Disable ThirdReality presence sensor R3's light

I just got a presence sensor from ThirdReality, and it has an RGB light on top.

The light seems to have some built-in automations, but I don't want to use them! For example, I don't want it to flash blue whenever someone enters the room. Does anyone know how to disable it?

What I've tried:

  • Setting an automation to turn off the light when occupancy is detected. It still flashes for a second.
  • Setting all the option values to 0.
  • Setting the start-up color option to 0. It can't go below 153.

Here are the options:

Sorry, I initially marked that as the solution without checking. That instruction is for a different product.

My mistake, thought it was the same device.
