The lamp supports several visual effect which are specified in the configuration. Code of all effects are in the class DeviceControl in files DeviceControl.h DeviceControl.cpp. The mqtt topics is configured in Config.h. As a payload of mqtt messages the lamp sends JSON documents. The structure of the document which the lamp sends every INTERVAL_PUBLISH_STATE milliseconds is:
{
"state": "ON",
"effect": "EffectName",
"brightness": 255,
"color": { "r": 255, "g": 255, "b": 255 },
"transition": 10,
"ip": "192.168.1.110",
"mac": "11:22:33:44:55:66",
"rssi": "-67",
"uptime": "12:23:33"
}
The command JSON document is similar to the one which is shown above. For example, if it's required to turn on the lamp at the red color with 50% brightness, the JSON document will look like:
{
"state": "ON",
"brightness": 128,
"color": { "r": 255, "g": 0, "b": 0 }
