Is "Works With Alexa" exclusively for devices/skills that implment the Smart Home api?
Thank you for your question.
Your device must integrate with Alexa in one of the following ways:
a) Connected via Alexa Connect Kit cloud services.
b) Connected directly to the Alexa service locally via the Zigbee protocol.
c) Connected and controlled by your Alexa skill that is published in the skill store. If your device does not have an accompanying skill, you must build one with the Smart Home APIs. We will only process applications for certification after your skill is developed and ready to be published.
d) Connected via a secondary device, such as a hub, and controlled by an Alexa skill provided by the hub manufacturer.
e) Connected via a pre-certified IoT service provider, such as Tuya.
