Can I convert to the:
Project repo: GitHub - htumanyan/navien: Navien water heater wire protocol for communication with NaviLink and other attached devices
I try, but the new yaml I try to create and use is not working…any help would be appreciated!
I’d be glad to help if you could share more on what have you tried? in simplest form, if you are compiling from the command line, you can take one of the prebuilt yaml files - navien/esphome/navien-d1-mini.yml at 928d3609a9ce06afcff02706d1a8fcff81a1ba86 · htumanyan/navien · GitHub or navien/esphome/navien-esphome-atom-lite-esp32.yml at 928d3609a9ce06afcff02706d1a8fcff81a1ba86 · htumanyan/navien · GitHub and run esphome run not forgetting to copy secrets.yaml into the esphome folder so that it has your wifi credentials.
Feel free to reach out in PM if needed…
I think I got it in ESPHOME in homeassistant

I guess now I wonder about all the sensors I had before?
You are almost there. Here are a few hints and suggestions:
a. Look at navien/esphome/navien.example.yml at 928d3609a9ce06afcff02706d1a8fcff81a1ba86 · htumanyan/navien · GitHub for an example of how to configure the espbuilder - can copy it from there to your espbuilder and customize.
b. Sensor definitions are moved to separate yaml file (navien-sensors.yml) that are included from platform-specific ones. For example, the navien-esphome-atom-lite-esp32.yml includes it (as well as others).
The sensors.yml is an exhaustive collection of all known and supported sensors.
Does this make sense? Happy to help if not or if anything does not work.
Ahhh…I think I am on the right track…
