The procedure is as follows: (1) Download the Botslab app from Google Play or iOS App Store. (2) Open the Botslab app to register or log in to the account. (3) Turn on a smart device and connect it to the Botslab app. (4) Rename the device used for voice control. For example, you can rename "bulb" as "living room lamp", so that you can speak "turn on the living room lamp" to control it. (5) Download the Alexa app from Amazon Market, Google Play, or iOS App Store. Connect Echo to the Alexa app. (6) In the Alexa Skills directory, search for Botslab. Enable Botslab functions and authorize account login. (7) Speak "Alexa, discover the device" to Echo. When the Echo responds "discovery completed", you can control your devices by voice.
