How do I remove an entity's capabilities?

I have a light which can change light temperature but it’s implementation is very simple: if a light temperature signal is sent, it cycles through the three possibilities.

In HA, this light appears with a light temperature attribute. When I turn the light on, the light turn on but with the next color in the cycle, rendering the experience very disorienting.

How can I get HA to send an ON signal without any light temperature information ?

If all you’re doing is sending a light.turn_on action to the light without any arguments then it’s the light doing that and not HA. Maybe check the lights native app for a setting that’s making that happen.

What make of light? What integration?
