wow great... need some PR asap to avoid more code conflicts

Hi, i'm very interested in this project and willing to help.
I was trying to use it for Anenji 6.2 (blue one, no parallel)
Seams it's clone of EASUN SMG II

I couldn't use code from bigdigital (compiled and upload to Wemos D1 mini)
Using ESPHome component - https://github.com/syssi/esphome-smg-ii worked fine, but it's laggy and not stable (i spent 3h on configurating yaml... not to face OOM)

https://github.com/softwarecrash/Solar2MQTT/pull/174/files - created PR with @bigdigital (main kudos to Artem !) and added more info from provided pdf.

here is my esphome config:

Hi, i'm very interested in this project and willing to help.
I was trying to use it for Anenji 6.2 (blue one, no parallel)
Seams it's clone of EASUN SMG II

I couldn't use code from bigdigital (compiled and upload to Wemos D1 mini)
Using ESPHome component - https://github.com/syssi/esphome-smg-ii worked fine, but it's laggy and not stable (i spent 3h on configurating yaml... not to face OOM)

https://github.com/softwarecrash/Solar2MQTT/pull/174/files - created PR with @bigdigital (main kudos to Artem !) and added more info from provided pdf.

here is my esphome config:

Hello,
Thanks for your Work, but badly its for the wrong Branch.
Actual i Work on the rework Branch and Change a Lot of Things.
So the whole Thing from bigdigital needs to implement in this Branch.
When you Like to do this you can Join the discord Server and write ne for more Details.
