Hello a few weeks ago I started

I'd suggest you don't edit configuration.yaml or automations.yaml, but instead use another file, eg

automation magic: !include my_automations.yaml

https://developers.home-assistant.io/docs/add-ons covers add-on development

Keep in mind you'll also need to trigger a reload of the automations, and if you generate invalid YAML you'll break things 😉

#devs_add-ons-archived can guide with add-on development... probably

yhea u right thanks alot i will try to get user input and make an automation with the input and then write it to a file. But u know how i can manage to write the line code in the user his configuration.yaml file

[tropic carbon]

oh yes indeed need to keep that in mind to

[cyan swift]

You just have to write out valid YAML

That's the easy bit

The hard bit is generating a valid, functioning, automation
