V-switch exposed to Echo via Emulated Hue does not show up in routine as device

Configuration
1

This is my config:

emulated_hue:
  listen_port: 80
  expose_by_default: false
  entities:
    input_boolean.echo_nap_time:
      name: "Echo Nap Time"
      hidden: false

The device shows up in Echo device list as a light switch, but when I try to create a routine, it does not show up as a device from which I can pick. Any idea why?

Thanks.
