I'm not much for Karma, if you want to copy all this into a better post with pictures feel free.Step 1. buy a Wemos D1 mini and a relay board:http://ift.tt/2rQyhEO (you can get knock offs for cheaper, but I like to support the "official wemos store" because I like their product.)Step 2. wait 2 weeks for delivery.Step 3: Solder the pins, stack and, use a old phone micro USB charger for power. I also suggest putting a capacitor across the 5v and ground if you have stability issues a 470uf should be more than enough.Step 4: Your door opener button generally has a pair of wires coming out of it. Let's say the first wire is called "white" and the other one is called "white/black". Cut the wires, strip all 4 ends. Put the two "white" wires under the COM terminal on the relay. Put the two "white/black" wires under the "NO" terminal of the relay.Step 5. Install the arduino IDE and the esp8266 boards. Here's some instructions on how to do that:http://ift.tt/2t9HVWP 6. download my code http://ift.tt/2t6487V edit the SSID and password (and put it on your ESP. you may need some extra libraries.)Step 7. Find this ESP on your network, that's the hard part. The code does MDNS if that helps you, or check your DHCP server for the newest lease, or set a static IP in the code and re-upload (enable the "WiFi.config(ip, dns, gateway, subnet); " line 176)Step 8. Control your garage door from the new website garagedoor.local (if your mdns is working)Shazaam? There's probably a lot that I missed. Ask some questions.Also my code does a lot more than just control the garage door. You can put a light sensor on A0 and if you left the garage lights on it'll email you. (provided you enabled the email configs) You can put a NC reed sensor on D5 and it'll tell if the door is properly closed. You can put an ultrasonic sensor on D2 and configure it to see if the door is fully opened or if car is in the bay. There's a temp sensor option. I also have a AC unit in my garage, and the code can turn on the AC and set the temps.disclaimer The code is not warrantied nor written well. via /r/DIY http://ift.tt/2saKMtZ
