.subs

The data item at path /.subs is a collection of all current subscriptions in the DINGO device. Subscriptions are generally created by clients and can be deleted either by the clients when they are no longer needed or by the server when they time out.

Values of BACnet properties can be read by polling values on regular intervals. A more sophisticated method, is to have the values pushed to the client, in the instant the value changes - this is what subscriptions can do.

Visit this page to get detailed information on creating, re-subscribing, deleting and listing subscriptions.
