Hi Guys,
I’m making this blanket post in loads of different locations, but just so you’re in the loop, I’ve just made a big post over here: Growatt Integration - Roadmap (see the original post and my latest comment) about moving the integration out of home assistant core and into HACS.
If some of you are still interested in using it, please take a look at the new incarnation of the integration (it’s currently identical to the version available in Core but will diverge in the next few releases), then please go ahead.
If you can’t be bothered to read the other post, just take a look here: GitHub - muppet3000/homeassistant-growatt_server_api: Home Assistant Integration for Growatt - Replacement for the original growatt_server integration that used to be part of the core Home Assistant repository
