Cannot enable integration on Home Assistant OS

[bengeek2]

I have added the entry "crestron: port: 45000" and all other entries for switches/sensors to my configuration.yaml. I have not received any errors, and I fully rebooted the OS. All entities have appeared but they are listed as unavailable. I cannot see the Crestron integration in my current list. If I click "add integration", it is in the available to add list, but clicking the add button responds with "This device cannot be added from the UI You can add this device by adding it to your 'configuration.yaml'. See the documentation for more information."

My configuration.yaml is:

# Loads default set of integrations. Do not remove.
default_config:

# Load frontend themes from the themes folder
frontend:
  themes: !include_dir_merge_named themes

# Text-to-speech
tts:
  - platform: google_translate

Check your firewall. Items were unavailable as i was blocking traffic between HA and the processor. The integration doesn't show up in the list, but all entities are present and working.
