Iam a noob in this field,
1) I would like to know how device manufacturers normally implement alexa connectivity to their devices.?
2) Does it require a mandatory cloud connectivity from the device manufacturer side for the device, Or Can it be done locally in the clients Wi-Fi network with out any cloud facility.?
3) What all are the best practices for the above implementations?
4) How Alexa finds the devices in the WiFi network. What protocol is being used for the discovery process.?
