Create template-sensor through API?

VolkerStolz · February 22, 2024, 3:18pm

I am looking for a way to configure a new template-sensor programatically. That is, I neither want to somehow touch configuration.yaml, nor manually click through the GUI-based dialog.

If I have all the options that I would need to configure for a new template via either mechanism, is there a way to do so e.g. through the API from the outside? Maybe I should check how “Repairs” work?

As background-info, I’m kind of developing a setup-assistant.

Thanks in advance for any tips & pointers! The keywords are unfortunately too overloaded so that I did not spot any existing info.

I don’t know if there is such API but there is a way to separate your configuration from other configurations: Packages - Home Assistant

Thanks, that’d be a partial solution but I’m looking for one that requires no user-intervention.

See below link for some pointers. I wrote this as a custom template helper via UI just before it was included in the core.

Basically create a SensorTemplate entity in your code.

Not possible. You have to touch yaml files. There is no API for HA to create sensors & entities on the fly outside websockets. And websockets don’t handle the config entry generation.
