<p >I've always wanted to have a Smart AC so I can turn it on when I'm on my way home and arrive to a cool place. I couldn't just use a smart thermostat because I don't have central Air. I instead modded my AC's remote to be triggered by an Arduino. </p><p >The general steps are as follows: </p><h3 >Remote Mod / Arduino Setup</h3><ul ><li >I modded my AC remote to always have the power button pressed</li></ul><ul ><li >I removed the remote's battery and connected it to Arduino</li></ul><ul ><li >I included 2 LEDs. A red one to tell me when the project was online and a green one to tell me when the button had been triggered</li></ul><h3 >Adafruit & Arduino IDE Code</h3><ul ><li >I created a button on here and assigned it to a feed. When that button is pressed, it passes a value of 1 to the feed</li></ul><ul ><li >I connected the feed to my Arduino code using Adafruit's API</li></ul><ul ><li >The API function listens for new data from the feed. I wrote a function in there that said IF the feed sends a value of 1 ----> Arduino should send power to the remote, therefore firing off the power button. It should also turn on the green LED so I see it was activated. </li></ul><h3 >IFTTT:</h3><ul ><li >I made an applet on IFTTT and connected it to Adafruit and Google Home </li></ul><ul ><li ><strong >IF</strong><span > Google home is told "Turn on the AC", </span><strong >THEN</strong><span > IFTTT will send a value of 1 to the Adafruit feed therefore triggering the Arduino</span></li></ul><ul ><li >This can be repeated for Alexa, Siri, Home Assistant, etc...</li></ul><p >The steps are outlined in this Video:</p><div class="se-component se-video-container __se__float-none" contenteditable="false" style="width: 100%;"><figure style="width: 100%; height: 56.25%; padding-bottom: 56.25%; margin: 0px;"><iframe frameborder="0" allowfullscreen="" src="https://www.youtube.com/embed/mWubqbhko5A" data-proportion="true" data-percentage="100%,56.25%" data-size="100%,56.25%" data-align="none" style="width: 100%; height: 100%;" data-index="0" data-file-size="0" data-origin="100%,56.25%"></iframe><figcaption contenteditable="true"><div>Project Video</div></figcaption></figure></div><p ></p><figure><img src=https://projects.arduinocontent.cc/023e6f29-dd37-41bf-b5ec-363985de56c0.jpg /><figcaption>Pinout reference from randomnerdtutorials.com</figcaption></figure><p ></p><figure><img src=https://projects.arduinocontent.cc/116b0dfd-e734-4bb1-88f5-83242814519e.png /><figcaption>Project Diagram</figcaption></figure><p ></p>
