixed dummy values?
I've tried to modify solarlog.php but was not working only the test in the Inverter section wored.

[dr-ni]

Have now started my own dummy example:
example.php.txt
example_checks.php.txt
example_startup.php.txt

is this correct?
The power seems to jump and nothing is logged?

[jeanmarc77]

I need all data value return by your app with explanation

[dr-ni]

my app can get these solar grid-sided values (one phase):

• webdata_now_p: actual solar power (feeding to grid)
  command:
  /usr/local/bin/mi600 solariv admin myPasswd webdata_now_p
  answer string:
  421 W
• webdata_today_e: cumulative daily solar energy (daily feeded until now to grid)
  command:
  /usr/local/bin/mi600 solariv admin myPasswd webdata_today_e
  answer string:
  2.83 kWh
• webdata_total_e: cumulative total solar energy (feeded until now to grid)
  command:
  /usr/local/bin/mi600 solariv admin myPasswd webdata_total_e
  answer string:
  187 kWh

[jeanmarc77]

Your total kWh counter isn't precise enough => KWHT is the total counter (a Wh precision is needed)
So it is useless to write a protocol for that one, 123s ain't suitable unless you can have more precision

[dr-ni]

We do'nt need these counters. We can count the webdata_now_p

[jeanmarc77]

even though you'll miss some data but that's not that important.
You need to have 3 digits behind the comma (2.83x) can you do so ?

[dr-ni]

I could supply wh precision why is this precision needed?

[jeanmarc77]

Graph avg power is calculated from that

[dr-ni]

what is missing in my dummy example?

[jeanmarc77]

all cmd request ;)
Please read carefully the wiki all is explained

[dr-ni]

can I also use dummy values for that?
where do I have to add the cmd dummys?

[jeanmarc77]

example.php.txt

something like that

[dr-ni]

Ok seems to be working. I'll test it a few days and will then integrate the new counter and all the mi600 bash stuff and curl call into a mi600.php so that your 123Solar logger can fetch all data from the Bosswerk Inverter without any additional app

[jeanmarc77]

Great, keep me inform

[dr-ni]

Have now started to hack in my mi600 protocol:
https://github.com/dr-ni/123solar_mi600/blob/main/scripts/protocols/mi600-webif.php
How should I write to DEBUG and how can I throw a not connected alarm which is visible in the UI?

[jeanmarc77]

looks good.
Normal debug is 2> (stderr), that won't throw things in the UI (stdout for normal output)

[jeanmarc77]

You can also put

if ($DEBUG) {
file_put_contents("/var/www/html/dt.txt", $SDTE.": Pnow=".$Pnow." P=".$P." dt=".$DT." E=".$Etotal." Err=".$ERR."\r\n", FILE_APPEND);
}
