使用 NodeMCU ESP8266将有线接触传感器和/或运动传感器连接到 SmartThings_Lua代码

# Update July 15, 2017 ## This project has been renamed and superseded by [Konnected Security 2.0](https://github.com/konnected-io/konnected-security) The original author (**@heythisisnate**) teamed up with SmartThings community member **@copyninja** and we created a complete re-write of this alarm system integration project that's much easier to set up and more stable. We recommend **all users** upgrade to the new version: [https://github.com/konnected-io/konnected-security](https://github.com/konnected-io/konnected-security) See the [SmartThings Community release announcement thread here](https://community.smartthings.com/t/release-konnected-security-2-0-connect-wired-alarm-system-sensors-and-siren-to-smartthings-big-update-and-new-name/92828/7) Also check out the [Konnected Security Install Guide](https://docs.konnected.io/security-alarm-system) for more detailed setup and wiring instructions. Unfortunately, since this is a re-write, there's no direct upgrade path for users of the original project to Konnected Security 2.0. You'll have to remove your devices from SmartThings and set them up again using the app. ## SmartThings Connected Wired Security System using a NodeMCU ESP8266 This project will help you connect wired contact sensors and motion sensors from an old wired home alarm system (such as Honeywell, ADT, Interlogix, etc) to Samsung SmartThings. Convert your old wired alarm system into an internet connected Smart Alarm! We use an inexpensive NodeMCU ESP82660 wifi enabled development board to connect our wired alarm system sensors to the SmartThings. There are three components to the project: 1. a SmartThings Device Handler for contact sensors and motion sensors 2. a SmartThings SmartApp that interfaces with the Wifi-connected device in your home 3. Lua code for the NodeMCU device that connects your wired system to the cloud ## Update June 17 2017 #### Release 1.6: Easy OAuth and Pre-Loaded Kits Available for Pre-order! **Easy OAuth:** Many people who contacted me for help were having trouble with the OAuth flow. In the latest [1.6 release](https://github.com/heythisisnate/nodemcu-smartthings/releases/tag/1.6) this is now much simpler! You no longer have to manually do the OAuth step. Just open your browser, copy and paste your OAuth Client ID and Secret when prompted, and the application handles the rest. **Pre-loaded Kits for Sale!** I'm working hard to make it as easy as possible for anyone to connect their wired alarm system to SmartThings, so I've decided to begin selling all-inclusive DIY kits with this software pre-loaded! With one of my DIY kits, there's no flashing or code to modify. Simply wire your sensors and alarm following the online instructions and open up your web browser to configure. ### [Now Accepting Pre-orders](https://nodemcu-smartthings.com/collections/wired-alarm-system-smartthings-connection-kits-and-accessories) for first shipment in August 2017 <img src="screenshots/complete-kit.jpg" width="252" height="189" align="right"/> #### [Wired Alarm System Complete DIY Kit](https://nodemcu-smartthings.com/collections/wired-alarm-system-smartthings-connection-kits-and-accessories/products/wired-alarm-system-complete-kit) * For connecting up to 5 sensors and one siren or alarm * Software is pre-loaded!

I'm not interested in using the outdated alarm system panel, but I wanted to connect the contact sensors in my doors and the motion sensor in my house to SmartThings. I learned about the NodeMCU ESP8266, a small, cheap, programmable development board that has WiFi built in. I set out to connect my door and motion sensors to the NodeMCU and program it to update SmartThings every time a change is detected. ### Materials 1. A NodeMCU development board. [This is the one I bought on Amazon](https://www.amazon.com/gp/product/B010O1G1ES/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B010O1G1ES&linkCode=as2&tag=heythisisnate-20&linkId=2234c680df64af67b74eb313b8ca82df) for about $8 with Prime shipping. 1. A [basic breadboard](https://www.amazon.com/gp/product/B00WZSSDCW/ref=as_li_qf_sp_asin_il_tl?ie=UTF8&tag=heythisisnate-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B00WZSSDCW&linkId=9d7c5cb3d9c1dde81a0789567f296c78) or [3-pack](https://www.amazon.com/gp/search/ref=as_li_qf_sp_sr_il_tl?ie=UTF8&tag=heythisisnate-20&keywords=B01N12ZULY&index=aps&camp=1789&creative=9325&linkCode=xm2&linkId=ea15eee83d4897e13cfab03e3ffea1b3). 1. Some [extra wires of various male/female combinations](https://www.amazon.com/gp/product/B01FSGGJLY/ref=as_li_tl?ie=UTF8&tag=heythisisnate-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B01FSGGJLY&linkId=c23cd9573b73d437a52781fee10722e6). 1. A [microUSB power supply](https://www.amazon.com/gp/product/B00GF9T3I0/ref=as_li_qf_sp_asin_il_tl?ie=UTF8&tag=heythisisnate-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B00GF9T3I0&linkId=72fc777b3abc63d2c2b86d1ff1343e18) or try one of these [other ways to power the device](http://henrysbench.capnfatz.com/henrys-bench/arduino-projects-tips-and-more/powering-the-esp-12e-nodemcu-development-board/) 1. To connect your alarm siren or strobe light, you'll need a relay that the board can switch with a 3.3V signal. [These work well](http://amzn.to/2olmuNb) and are only a few dollars [each](http://amzn.to/2obFako) (ship from China). _Update:_ Later on I saw [this NodeMCU board with a base](https://www.amazon.com/gp/product/B01MDTKAR2/ref=as_li_qf_sp_asin_il_tl?ie=UTF8&tag=heythisisnate-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B01MDTKAR2&linkId=f5b8649950c46c0644e88dfbace7567d) that looks like it eliminates the need for a breadboard. And [this kit](https://www.amazon.com/gp/product/B01N3KO7QV/ref=as_li_qf_sp_asin_il_tl?ie=UTF8&tag=heythisisnate-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B01N3KO7QV&linkId=d4335e6ef6331d73be4fa83bf3cfc338) also includes 40 jumper cables making it an attractive all-in-one starter set. _Update 2:_ One user reported that he had success with [this board](https://www.amazon.com/gp/product/B01N3P763C/ref=as_li_qf_sp_asin_il_tl?ie=UTF8&tag=heythisisnate-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B01N3P763C&linkId=f546e4e49606dfb8ec7bd89b0cadfeb4) which has 7 GPIO pins available for connecting sensors. With the board I bought and linked above, I could only get 4 or 5 pins working reliably. This may be a good option if you have more sensors and don't want to set up multiple devices. ### Annotated Photo  ## Updates ### v1.6 / 2017-06-17 _Feature:_ Easy OAuth.
