Emulated Hue, input_boolean and Amazon echo, echo complains device isnt responding

Configuration
1

Hi Everyone,

I have setup 2 automations that are triggered by an input boolean to turn my tv and stereo on and off which works well.

I have then set up Emulated to to publish my input boolean:

emulated_hue:
  listen_port: 80
  host_ip: 192.168.1.33
  expose_by_default: false
  entities:
    input_boolean.tv:
      name: "TV"
      hidden: false

When I ask the echo to turn on or off TV, it works but the echo complains:

"Tv isnt responding please check its network and power supply"

Any ideas how to resolve this?
