Is it possible to add support for any custom characteristic ?

[faronov]

I think this will be a good idea for the roadmap
just add a possibility to create any custom characteristic
like add any UUID type and name for that?
it will be allowed to add any custom characteristic to EVE app.

You can check an example of how it can be extended
that will add the possibility to create any services and any accessories

Please see: https://github.com/KhaosT/HAP-NodeJS/blob/master/lib/Characteristic.js#L21

Shouldn't be difficult to integrate, i.e. probably just setting a custom UUID.

An example of an custom characteristic AtmosphericPressureLevel can be found here: https://github.com/rxseger/homebridge-bme280/blob/master/lib/CustomCharacteristic.js#L12

@faronov @fschaefer
I finally made up my mind to look at this and add it in near future.

How do you see it to be used actually?
Is it for using Eve? Or other apps?
How do you see adding custom characteristics?
Should we add them to code or allow users to add them?

Bump. Your opinion is important for me.

[faronov]

Currently this available for Eve, not sure about other apps
I think we must allow a user to specify any UUID for custom characteristic and add details

[Shaquu]

Can you make an example of such? I mean details of custom characteristics.

check this
https://github.com/RavenSystem/esp-homekit-devices/blob/master/devices/common/custom_characteristics.h#L27
it has a bunch of custom characteristics
