Error when using inverter_id

[WynandPrivate]

I'm trying to get details from my inverter, but the inverter ID I'm using is giving me the following error message:

{'msg': '501', 'success': False}

I'm using the inverter ID that is displayed on the web page of the Growatt server:

test = api.inverter_data('NAC5A142E4', datetime.date.today())

Could you try using the deviceSn that shows up if you run: api.device_list(plant_id) Maybe the alias (which is what shows up on the website) differs from the inverter ID

I have the exact same issue. I used the deviceSn that shows up when I run api.device_list(plant_id) Also tried it with the deviceAilas and the datalogSn, I even removed the spaces I had in the alias, but the response is always {'msg': '501', 'success': False}

Any help would be appreciated.

Are you certain it is only an inverter and not a different device? e.g. mix/hybrid, battery You can do so by checking the deviceType

Hello! Encountering the same issue:

1. Get inverter ID with api.device_list(plant_id), confirmed deviceType='inverter'
2. Using deviceSn from step one in api.inverter_data gives {'msg': '501', 'success': False}

Hmm after some digging it could maybe be a username/password issue as well https://github.com/DiedB/Homey-SolarPanels/issues/105#issuecomment-654303602

Could you maybe try changing your password and see if this fixes the issue? Maybe they changed their way of storing passwords after you created your account

Same problem here, tested in 4 different inverters. I'd like to create a dashboard that integrate the day generation of each inverter in a month and report by email. Anyone got successful to get the daily generation of the month?
