Thanks for this guide! Currently I’m only able to use Docker based Home Assistant, and it does not support Add-ons. I was able to install ESPHome using ESP Web Tools, but couldn’t figure out how to upload lilygo-t-can485.yaml file to the board.
Is it possible to install/upload this yaml without HA OS, i.e. using container based HA installation or some other method (maybe ESPHome on Docker)?
EDIT: ESPHome on Docker did the trick!
