MQTT has no 'declared' topics. The only way to know whether a topic exists (is spelled correctly) is to subscribe to it and see if a message turns up.
Obviously, on the public test server it is recommended to use unique topics.
The sensor example uses DEVICEID_sensor_data and DEVICEID_sensor_ctrl for the channels (automatically added).
