Hidden Hikvision Binary Sensor Entity Error

Hi, any idea why I get the following error when trying to mark the tamper sensor as hidden?

Error:
2018-03-11 14:08:32 WARNING (MainThread) [homeassistant.config] Package living_room contains invalid customize

Only “binary_sensor.living_room_sensor_tamper_detection” is causing the error, the same applies for each of four “binary_sensor.XXXXXX_sensor_tamper_detection”, if I exclude it, there is no error.

Package contents:

homeassistant:
  customize:
    binary_sensor.living_room_sensor_field_detection:
      hidden: true
    
    binary_sensor.living_room_sensor_illegal_access:
      hidden: true
    
    binary_sensor.living_room_sensor_tamper_detection:
      hidden:true

Lack of a space after the colon?

Geeeeeeeeeeeeez!

I guess that’s what happens when you look at yaml for too long :joy:, been trying to figure this out for the past couple days.

:+1: :beers:
