Multimeterwire stripperI created this project for a couple of reasons; one, I got tired of trying to get the built in garage door openers in my vehicles to work with both of my garage doors. Second, was that nagging question "Did I close the garage door?". Now I can get that question answered with a couple of taps on my smart phone.  patio door repairs hampshireAlso, the device will send me an openHAB notification to my smart phone if the garage door is left in the "AJAR" or "OPEN" position for longer than 15 minutes.sliding wardrobe door brushesThe project consists of a HUZZAH, relay, power supply, resistors and LEDS.  tri fold patio doors costThe HUZZAH connects to your local WIFI and runs a small web server that responds to simple http GET/POST requests that will be sent to it via openHAB. screen door repair jacksonville beach fl

The relay works just like your existing wired garage door switch to activate the opener except for it's controlled over WIFI via the HUZZAH. The LEDs are there to provide you status information.  The red LED flashes if the garage door is not in the open or closed positions.  The yellow LED flashes constantly until connection to the WIFI is established. It will also flash briefly every time a valid request is sent to the web server.  In this writeup I will cover building and installing the garage door opener project.  I will not cover installing and configuring openHAB, there are plenty of articles on the web that cover that.  /adafruit-huzzah-esp8266-breakout/assemblySetup Arduino IDE to support the Adafruit HUZZAH.  /Build the garage door opener circuit on a PCB board. Started by hot gluing the relay down to the PCB in the upper left corner and then add the HUZZAH by soldering one or two pins to the PCB to hold it in place.Relay position on PCBRelay and HUZZAH positioning on PCBAdd the LEDs they need to placed as shown to match up with the 3D printed case design provided.

Install them so the bottom of the LED is about an 1/8 of an inch above relay.  That way they will fit neatly in the holes in the case lid.    LED locationInstall LEDs so the bottoms are 1/8 above the relayAfter the LEDs add all other components and solder them in place with the connections shown in the images. To make the circuit connections use small pieces of stripped CAT-5 cable wire. I find trying to make the solder flow from one solder point to another just leads to large blobs of solder.  I also used an old computer CD audio cable to connect the relay. Physical layout of components on PCB  Physical circuit paths on PCB Circuit paths on PCB Layout of components on PCB Before installing the device on your garage door you should get openHAB up and running. Test all the functions of the device thru openHAB before installing. NOTE: if you want openHAB to send you notifications like the one in the rules file you must use openHAB 1.8 or newer.Install the open and close contact switches.

If you have a Craftsman or Chamberlain screw drive garage door opener you can use the 3D printed mount designs provided.  I suggest using hot glue for all the glueing.  Hot glue dries fast and can easily be removed if you need to reposition the mounts or contact switches. Start by gluing one of the contact switch magnets on the the trolley. Slide both mounts onto the track from the motor end. Close the garage door and position a mount above the trolley. Glue one of the contact switches on the mount with no more than an 1/8 gap between the switch and the magnet on the trolley.  Use a multimeter to measure the resistance across the switch leads to verify that it reads closed.  Hot glue the mount in place on the rail using a small amount of glue.  It's my experience that the magnet and the switch need to be slightly offset for the switch to read closed as seen in the images. Open the garage door all the way open and repeat the process. Run wire from the contact switches to the back of the motor using cable tie mounts to keep wire from getting tangle in the trolley.

The first version of this project was built using just a ESP8266-12.  But by the time I added a buck converter, reset and flash buttons the cost was a lot more then then HUZZAH. It looks like uploading code to the feather is easier than the HUZZAH and I can use a standard USB cable to power the device.Read moreMike Mackes ContactNoah Mackes High School Student with a passion for engineering and just building stuff.
