Maybe it can help you (and me ;) )

https://github.com/Adminius/esphome-yaml-collection/blob/main/deye_rw-m6.1.yaml

but I don't have the batteries any more, so can't work on it anymore.

Hi

Yeah... this is awesome! :)

I was just contemplating making use of a spare ESP32 and MCP2515.

[EDIT] : read through esphomes canbus docs, seems pretty simple :)

Thank you!

I made use of the MCP2515 after all :)

MCP2515 => 250K for InterCAN bus ESP_CAN => 500K for PCS bus

I will post an updated yaml for this repo, since now there is no real need for other devices :P

Thanks for the prompt in the right direction and the work on the yaml file.

Cheers
