Support sensor config

[ebaauw]

Currently homebridge-hue only supports the on, battery, and alert sensor config attributes, where on maps to StatusActive, which is readonly in homekit, battery to BatteryLevel and alert to Identify, which is write only in homekit.

I wanted to support enabling/disabling a sensor from homekit, by mapping on to a homekit On characteristic. However homekit doesn't support multiple characteristics of the same type for one service (which would be needed for enabling/disabling a CLIPGenericFlag or supporting additional boolean configuration parameters, like ledindication and usertest. Homekit does support multiple services per accessory, but this seems to confuse most homekit apps.

to enable or disable sensor i installed the other repo plugin homebridge-huesensor, it can do the trick, don't know what's the difference between yours plugin

Hi @sommo
As far as I can see, they don't expose the sensor value itself. They only support enabling/disabling the sensor. Therefore they don't run into a conflict of multiple On characteristics per service.

HomeKit now provides a read/write characteristic Active in addition to the read-only Status Active.

v0.1.8 uses Active to enable/disable a sensor - no need for an additional service for a (potentially) second On characteristic. Next to the new Active, Status Active is still used, so Eve alerts the user that the sensor has been disabled.

Since recently, Siri also sets the Active characteristic off (in addition to the On characteristic), when askied to turn off a room, effectively disabling all sensors.

To avoid this, v0.2.0 uses a custom characteristic Enabled instead of Active.

In v0.2.0, BatteryLevel is exposed in a separate BatteryStatus service, consistent with Apple's iOS 10.3 Home app. This service also includes mandatory characteristics StatusLowBattery and ChargingState. The threshold for low battery can be set in config.json. ChargingState is always Not Chargeable.

I'm closing this issue now, as I have no plans to support the other config attributes.
