A garden at night looks great with effective lighting. Even better when the light listens to the word. Say "Alexa, trigger garden lights" and this applet sends "Switch on" to a Timberwolf Server object, which then switches on the garden lights via KNX. Or also DMX, MQTT, HTTP. If you want to say and switch something else, just create a new applet. Start with Alexa, define the words to be reacted to and have it sent to your Timberwolf Server.
