Helper entity for "number as profile over a day"

I would like to configure for example the temperature in a room, luminosity of a bulb, or even a simple on/off based on a profile over the course of a day. Basically, what I want is a helper variable which can change over the day using a pre-defined profile, like such a curve:


possibly even be able to use 5min intervals.

I have read that currently there is no such thing integrated directly but there are blueprints which for example provide a number of timepoints to set such a value. Is something like that the only option? Or did I miss something? Sorry if this is the nth post about this but I have no idea how such a thing is actually called :slight_smile:
