not stupid question, I have the same issue.
I’m using proxmox (virtualization machine), and I don’t have acces to this file.
vi /usr/local/lib/python3.9/site-packages/growattServer/__init__.py
From the terminal, it does not search for any location from the growatt directory for me
Well that’s over a week now and still no official fix… any ideas when the next release of HA will be? or is it going to be lumped into the next monthly build? another 10 days away?
<rant> with all the breaking changes and issues with updates taking so long to be pushed out like this I’m starting to get really frustrated with HA, I spend way more time maintaining the system than what it could possibly ever contribute to my life. Don’t get me wrong I love learning, tinkering and the challenge of building things, its just getting to the point of “is it worth it”, so many people are interested in my setup when i get notifications from my cameras with AI highlighting people and cars, or when my air conditioning automatically adjusts based on solar production and full breakdowns of what appliances are costing the most or how much I’ve saved on power bills from having things controlled by HA. but ultimately the complexity of setting it all up and maintaining it is more than most can do themselves. </rant>
this might sound silly, but can the integration be cloned into HACS so we can update without waiting for official updates?
Thanks, it worked to me.
can’t we just read the data from the inverters themselves ?
then we are no longer dependent on chinese webservers !
mine are connected via LAN to my network, why not read them locally ?
or is that a stupid question ?
Its a good question and this video shows how it is possible. Howeder I didnt try yet:
Got a home assistant 2022.6.7 update with growatt installation. Still not working 
When you install the HA core 2022.6.7, the problem is 100% solved. Everything works for me again.
Not for me 
got this error.

I have checked the login details, they are 100% correct.
Does anyone have an idea what is going wrong and how I can fix it?
I have installed the 2022.6.7, but still not working for me. I have tried to delete the integration and install it again, but I get the same error
Just wanted to thank you, after installing the latest core update this morning, everything is back to normal!!!
could add the integration again today! I just entered my credentials and now it connected.
core-2022.6.7
supervisor-2022.05.3
Still unable to load Growatt - supervisor-2022.05.3 , core-2022.6.7
It worked! dad is happy….BUT HA is logging minus 420 kWh, any surgestions?
Works for me too.
Seems to be a problem again:

Anyone else missing data since earlier today ?

Hi, Seems like Growatt have made some changes…
Have a look at this thread on Github for the interim fix on this issue.
Hope it helps…
Uninstalled and installed the application again. Today this was succesful. I did it last time as well but then it had no effect.
I assume the integration changed the last days for the good.
Thanks to the people that replied and big thanks to the people that fixed the integration!
