PPM characteristic not shown in EVE app

[thncode]

I think you could still be using the short names by including them in this.signatures, instead of the uuid. Would probably need to split up status, though.

The missing UUIDs:

• PPM: https://github.com/ebaauw/homebridge-lib/blob/b2c7f4e69d2b4b7ef4b3846c9de4c8b981ef84df/lib/EveHomeKitTypes.js#L161
• Open / Close: ContactSensorState

@ebaauw ist there any precondition that must be defined?

For the Eve Room v2 I've figured out the correct way to show the graphs for ppb, not ppm.
The PPM based graphs also worked for me, but only with the Eve Room v1. Changing Eve's PPM characteristics also changed the Stars in the Eve app. As i remember this PPM characteristic only changes the Stars and didn't show any values (maybe for the graphs).

Since the new Room has different sensor ( SGP30, instead of AMS), Eve changed the graph from ppm based measurements to ppb and the Stars are now based on VOC readings (in ug/m3 so ppb needs to be converted) instead of the first gen Room's Co2 / ppm based measurements.
