ERROR Error while reading config: Invalid YAML syntax:

Hi, thanks for the hard work, I just bought the atomS3 with mini can to replace my previous ESP32 that have many problems.

I'm blocked and I'm not able to compile and install the files onto the atom.

Do you have a small tutorial on how to do it? Sorry I'm pretty new ESPhome.

I tried to compile with esphome via CMD but I have this error:

C:\Users\Pierre\Downloads\esphome-zehnder-comfoair-main\esphome-zehnder-comfoair-main>esphome upload zehnder-comfoair-q-m5stack-atoms3.yml

Ok finally I managed to install it on the board, I use GIT CMD (software to download for windows) And I called the command : esphome compile zehnder-comfoair-q-m5stack-atoms3.yaml.

I had to change the name of the extension file to .yaml so it would comile and uplaod on the board.

Not easy when you are new to this esphome world :-)

I am having the same issue but I'm on a Mac.
Did you have to add any other software other than burning the Atoms3 to begin with?
I have mine burned, connected to the Wi-Fi, but unable and unsure what to do next to get the files from git onto the atom. Any help appreciated.

I only used Git CMD from this website (https://git-scm.com/downloads) to compile the yaml file that I downloaded from git. I needed to install visual studio as some libraries I think from there are needed.

1st step - downlaod zip from git of the project
2nd step - download GIT CMD & visual studio and install on your computer
3rd step - rename m5stack file with .yaml extension and complete the secret.yaml files with your wifi credentials
4th step - open GIT CMD and navigate to the repertories where you have the yaml file.
5th step - compile file with this command line : esphome compile zehnder-comfoair-q-m5stack-atoms3.yaml
6th step - upload file to your atoms3
Connect to your VMC and enjoy!!!! :)

FYI I had to remove the ota lines inside the base.yml from package folder.

I'm sure their is a better and simpler way, but it's the one I found that worked for me after hours of try and error.

Hope this help.
