WAMP allows to use the pattern-based subscriptions which should be very convenient for a client, since he can listen to what you want exactly (e.g. only observations from a particular sensor, all observations from a system, etc.).
We could apply the following scheme:
{system_id}.observations.{sensor_id} for publishing observations,
{system_id}.commandresults for publishing actuations.
