Support for PIKO 7.0 version 5.41 / question or new feature request?

[seebaernd]

I am new at github so be patient if i made something wrong.

I tried to use your adapter for my approx. 5 years old KOSTAL PIKO 7.0 This did not work, i think my PIKO 7.0 is not compatible with your adapter. But perhaps it is just my problem.

As far as i guess my PIKO 7.0 only has a built-in webserver to get information as a html-page, see attached screendump. Do you see a chance, to get my old PIKO 7.0 could work with your adapter? Or are there hints to get the existing adapter work with my PIKO?

As i am no programmer, i only build a small php-script that is frequently called from crontab to set some values of my PIKO 7.0 in iobroker. This is working for me as good workaround.

!/usr/bin/php

//<?php $url = "http://pvserver:passwort@192.168.1.34"; // Hier die Webseite vom Websever eintragen pvserver = user $io_set_G = "http://server2:8087/set/0_userdata.0.Datenpunkte-iobroker.Kostal-Pico-WR.Energie-Gesamt?value="; $io_set_T = "http://server2:8087/set/0_userdata.0.Datenpunkte-iobroker.Kostal-Pico-WR.Energie-Tag?value="; $io_set_A = "http://server2:8087/set/0_userdata.0.Datenpunkte-iobroker.Kostal-Pico-WR.AC-aktuell?value="; $io_set_end = "&ack=true";

$Ausgabe = file_get_contents("$url", "r");

//AC-Leistung_Aktuell

$pos1 = strpos($Ausgabe,"aktuell")+20; $pos1 = strpos($Ausgabe,">",$pos1) + 1; $pos2 = strpos($Ausgabe,"",$pos1); $data = substr($Ausgabe,$pos1,$pos2-$pos1); $AC_P_aktuell = (float) $data;

//Energie_Gesamtertrag

$pos1 = strpos($Ausgabe,"Gesamtenergie")+20; $pos1 = strpos($Ausgabe,">",$pos1) + 1; $pos2 = strpos($Ausgabe,"",$pos1); $data = substr($Ausgabe,$pos1,$pos2-$pos1); $AC_P_gesamt = (float) $data;

//Energie_Tagesertrag_Aktuell

$pos1 = strpos($Ausgabe,"Tagesenergie")+20; $pos1 = strpos($Ausgabe,">",$pos1) + 1; $pos2 = strpos($Ausgabe,"",$pos1); $data = substr($Ausgabe,$pos1,$pos2-$pos1); $AC_P_tag = (float) $data;

//Setze Werte in iobroker über die REST-API

$Ausgabe = file_get_contents("$io_set_G" . $AC_P_gesamt . $io_set_end , "r"); $Ausgabe = file_get_contents("$io_set_T" . $AC_P_tag . $io_set_end , "r"); $Ausgabe = file_get_contents("$io_set_A" . $AC_P_aktuell . $io_set_end , "r");

exit; ?>

My question is: will i have to use my own php-wokraround in the future or is there a chance to use your adapter with my PIKO 7.0?

Thanx for being patient with me. Bernd

I would guess that you put something like "http://192.168.1.34/" as IP adress in the config.... YES? -> please try again with only "192.168.1.34"

Please try "http://pvserver:test@192.168.1.34/api/dxs.json?dxsEntries=16780544&dxsEntries=16779267&dxsEntries=16777984" in your favorite webbrowser... !! pvserver has to be your username; test your password for the inverter...

please send your browser result.... should be like: "{"dxsEntries":[{"dxsId":16780544,"value":"PIKO 6.0 BA"},{"dxsId":16779267,"value":"06.41"},{"dxsId":16777984,"value":"Piko"}],"session":{"sessionId":0,"roleId":0},"status":{"code":0}}"

Hi Bernd, hard to tell without direct access to your system, but as far as I understood you'll need an Kostal UI => 6.11. There is an update to Version 6.41 for your inverter on the Kostal Homepage. Perhaps also an FW Update could be usefull. https://www.kostal-solar-electric.com/de-de/download/archiv/#Solar-Wechselrichter/PIKO%204.2%20-%208.5/Deutschland/Update/

FYI - according to sentry there are minimum 4 other user with Piko 7.0 using the adapter.... ;)

[seebaernd]

Thanx for your effort to help me. Looks that my inverter would need an update to work with your adapter.

But I am not sure, whether I will make these updates - never touch a running system. I dont have any experience with updates an my PIKO. Also I dont have a service passwort for the inverter and i am not sure, whether everything will work fine after the update. And my php-script and workaround with rest-api of iobroker ist pretty working.

Thanx again for your friendly help.

You're welcome!
