I am curious about something here. A garage door does not send out any signals that indicate whether the door is open or closed. A transmitter just sends an on command, and the opener determines the direction of the motor in one of a couple of different ways, depending on the design.
So how does the app on your phone know whether the door is open or closed?
Being a tech geek, I love little projects like this, sometimes just to learn and see if my ideas work. From that standpoint, I applaud your creativity.
But being a knowledgeable tech geek also makes me avoid IoT devices like the plague, simply because the security is so poor on almost all of them. (It is often nonexistent) Knowledgeable computer guys will not go anywhere near them. I will never hook up any smart devices like light bulbs, thermostats, or devices like Alexa to my network, because they all have to connect to remote servers over the Internet, making them extremely vulnerable hacking points into a home’s private network. It’s like leaving the door to your house open. There are some really cool and tempting IoT devices on the market, but it just isn’t worth the risk. The only system I would ever use is one that operates 100% isolated on my local network, and never phones home.
