In addition to the HomeKit accessory implementing the lock service I’d like to have a contact sensor service for the same accessory or a new additional accessory with contact sensor service, using data from the magnetic door sensor.
Reason
We can use the HomeKit contact sensor to monitor the status of the door, get notifications and make automations.
Examples
Get a notification when the door is actually opened and trigger automations, i.e. setting off a siren if a security system is in “Away” or “Night” mode or turn on a welcome light.
Yeah, I know, I am a homebridge (and Tasmota, RavenCore, HAA, etc.) fan/advanced user so I’m not restricted to native HomeKit sensors, i.e. I integrated z-wave in my setup, but… c’mon, it’s there, let us use it
Is the door/contact sensor ever coming to HomeKit?? I use homebridge and could use the webhooks with a plugin to only expose the door sensor but I’m trying to rely less, not more, on homebridge.
As often with HomeKit the problem is not Nuki but the HomeKit specification: It does not know and allow locks with integrated door sensor. Therefore the door sensor would need to be a separate device exposed by the Smart Lock to HomeKit, which is not possible because only bridges can expose several devices.
But there are accessories that expose multiple services right? For example, a temperature sensor often exposes humidity and such. A camera typically exposes motion sensors as well, and so on, all without additional bridges.
What’s the limitation behind the lock exposing a contact sensor when compared to other accessories?
