Growatt Webserver Plug in stopped working

[Cees2439867]

Hello All, Just the last two days I am struggling getting the readout of my Growall inverter working again as it shows on the following picture:

Anyone have an idea or maybe a solution?

[bmjvannunen]

I am experiencing the same error since around 8:00 (GMT+2) on Tuesday August 15. The plugin exits with: Error: Growatt: Growatt returned a status: 405

It seems Growatt has changed the api (login) again.

[sincze]

Mmm indeed 15-08-2023 07:55 indeed. Needs investigation guys.

• Needs new weblogin. If APP exists I can have a look at the APP as well.
• Needs new Data url: https://server-api.growatt.com/panel/getDevicesByPlantList

I see similar results for Omnik and Solis Inverters.

• Needs new Data url: https://globalhome.solarmanpv.com/plant/infos/data
• https://globalhome.solarmanpv.com/maintain-s/operating/station/search?order.direction=DESC&order.property=id&page=1&size=20

Fine if the updates are minimized so accounts will not be locked anymore.

Lock outs?? Mmm never experienced that with pass2php those run exactly every 5 minutes.

This is the Plug in!

I got that, hence I use Pass2PhP ;-) , both came from the same guy that has limited amount of time ;-) and both are experiencing the same issue. First up on the list is fix Pass2PHP

I am also having the same issue, but is there an php for Growatt to fetch the data? Where can i find the source?

[jan-vandenberg]

I also had this problem, see here: https://www.domoticz.com/forum/viewtopic.php?p=299171#p299171

[sincze]

Looked at the APP and did not want to work with me using a proxy in between. So felt a bit lazy today.

Solves the issue if you are able to run node-red.

[Cees2439867]

Just found out I am writing on the wrong software package, I use growatt-inverter.php. Hoping a lot you will update it? Would be much obliged. Thanks for helping us.

[sincze]

For the moment I have the data flowing in via Node-Red. Now I can have a look at their login mechanism as that was changed.

[HarryVerjans]

The Growatt Plugin at my brother is not working 100% but much better than my own implementation. I installed his version on 18 december 2022. I do not know if the 1061,8 Watt over a longer period is actual correct data.

[sincze]

The problem is that recently they disabled the old entrypoints for data collection. Now even the app seems more secure ;-) than before.

[HarryVerjans]

My own current implementation is accessing too frequently de Api server, that causes a lock out of the web account. As this happens access via Shine Phone is also blocked. Access via webbrowser is in this case no problem. Is there a possibility to limit the access of the plugin to less connections. Is the runagain parameter an option to do this.?

published on github so i can have a look?

[HarryVerjans]

At this moment my own implementation of the plugin, that is updated yesterday from github, is running oké. My brothers is stuck, I better did nog mention it was running better. I changed the parameter runagain from 6 to 18 if this is the solution I do not know. In the morning the plugin is struggling in starting up. I wil look in the morning how it is running and report here.

[oepi-loepi]

I am developer of a Growatt plugin for the toon thermostat (rooted). This also did stop working some days ago.

Odd thing is that the plugin still works in my qml debugger (Windows) without any problem. Only when i put it in Postman, a curl request or an xml request from a linux device it does give the 405 error.

[oepi-loepi]

Deze werkt dus wel in mijn qml debugger maar niet meer op de toon sinds een paar dagen.

[oepi-loepi]

GOT IT WORKING ! I now changed my scripts for toon and is working: First check server server-api.growatt.com. If this gives a 405 error try again but now server.growatt.com

https://github.com/ToonSoftwareCollective/solarpanel-plugins/blob/main/GROW1.plugin.txt

[HarryVerjans]

At this moment I am getting data every 5 minutes. But as I look at the graphs online and in Domoticz they do not match. Access looks oké but the data from the API is not so accurate. Entrypoint 08:00 08:05 and 08:10 are having the same power value. But for the moment I am happy that there is a working data connection. But changing parameter runagain from 6 to 18 is not the solution, I guess.

[Cees2439867]

Yes, just changed three instances of server-api.growatt.com to server.growatt.com in the file growatt-inverter.php and yes it works again: The values are terrible now. I will change that in the database tomorrow. So Happy! Thanks to you all, certainly "oepi-loepi" and Sandor of course.

[sincze]

Haha Cees, no PR ;-) Let me change to server-api.growatt.com to server.growatt.com

13:35 Updated the Pass2PHP file, changes needed on 3 locations.

[sincze]

Updated the plugin to 1.0.3 according to the Pass2PHP urls provided by "oepi-loepi" and @Cees2439867

[tonbor]

And less updates so no more locks?

[oepi-loepi]

@sincze maybe do the double check since they might change server again in future.

[tonbor]

after git pull and rename growatt server, not working the latest was working in the evening, not working anymore......

[HarryVerjans]

What about the runAgain at line 227 should this also be changed in to 227? AND The // in line 84 results in a syntax error # should be used for comments in python ;-)

Crap mixed up python and php.

[tonbor]

[sincze]

back to version 1.0.2

relax 1 typo and no errors as mentioned by @HarryVerjans Now have to wait and see what happens tomorrow. Maybe the response changed as well but at least the login is working again.

[tonbor]

no it is not

[sincze]

Remove your Growatt icons, that is what the error is all about!

[tonbor]

Ok, I did, indeed the plug in is working BUT still a locked Growatt account because of to often access by the plug in.

mmmm that is interesting... you clocked the five minutes ??? it should trigger every five minutes. else the 'run again' statement need to be modified twice with higher values.

[oepi-loepi]

I have the same if i run multiple instances. E.g 2 toons, domoticz and the app. If i only run 1 instance i do not have this problem.

[tonbor]

Would be fine if the update interval could be chosen by the user himself

[oepi-loepi]

Not for my toon app since the database runs at 5 minute interval

[oepi-loepi]

And you can choose allready in the domoticz plugin if you change the interval in your cron action? So why you need such option?

[sincze]

WIth the php file it indeed it is easy to do it in cron (*/5) the others use the plugin. But PR's are more than welcome.

[tonbor]

php is not a plugin
