Problem solved the hard way, installed a shelly em3 and deleted the growatt plugin. I know this is no solution to the plugin but it works for me enjoy the weekend

I have to change the server address
in both Growatt Shinelink and Domoticz I'm using now server.growatt.com instead server-api.growatt.com
Maybe that will fix

Is it possible you needed to use your emailadress instead of a username, and now it's username? (maybe that's what I got wrong, cause i've deleted and reinstalled, and now it works)

I did a little bit of debugging and the problem is that the Growatt plugin gets the following response:
Code: Select all
{"back":{"msg":"507","success":false}}
The result is that the plugin does nothing!
But the problem is not the plugin. The problem is the Growatt API.
Because this is the exact same response that I get when I curl the API:
Code: Select all
sudo curl -X POST -H "Content-Type': 'application/x-www-form-urlencoded; charset=utf-8" -d 'password=MYMD5PASSWORD&userName=MYNAME' http:// server-api . growatt . com / newTwoLoginAPI . do; echo
So either Growatt is ratelimiting? Or something else? Either way '507' is not a very descriptive API error.
If anyone knows what this means, I am happy to listen.

507 = insufficient storage on server side.

FWIW at EXACTLY 00:00 the plugin started receiving data again.
So I *think* the Growatt API does some kind of ratelimiting and resets this every day.

See for example discussion here:

Seems 5 min polling is a good rate for keeping you unlocked.

At this very moment it seems the API is just not responding. The online dashboard is working fine, but with the same credentials I'm getting a 502 from the API

Where or how can I set the polling rate in Domoticz?
By inspecting the logs I can tell the polling occurs every 3 minutes, so I should be safe.
Three minutes is probably the default.
However I am still curious where you can change the polling interval in the Domoticz settings/interface?

It cannot be changed, it is currently hardcoded in the plugin (6 heartbeats). The plugin author could add a setting parameter to be able to set polling to x minutes.

I think I figured it out.
After a successful API call, the plugin does 12 heartbeats (10 seconds per beat = 2 minutes). After these hardcoded heartbeats the plugin uses the runAgain variable to determine after how many EXTRA beats it should do another API call. The default is 6 (6 x 10 = 1 minute). So effectively you get an API call every 3 minutes (2+1).
I changed the runAgain variable on line 83 and line 227 to 18 (=3 minutes): so now I get an API call every 5 minutes (2+3).
This can be observed in the logs:

Hello everyone,
I hope I am not intruding as a new user. I found this plugin after configuring my new PV into Domoticz and I can't get the right output I think.
As you can see on the devices page the correct total generation is given (116kWh) but on the dashboard I get a duplication of the current wattage.
Am I doing something wrong? I tried reinstalling the plugin but to no avail.
I was hoping one of you experts could shed light on this?

This is normal behavior, just let it run a couple of days and you will see how it works.

That seems to do the trick. But I still had problems with locking accounts. So I changed the value to 24 today. Now wait and see if that will work better.
