lifx-mqtt

Only allows for updating light state at present. Doesn't publish any events when light state is changed elsewhere. In the future will look at adding some events under /status.

Lights should be autodiscovered and logged. Check the output to see available IDs.

Topics

With a prefix of lifx, the following topics can be used:

• lifx/set/{id}/on
• lifx/set/{id}/off
• lifx/set/{id} - sets the light state based off the body data (JSON). Fields are brightness, temp, color, duration

Examples:

• Topic: lifx/set/d073e429c362
