![]() ![]() The only exception is the most recent Security+ 2.0 systems, which come with a yellow learn button and antenna. For most garage door systems, you can simply connect the two wires from the OpenGarage controller to where you would normally insert your door button wires into. OpenGarage uses a relay to simulate door button clicks. This way the logic is reversed: if the distance reading is small, it means the door is closed, and vice versa. Instead, you can mount it to the side of the door, with the sensor facing the outside. The distance value can also tell you if your car is parked in the garage or not, which is an additional benefit that can be useful at times.įor roll-up garage doors, the ceiling mount would not work. So by checking the distance value, it can tell if the door is open or closed. When the door opens and comes up, the sensor reads the distance to the door, which is a much smaller value. When the garage door is closed, it reads the distance to the ground, or the top of your car if you’ve parked in the garage. The controller is typically mounted to the ceiling at the garage, with the distance sensor facing down. a microUSB connector and CH340G USB-serial chip.a relay (for triggering garage door actions).an ultrasonic distance sensor (HC-SR04).The built-in interface is used for local access and changing configuration/settings, while the Blynk app is used for remote monitoring and control. The controller supports a built-in web interface with embedded HTMLs, and remote access through the Blynk app. ![]() With OpenGarage, I can now check my garage door status wherever I am, open or close the door remotely, and check the record of recent events through the log and history graph. Two pictures of the circuit board are shown on the right above. I made the prototype version using a 3D printed case, and the final version using an off-the-shelf case with custom cutouts. Here are some head shots of the OpenGarage controller: Here is a video introduction that gives you a quick walk-through: If you are interested in OpenGarage, you can place your order at /cart/og. Also, the first production run has been ordered, and they should be ready to ship in 2 weeks of time. A more professional-looking site is under construction and should be ready soon. Recently as I started learning about ESP8266, I found it to be the perfect platform to help me complete this project.Ī quick note: this blog post is temporarily the main landing page of opengarage.io. Having a WiFi-based garage door opener (which I can access remotely using my mobile phone) would be super convenient. I’ve wanted to finish this project for a while, as there have been multiple occasions where I left the house in a hurry and forgot to close my garage door, or locked myself out of the house, or had to let a friend or handyman in while I was away. Today I am very excited to introduce you to OpenGarage - an open-source, universal garage door opener built using the ESP8266 WiFi chip and the Blynk app. The solution is to reflash the firmware using a microUSB cable. Reboot cycle issue: we’ve found a few reports of ‘reboot cycle’ where the controller continuously reboots.The solution is to update OpenGarage firmware to 1.0.4. Blynk connection issue: recently Blynk updated their cloud server, causing Blynk app to not be able to communicate with OpenGarage.OpenGarage Firmware 1.0.4 API document is available on Github. ![]()
