Amazon Alexa on M5Core2 and M5Core2 for AWS

You can use M5Core2Alexa like using a real Amazon Echo (sometimes, not always). You can ask M5Alexa questions like "Alexa, what time is sunrise?" or ask her into Japanese 「アレクサ、今何時ですか？」, or maybe you can control your lights and fans (I don't have any Alexa-supported IoT devices).

According to Espressif Official, music and radio playback (Audible or Podcast) services are not supported on Non-Amazon-Official products. Unfortunately, Amazon music functionality needs whitelisted product. Only the commercial products are whitelisted by Amazon. Let us know if you are going to commercialise it.

4.2 Alarm Dismiss doesn't take effect.

When the alarm on, you cannot say "Alexa, stop alarm" to dismiss the alarm. I dno't know why... So, if you want to stop the alarm, you can touch the middle "button" on M5Core2. The middle "button" can also wake up Alexa.
