How to change "available/unavailable" state for the Home Assistant entity?

I thought the state would change if set the state:

apps.yaml:

light_center5:
  module: LightController
  class: LightController
  virt_light:
    - entity_id: light.virt_light_template1

LightController.py:

self.virt_light = self.args["virt_light"][0]
self.set_state(self.virt_light["entity_id"], state = "on")

virt_light_template1 state changes in Home Assistant, but virt_light entity is not visible to AppDaemon. As a result, the AppDaemon script is silent (does not write anything in the logs and does not execute the program)
