Hi,
After recent updates to esphome in home assistant my YAML file no longer works because they have deprecated custom components under this ESPHome 2025.2.0 - 19th February 2025 — ESPHome
To be replaced with External Components under this
External Components — ESPHome
I currently have a yaml file which references another file that reads the output of xantrex solar inverter, however no longer works due to the deprecation.
I have no idea on how to convert to an external component and have tried ChatGPT with no luck. Any help would be greatly appreciated
The code for my files are as follows, which was working prior to the update
esphome-web-fc1ed5.yaml
