Homeassistant integration

The integration into Homeassistant is enabled by default. You could enable/disable the functionality by (un-)commenting the "#define ENABLE_HOMEASSISTANT" in "definitions.h". It uses the ArduinoJSON library, so you have to install it also via "Library Manager", when you want to use the integration.

MQTT topics

When you have Homeassistant integration enabled, there are three additional topics available:

• home/HOSTNAME_ha/state/in
• home/HOSTNAME_ha/state/out Where HOSTNAME is the current hostname set in definitions.h.

in-topic format

The in-topic consumes JSON formatted data with the following structure:

{
	"brightness": 196,  
	"color": {  
		"r": 255,
		"g": 100,
		"b": 10
	},
	"speed": 194,
	"color_temp": 24,
	"effect": "Rainbow",
	"state": "ON"
}

in-topic parameters

• brightness: Value 0 - 255
• color: Structure with Red (r), Green (g) and Blue (b) values 0 - 255
• color_temp: Color temperature in mireds
• effect: Name of the effect like defined in WS2812FX - case sensitive.
• state: "ON" or "OFF"
• speed: Value 0 - 255

out-topic format

Contains the current mode as JSON.

Example:

		"r": 255,
		"g": 86,
		"b": 0
	},
	"speed": 194,
	"color_temp": 24,
	"brightness": 100,
