Need to revisit Television sketch - the latest iOS seemed to have disabled the ability to dynamically set visibility of input sources. Checking/Un-Checking the visibility radio buttons either during pairing, or after pairing on the settings screen, seems to be ignored by the Home App (the same input sources are shown in the selector regardless of any changes made). However, dynamically changing the name of an input source seems to work fine.
Characteristic::ConfiguredNameStatic() is no longer needed since you can now change permissions on ConfiguredStatic to remove PW with removePerms(PW). Updated Television Example accordingly.
To Do: Add getLinks() and setPerms/addPerms/removePerms to API Reference Documentation
This "custom" Characteristic is identical to ConfiguredName() but only allows paired-read and notifications. By excluding paired-write it prevents the user from editing the name of a TV input source from the Home App. This is useful when some sources are fixed, such as "netflix" instead of generic, such as "hdmi 1".
