Hey there @indykoning, @muppet3000, @jasperplant, mind taking a look at this issue as it has been labeled with an integration (growatt_server) you are listed as a code owner for? Thanks! _{^{(message by CodeOwnersMention)}}

I think this is a duplicate of: #76453 please can you close this one and follow the thread over there instead.

I have an issue with adding the Growatt to home assistant. After the username and password it creates the integration, but no entities. I have no logging.

[BaukF]

Same issue here, tried to poke around for the workaround, but can't seem fix it.

[muppet3000]

See other ticket, as I said above.

I'm not going to respond to anything over here, there's another thread with lots of feedback on this issue over here: #76453
