Hello all, since today that my HA can’t connect to the growatt server to retriev data logger info.
If I loggin to server trough web browser to growatt server all data are there.
Already try to remake the integration and still doesnt work.
Any known issue about this?
Thank you all
Hi, same here.
Few HA updates ago it was working. Today I tried to remove and add integration because I didn’t have all entities - since few days I had only a half of them available. But now, I have connected to the growatt server but no power entities are available. After ten minutes new entities showed up. Strange but all entities are available again.
I still have the connect issue with the server. More people having this issue?

Just a few munites ago the server was suddenly connected again.
Growatt server seems to be not very reliable.
In near future I will try to read out the values directly from the inverter with an ESP32 and disable the connection to the Chinese server.
When you setup the Growatt plugin you logon with the same username / pwd as when you access Growatt server page (server.growatt.com)? I’m stuck here, one time I had it working but forgot what I did then, or if I was just lucky not sure…
Yes of course - same Name/PW
@Caddyblack
It doesn’t just seem so, it actually is. 
298 x no connection in 4 days.
There is a continuous WiFi connection to the Growatt inverter and I also have a continuous Internet connection here.
anyone that can make successfull connections since the last week more or less?
Now i have the same problem. No connection at all has been possible via Home Assistant for ~ two days.

Same here, upgraded my system at dec 26 2022 form 2022.12.4 to 2022.12.8 , sinds then no connection.
Just attempted the 2022.12.9, didn’t work.
Also tried a clean install (no restore) on a rpy, same error. Cannot connect to the server.
When i add a new intergration Growatt, i see >> https://server-api.growatt.com/
Can be wrong but, i tought i saw before >> https://server.growatt.com/
Those have different IPnumbers on the internet, is it possible the connections goes to the wrong server?
I have the same issue. I don’t get it, it’s been broken more than it’s been working since this summer now 
What changed?

… this isn’t an issue with HA it’s an issue with Growatt keep changing things to block the API calls.
Seems it is happening again as I have no information on HA today but the Growatt website works fine.
Very frustrating

Same here, Unknown error occurred.
Same login works on https://server.growatt.com/
Any help appreciated! 
Can confirm, same error on a new install HA 2023.10.1 Supervisor
Same here, all working on https://server.growatt.com/ with authentication data, but the integration keeps showing me an “Unknown error occured”.
Any resolution for this?
moin,
the integration points to a different url it displays → https://server-api.growatt.com/
my login goes to this url and works fine for me in my browser —> https://server.growatt.com/
ithink that will be the error … iam new to this , who is responsible to fix this fault ??
thank you rtax
As a new user bumbed to this thread. Trying to setup access. Any pointers to try? Can code if need but thought that this is well functioning software…
