    Step 1

    It’s common to talk about smart home as the tool that makes your everyday life at home easier and more comfortable, but smart home can also be a great help a lot to set your mind at ease when you’re away for a long period of time, on a vacation and possibly outside of the country. Being able to keep an eye on what’s happening in your house and be alerted when something happens is very helpful on keeping you relaxed and reassured during your off time.

    We propose you today to guide you into setting up the necessary tools and automation to have your house monitor itself for you and be remotely accessible at anytime.


    • Turn an old webcam into a smart cam that will warn you of any detected motion, take regular snapshots as well as on-demand visual reports
    • Sound sensor to detect any unusual activity in the house
    • Old smartphone used to monitor the entrance door or a sensitive room
    • Remotely control lights to make the house appear occupied
    • Trigger an alarm to warn neighbors and scare off intruders
    • Remotely control HVAC appliances to come back in a welcoming interior climate

    Most smart devices on the market offer similar features but are very costly solutions. If you’re not willing to invest in such products, or if you have already one or two of these devices but want to implement new features for cheap, this project is for you.

    You can make this project in around one hour, with a $50 budget and with no specific skills.
