[Hans Nielsen] has a couple roommates, and his garage has become a catch-all for various items. And like any good hacker’s garage, it boasts an IoT controlled garage door opener. It had a problem though, it used a Particle Photon – a popular IoT board that required internet access and a web server to operate. So [Hans] raided his roommate’s spare parts bin and set-forth to rebuild it!
One of his main goals was to make something that did not require internet access to operate. Anyone connected to the local WiFi should be able to open and close the door via a web interface, and he would give our good friend [Linus Torvalds] a call to make it happen. The key component in the build is the C.H.I.P SBC that made the news a while back for being ridiculously cheap.
Be sure to check out [Han’s] blog if you’re at all interested in working with the C.H.I.P. He does a fantastic job of documenting the ins and outs of getting a project like this working.
Internet of Things startup Garadget remotely bricked an unhappy customer’s WiFi garage door for giving a bad Amazon review and being rude to company reps. Garadget device owner [Robert Martin] found out the hard way how quickly the device can turn a door into a wall. After leaving a negative Amazon review, and starting a thread on Garadget’s support forum complaining the device didn’t work with his iPhone, Martin was banned from the forum until December 27, 2019 for his choice of words and was told his comments and bad Amazon review had convinced Garadget staff to ban his device from their servers.
The response was not what you would expect a community-funded startup. “Technically there is no bricking, though,” the rep replied. “No changes are made to the hardware or the firmware of the device, just denied use of company servers.” Tell that to [Robert] who can’t get into his garage.
This caused some discontent amoung other customers wondering if it was just a matter of time before more paying customers are subjected to this outlandish treatment. The Register asked Garadget’s founder [Denis Grisak] about the situation, his response is quoted below.
It was a Bad PR Move, Martin has now had his server connection restored, and the IOT upstart has posted a public statement on the matter.– Garadget
This whole debacle brings us to the conclusion that the IoT boom has a lot of issues ahead that need to be straightened out especially when it comes to ethics and security. It’s bad enough to have to deal with the vagaries of IoT Security and companies who shut down their products because they’re just not making enough money. Now we have to worry about using “cloud” services because the people who own the little fluffy computers could just be jerks.
It seems like every few months we cover another garage door opener, and the concept is quickly becoming the “Hello World” of DIY home automation. In this installment, reader [ray] made his own garage door opener and chose the ESP8266 as the wireless interface of choice, but spiced the application up with an ultrasonic sensor that detects whether the car is in the garage and a web app that shows history, plus integration with Blynk for remote access. For posterity, he made the project open source as well.
The video is well produced with lots of details and instructions, and the circuit board and assembly are refined and clean. It may be a “Hello World”, but it’s done right.
Some of the other garage door hacks we’ve covered in the last year include the fingerprint scanner opener, the IM-ME opener, the motion-based security opener, the cat-enabled opener, the OpenCV Pi opener, and a Bluetooth Low Energy opener.

Now here’s a really cool home hack. [Luis Rodrigues] has automated his garage door to open, simply by flashing his headlights at it.
But wait, doesn’t that mean anyone could break into his house? Nope. At first we thought he had just added some photo-sensors and a bit of computer logic in order to turn a pattern of lights into an output to open the garage, but no, it’s actually specific to his car only. Which is awesome because if anyone ever tried to copy him to break in, all they break into is a very confused state of mind.
You see how it actually works is the headlight output is connected to a control box under the hood of his car. A Moteino (RF Arduino variant) reads the input signal of the headlights flashing three times, and then communicates wirelessly to the garage door in order to open it.
But [Luis] also has a gate outside his property — so if you hold the lights on for a second, both the garage door and the external gate will open as well.
