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.
All tutorial examples now updated and confirmed working s expected in ios15.4.1 except for Example 17 (Shower). DEV_Identify.h removed from all examples and optional AccessoryInformation() Characteristics deleted to make examples easier to use and understand.
To Do: Review and update "Other Examples" and add link to Example 19 in Tutorials.md
This appears to be a Home App problem. The problem cannot be fixed by adding in ServiceLabel and ServiceIndex (no impact), nor adding in isConfigured(), nor adding Name() Characteristics. The Home App refuses to render the valves regardless of what valve type. They will sometimes appear, and then disappear from the interface for no reason.
Testing with the Apple's HomeKit Simulator yields the same symptoms.
Completely replaced Example 11, which showed how to use setPrimary() since this no longer seems to have any impact on HomeKit. Changed sketch name from ServiceOptions to ServiceNames.
