mqtt-dmx-sequencer's Issues

Set universe

Hi, is it possible to set the universe?

Broker not using the sequencer?

Hey @hobbyquaker
So if i lay out what I'm trying to do, I have OLA a DMX node running ARTNET and I'm trying to get a light turn on from my iPhone to the OLA Artnet node, Through homebridge sending MQTT to your mitt-dmx-sequencer.

When ever i try to run mqtt-dmx-sequencer i just get this back:

artnet.data[0] = [];
               ^

TypeError: Cannot set property '0' of undefined
    at Object.<anonymous> (/usr/local/lib/node_modules/mqtt-dmx-sequencer/index.js:22:16)
    at Module._compile (module.js:410:26)
    at Object.Module._extensions..js (module.js:417:10)

    at Function.Module.runMain (module.js:442:10)
    at startup (node.js:136:18)
    at node.js:966:3

I have had no issues getting the connection between homebridge and the MQTT broker but i can't for the life of me figure out how this sequencer is meant to work, is there an npm start for it or something like that, because right now its just sitting around with all of its config in order looking pretty, any help would be amazing!

Im currently running Ubuntu 16.04 Server LTS with node version v7.4.0 and NPM version 4.1.2.
I have check through MQTT.fx that the information is getting to the broker and it is, its just an issue between the broker and the sequencer.
