Hi @aukedejong and a big thank you for that!

I don't understand why.
Can you help me?

Perhaps because you have energy saving mode on at night!?

[Martial83]

Yes, you'r right.
Do I have to delete it?
There is no other solution?

[Moosbueffel]

Yes, you can try to switch it off. Id didn't use this plugin, because I have 2 devices, so my device ID is system, which is not supported by this plugin. But I use the same API-call. And I disabled energy saving at night and it works.

So give it a try!

[Moosbueffel]

Other solution is only to disable the calls at night. I think, this can only be done by the developer. Or yoou change the code by yourself.

In my case I also collect the consuption, which is also running during night ;).

[Martial83]

Thank you for your help.
I can't find the option on my fronius

[Moosbueffel]

I checked Settings and manual and also can't find. Perhaps its in the menue at the hardware. This setting was done from my installateur. Perhaps you can ask your installateur if you will not find the setting.

I've found Nightmode, but it is only for the display panel

[Martial83]

No, it's not only for the display panel.
I'll try it

Hi,
I have found the problem:
We must test jsonObject["Body"]["Data"]["DeviceStatus"]["ErrorCode"] rather jsonObject["Head"]["Status"]["Code"] which one is always 0
In addition, I commented logDebugMessage("JSON: " + str(jsonData)) dans getInverterRealtimeData
To be clean, we should test jsonObject["Body"]["Data"]["DeviceStatus"]["ErrorCode"] (307 during night)

def isInverterActive(self, jsonObject):
return jsonObject["Body"]["Data"]["DeviceStatus"]["ErrorCode"] == 0

With the help from this thread I started to modify the plugin a bit so it continues to work for me with the necessary additional checks.
