It is supposed to read it every 5 minutes and it used to do that, but now the data looks like this: I guess the data doesn't come through every 5 minutes anymore.
I guess I'll try to reset the whole thing and see if it makes any difference.

Best regards, Michiel.

Hi Rolandet,

as you can see I also posted an issue with the Growatt script. Do you also have issues that the script doesn't read the power continuously? Are you using the latest version from github?

Best regards, Michiel.

Hi Rolandet, I'm not a php expert, but I assumed it must be somewhere in the lines of the script where the URL for the data is setup: $curl = curl_init(); $url='http://server-api.growatt.com/newPlantAPI.do?action=getUserCenterEnertyData'; curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl ...

Hi waltervl, thank you for your reply. I checked the log on Domoticz. It seems that one time it shows the total power and the next 5 minutes not. Domoticz_log.jpg As you can see the first time the first total energy is 6748000 Wh and the second time it registers 0. There is no error though. Do you ...

Hi, I am using sincze's growatt php script to read my solar panel data from the growatt server. Since a few months (I think) the power data is not continuous anymore. During the day it drops to zero, so the total energy will not integrate to the right value either. For example, today's graph looks ...

Problem solved. I took the latest script from incze's github and now it works again. Apparently, there have been some changes in the script with respect to the version I had. As far I can see the login form has changed on the 16th of June, so that's probably why I started seeing zeros since mid June ...

@petervandersman, did you ever find out why this happened? The script hasn't changed. I'm not a php expert, but there must be a way to debug the script. @PieterS, I'll take a look at this. I have no idea what you meant by all of that, I guess I can find some info about it on the internet. Best ...

Has anyone experienced this recently as well?

Best regards, Michiel.

If I return to the old script (the one from github) the growatt domoticz device is updated again, but with zero values again. Best regards, Michiel.

With the old script the login was successful (I could also see this in the log). With the adjusted script I do not receive any values.
Best regards, Michiel.

I didn't have negative values, but zero values from one day to another. Now I updated the script according to your suggestions in this thread, but now the inverter does not update in Domoticz at all. I'll attach the updated script in this post, maybe you'll the problem right away. BTW, what is the ...

Hi sincze,

the URL is: http://server-api.growatt.com/newLoginAPI.do
I didn't change the script until the zero values started to show up. I made the changes you suggested.

Best regards, Michiel.

Hi everybody, since last Tuesday my growatt inverter only displays zero values in Domoticz. Nothing has changed, so this puzzled me. I found this thread and I updated the script according to sincze's suggestions. However, now my growatt device is colored 'red' in Domoticz, so it is not updating ...
