====== c-beam MQTT ======

MQTT is a machine-to-machine (M2M)/"Internet of Things" connectivity protocol. see: http://mqtt.org

We are running a mqtt server on c-beam.cbrp3.c-base.org on port 1883. It's only reachable from the internal network.

Currently there are the following topics:

^ topic                 ^ interval ^ description ^
|info/time              |  1 minute  | current date and time |
|c_out/loop             | 10 minutes | starts a new sound loop on c_out |
|c_out/play             |  n/a       | playload plays various sound samples |
|c_out/Julia            |  n/a       | playload plays announcements on c_out via tts with voice Julia|
|nerdctrl/open          |  n/a       | opens the payload URL in a browser in the nerdarea |
|client/echelon         |  n/a       | this is a retained topic, if it is available, the traffic stats script on echelon is running |
|system/echelon/traffic |  1 minute  | average incoming and outgoing traffic on ipb and kdg lines from echelon in bytes/s since last message |
|ingress/status/+       |  n/a       | these are retained topics and show status of the ingres portals around the c-base |

====== mqtt-sender ======

The topics from echelon are published with a small lua daemon, which can be easily extended.
