DALY BMS (k-type) support for ESPHOME ? #1

Unfortunately I couldn't find where else to write, so I'm writing to a similar project.

Please make DALY BMS (k-type) support for ESPHOME. Home assistant has a working project (https://github.com/patman15/BMS_BLE-HA) - but it's only for HA, and I'd like to use it together with OpenHab.

Do you have a working setup? So your BMS is accessible via BLE and you could provide some testing?

@kirillch2000 I've prepared a first draft. Do you like to give it a try?

Thank you very much for responding to my request so quickly!

I tried your component - the result is as follows. All 3 of my DALY BMS (2 new - k-type and 1 old - last year's model) - work perfectly and give all the parameters! So this draft should be considered working!

Could you provide some more details about your DALY BMS models/versions? I would like to mention the devices as supported at the README. Could you tell me the BLE name of each device?
