growatt script does not work anymore

[ariankoster]

Since some days no values get in any more

[sincze]

Unfortunately Growatt changed their login mechanism. So needs work to fix.

In meantime I easily migrated to Node-Red and now I have even more devices to chose from.

[Cees2439867]

Unfortunately it is broken again as the data this morning show: Wrote an email to Dutch branch of Growatt how to get data from their servers...... Have little hope but one can try!

I can confirm it is indeed broken again :-(

[sincze]

The Node-Red version is still working.

Any error messages in from the script??

I notice 3 login attempts.

1. POST https://oss.growatt.com/login / Host: oss.growatt.com userName=xx&password=&lang=en&loginTime=2023-08-22+10%3A49%3A58&noRecord=true&type=1&passwordCrc=xx

{"result":0,"msg":"Username needs to be at least 8 digits long"}

2. POST https://oss.growatt.com/login / Host: oss.growatt.com userName=xx&password=&lang=en&loginTime=2023-08-22+10%3A49%3A58&type=1&passwordCrc=xx

{"result":0,"msg":"Username needs to be at least 8 digits long"}

3. POST https://server.growatt.com/login Host: server.growatt.com account=xx&password=&validateCode=&isReadPact=0&passwordCrc=xx

{"result":1}

Using the script we see an HTTP Response of 403. (Not Authorized)

[Achterhoeker]

the plugin on https://github.com/sincze/Domoticz-Growatt-Webserver-Plugin/ is working again, the php script isn't.

[sincze]

that is interesting indeed

[sincze]

Will need some minor config changes. I need to add a additional function to extract the plantID and use that to request for the data.

define('HEADER',array('Content-Type: application/x-www-form-urlencoded;charset=UTF-8',
                      'Connection: keep-alive',
                      'Host: server.growatt.com',
                      'User-Agent: Domoticz/1.0'));

[sincze]

the plugin on https://github.com/sincze/Domoticz-Growatt-Webserver-Plugin/ is working again, the php script isn't.

can you try with the current version ???

@sincze It works again:

But first it didn't then i compared with the plugin. There i saw i was using http. In the script i changed the https calls into http and that did the job. Thanks for changing the script so it works again. :-)

[Cees2439867]

With me it does not work yet. Yesterday I used the new growatt-inverter.php updated username/password, Idx and domotics url. Then executed the file with the following result:

Then, at night time I added a piece of code not to update if the counter is not above zero: lg('Growatt Inverter: '. $nowpower.' for domoticz: '.$str); IF ($todaypower > 0) { ud(DOMOTICZDEVICE,0,$str,'GrowattInverter: Generation updated'); } I have this because I used to have many times that the counter retrieved was zero. After fixing the database with the correct values for yesterday I kept up the hopes for this morning but no luck. I do not get data from Growatt.

Maybe you have a hint?

[sincze]

Put the variable in the script debug to true and share the results shown in the domoticz.log. With the supplied info there is nothing we can do as we don't see what it is doing.

Just now I took the file growatt-converter.php and carefully looked if I made any mistake. Searching the file for "debug" gave no hit. The output of the read out from Growatt shows the following: 2023-08-23 13:15:02.525 Status: --->> Cookie File: /home/pi/domoticz/scripts/pass2php/growatt.cookie exists! 2023-08-23 13:15:02.526 Status: --->> Cookie File: /home/pi/domoticz/scripts/pass2php/growatt.cookie is writable! 2023-08-23 13:15:02.616 Status: --->> Growatt Inverter: 0 for domoticz: 0;0

What else can I look at?

[Achterhoeker]

@Cees2439867 For me only http is working, still no https from the growatt servers with data. So in the growatt-inverter.php i've changed all https calls in http.

[Cees2439867]

It is not working unfortunately. Thanks for your work to help me (and others). I will enter the data manually for a while. Just bought a KWh meter from Home Wizard ([Wi-Fi kWh meter 1-fase) which promise a API. Hope this works.

[sincze]

Homewizard stuff works great. Is simple URL parsing to get it into Domoticz. There is already a Domoticz plugin (p1. Water, plug) hopefully for the Meter as well.

I am a newbee so do not kill me if I talk nonsense... I changed my password , from 6 to 8 positions. I changed line 116 in:

$url='https://server.growatt.com/newPlantAPI.do?action=getUserCenterEnertyData';
Now growatt-inverter.php works.....

I can not explain why.... Enjoy..

[sincze]

Well the hint could as well been in the clue of Growatt themselves.

{"result":0,"msg":"Username needs to be at least 8 digits long"}

But then again ;-) who knows.

This indeed shows how it should be indeed.

I updated the file, but I get only 0.0 values:

Hi Sandor, You where so right about HomeWizard! Now I have a constant flow of data in house without interfering with the data from the supplier. Thanks for your work during the past three years. Regards, Cees.

Now it works again, thanks! What did you change?

[sincze]

Github allows you to track the changes between versions Have a look ;-)

[ntpckr]

Where is the data stored of the data of the Growatt readings? I want to alter the comparing usage, because it is not correct.

[sincze]

I would say it is stored in Domoticz DB ;-)

[ntpckr]

Yes, it is, but I cannot find the exact line or table. I know where the day values are stored. So I wonder where the years are stored. Or is it calculated when I load the page?

[sincze]

Ok great. Stop domoticz before changing something in the DB.

Check for a column named calendar_meter or meter_calendar. Just go through the values and look for the idx of your device.

[Marinus48]

Since today the script works fine… I do not know why…but enjoy!
