Elgato Eve shows Inactive appliances as though they are in an error state

[thoukydides]

When an appliance is idle, the Elgato Eve app presents it as though it is in an error state. On the summary screens it shows a red warning triangle with an exclamation mark, and on the detailed screens it shows the status icon in red with the message:

The accessory is inactive. Please refer to its user manual.

This is annoying. It appears to do this based on the Status Active characteristic being set to false (even if Active is INACTIVE and the Status Fault characteristic is NO_FAULT).

The HomeKit Accessory Protocol Specification describes Status Active as:

This characteristic describes an accessoryʼs current working status. A value of true indicates that the accessory is active and is functioning without any errors.

This plugin currently maps BSH.Common.Status.OperationState to HomeKit Characteristics as follows:

Operation State	Active	Status Active	Status Error
Inactive	INACTIVE	false	NO_FAULT
Ready	INACTIVE	false	NO_FAULT
DelayedStart	ACTIVE	false	NO_FAULT
Run	ACTIVE	true	NO_FAULT
Pause	ACTIVE	false	NO_FAULT
ActionRequired	ACTIVE	false	NO_FAULT
Finished	INACTIVE	false	NO_FAULT
Error	ACTIVE	false	GENERAL_FAULT
Aborting	ACTIVE	false	NO_FAULT

A different mapping may work better.

If this is changed, then it is probably also worth considering using the Active characteristic to control program pause/resume (or stop) for appliances with those capabilities. This plugin currently configures the Active characteristic as read-only, but this can be changed to read-write where appropriate.

This was originally raised by @DJay-X in issue #1.

Testing how the various HomeKit apps show different status characteristics...

Active	Eve	Home+
INACTIVE	OFF	Inactive
ACTIVE	ON	Active

Status Active	Eve	Home+
false	Inactive: The accessory is inactive. Please refer to its user manual.	No
true	(not shown)	Yes

Status Error	Eve	Home+
NO_FAULT	(not shown)	No Fault
GENERAL_FAULT	Fault: The accessory reports fault code 1. Please refer to its user manual.	General Fault
42	Fault: The accessory reports fault code 42. Please refer to its user manual.	42.0

Program Mode	Eve	Home+
NO_PROGRAM_SCHEDULED	MANUAL	Program not Scheduled
PROGRAM_SCHEDULED	SCHEDULE	Program Scheduled
PROGRAM_SCHEDULED_MANUAL_MODE_	OVERRIDE	Manual Mode

Additionally, Eve shows the InUse characteristic as a water drop animation so that is not generally suitable.

Neither the Apple Home app nor Hesperus show any of these characteristics.

The mapping from BSH.Common.Status.OperationState to HomeKit Characteristics has been changed to:

Operation State	Active	Status Active	Status Error
Inactive	INACTIVE	true	NO_FAULT
Ready	INACTIVE	true	NO_FAULT
DelayedStart	ACTIVE	true	NO_FAULT
Run	ACTIVE	true	NO_FAULT
Pause	INACTIVE	false	NO_FAULT
ActionRequired	INACTIVE	false	NO_FAULT
Finished	INACTIVE	true	NO_FAULT
Error	INACTIVE	false	GENERAL_FAULT
Aborting	ACTIVE	false	NO_FAULT

This should work better with the Elgato Eve app.
