Light control
This skill implementation follows steps explained on the intro page to enable light control.
- Turn light on / off
- Set light’s brightness
- Set light’s color temperature
Add intents
[ChangeLightState]
light_name = (wohnzimmerlampe | garagenlicht){name}
light_state = (ein | an | aus) {state}
schalte (die | das) <light_name> <light_state>
licht <light_state>
[ChangeBrightness]
(stelle | setze) [die] helligkeit auf (1..100){percent!int} [prozent]
[ChangeTemp]
(stelle | setze) [die] temperatur auf (kalt | warm){temp}
Example sentences
1. stelle die wohnzimmerlampe aus (turn the living room lamp off)
2. stelle die helligkeit auf 10 prozent (set the brightness to 10 percent)
3. stelle die temperatur auf warm (set the temperature to warm)
Node-RED flow creation
Features for your smart device can be found here. Aqara LED Light Bulb supports the following features: state, brightness & color_temp.
The web socket in node waits for an intent to be spoken. After an intent is recognized a json structured payload is passed to the first switch called check intent. This switch passes the information to the next node depending on the intent name associated with the spoken intent. All template nodes contain json formatted statements to control features of your light bulb.
The set brightness function node contains javascript code, which scales the passed percentage to fit the lights brightness scale.
var val = 255 / 100 * msg.slots.percent;
msg.payload = {
"state":"ON",
"brightness": val
};
return msg;
Put the address of Rhasspy’s internal MQTT broker <pi's-ip>:12183 and your lights ZigBee topic zigbee2mqtt/FRIENDLY_NAME/set into the mqtt out node to enable communication with your smart device.
Download the json file associated with this flow and import it into Node-RED using the header menu to get a deeper look into this skill.
