You cannot use **random** keys with the `cloud variables` as listener.

Last time I spoke to the developers, in the last community meetup, they said they are working on enhancement to the way cloud variable deals with Firebase.

I do not know exactly what kind of enhancement there will be but let’s stay positive.
