I followed the example in the documentation and implemented the Power Control API with a node.js Lambda function. The Smart Home skill I created for turning device on and off is working fine with my smart light switch. However, it seems odd that:
1. Alexa does NOT respond with "OK". It only responded with a two tone sound. Is this normal?
2. I read from another thread saying that the "Output Speech" cannot be customized with Smart Home Skill. Is that still true?
3. When I test it in the Alexa Developer Console, the "Skill I/O" section doesn't show the JSON request/response at all. On top, I only see it displaying "<Audio only response>". Is this normal?
Thanks in advance,
