SOLVED MMM-Alexa Current Issue
Alexa api V1 will ended very soon
Mail from amazon:
Amazon is deprecating the Alexa Voice Service (AVS) developer preview v1 API. To prepare for this deprecation and ensure your connected products continue to connect to Alexa, you will need to stop using the v1 API, and begin building using a newer version of AVS Device SDK or either by using open APIs given here - API v20160207. We will deprecate the v1 API on September 30, 2021.
The AVS v1 API includes features released in 2015. The v1 API supports a limited number of new features and has no persistent down channel. In 2016, Amazon introduced API v20160207, which is designed to support new features added to the cloud-based voice service. We also released the AVS Device SDK in 2017, making it even easier to build voice-forward products that connect to the AVS cloud.
You will need to stop using the v1 API, and starting building with a newer version of AVS Device SDK or either by using open APIs given here - API v20160207. Following the depreciation on September 30, 2021, your connected devices using the v1 API will no longer retain connection to Alexa.
So, I will code recode it very soon (With Visual ?) with new API
