Insteon Ceiling Fan Module - Change Light Only

I have an Insteon Hub 2 and an Insteon Ceiling Fan Module 2475F and an Insteon 6-button keypad. I want to create a scene which sets the light to 60% but does not change the fan speed. How do I do that?

I created a scene and added the fan controller device. That automatically included both entities: the light and the fan.

I tried adding the fan controller light entity and that added the device, with both the light and fan entities.

Since the fan entity exists, I have to choose a fan speed (off/low/medium/high) and there is no choice for don’t-change-the-speed.

Answering myself: I wrote the scene manually in YAML. Problem solved.
