So I’ve created a number helper with automation that updates the value between 250 to 454 to represent color temperature.
That automation trigger is based on time and so every hour the value is being updated.
Now I would like to wire that number to all my lights so when I turn them on, they turn with the correct color tone based on the time + I would like to actively push that value to already on lights.
What would be the way to approach such a solution?
Is there a regex way to select all entities that start with light.* ?
Thanks
