This document discusses how to connect smart home devices like PlayBulb to voice assistants using IFTTT and Watson IoT Platform. Devices can publish events to WIoTP which then trigger IFTTT recipes. IFTTT uses webhooks to send commands to devices or trigger Alexa/Google Home. Node-RED flows show how commands from voice assistants can control devices via WIoTP, IFTTT, and MQTT. References provide code and recipes for setting up the connections.
