![]() ![]() For this project, we only need the sending capabilities we don’t care about IR receiving. You’ll need to wire this to your ESP8266 chip, and this you’ll have to do yourself. You can get them on Ebay, or just about any well-stocked hardware shop online. They cost about just a few USD at the time of this writing. ![]() The Alexa device costs pocket money, but use of the Echosim is free. Give it a try if you’re feeling adventurous (or frugal). Will the tutorial work with an Echo simulator? It might! (But I haven’t tested it). I’ve developed this tutorial with an Alexa Dot. To complete this tutorial, you’re going to need to obtain some items on your own, all of which are easy to obtain. Handle them by sending IR codes through the IR transmitter, turning our TV on/off. Once trusted by the Alexa device, listen for further commands from said device.Listen on the ESP8266 for the Alexa device sending out probes on the local wifi network for compatible devices, and respond to these probes by saying “I’m a Wemo.”.Basic Plan for our ESP8266 Arduino Tutorial Pretending to be a Wemo, our ESP8266 enjoys the privilege of being able to receive commands directly from the Alexa. We are going to make our ESP8266 “emulate” a Wemo Belkin, a device that has a special license with Amazon allowing it to communicate directly with the Alexa device, bypassing all of that Amazon cloud communication described above. We want the Alexa to directly send a request to our ESP8266, over and inside of our home wifi network only. ![]() We want to make the Alexa device talk directly to our ESP8266 chip, inside of our home, without sending anything out to the cloud and back. In the case of Alexa IoT, the command gets routed to a “device shadow” on Amazon’s cloud, which in the end results in a response being sent to some other device in your home. The Alexa “skill” takes over handling of the command normally it results in a response being sent back to the Alexa device, causing it to say something to the user in response.
