This project is designed for DIY home security. This project is based off the Konnected project. Konnected brings new life to homeowners that have pre-wired motion sensors from ADT and other companies. By giving it an update with new technology while not having a monthly fee. I encourage you to check out https://konnected.io if you want to know more.

I am a big user of the Samsung Smartthings platform and this project was design for that. One problem I had out of the gate was my house was not pre-wired. I was tempted to wire my house but that's too much work. So I designed a 3D printed case to hold the motion sensor and an ESP-8266 that was flashed with Konnected for around 8 dollars. Before we get started yes I know I could of bought a GE Z-Wave Plus Wireless Smart Sensor; but it's fun to make products, learn something new, and save a little money. I am not including the Smartthings hub in the price. I expect you to have that already setup.

Step 1: Hardware

I DO NOT endorse, represent, or receive anything at all for the examples below.

Smartthings hub https://www.amazon.com/Samsung-SmartThings-Smart-...

ESP - 8266 https://www.amazon.com/gp/product/B07CB4P2XY/ref=...

DIY PIR sensor https://www.amazon.com/gp/product/B012ZZ4LPM/ref=...

3D Printer ( If you don't have one, there are sites online that will print at a cost.) https://www.makeuseof.com/tag/best-sites-order-3d..

Wire https://www.amazon.com/Multicolored-Breadboard-Du... (any wire should work)
Micro USB charger and power brick https://www.amazon.com/Samsung-Galaxy-Charger-Act...

Step 2: Files and Software to Download

Programs used are for windows computers.

NODEMCU Firmware Programmer https://github.com/nodemcu/nodemcu-flasher

ESPlorer - This will be used to flash the lua files https://esp8266.ru/esplorer/

Konnected software and original guide. https://github.com/konnected-io/konnected-securit...

3D printed case https://www.thingiverse.com/thing:3090238

Step 3: Software Setup / Flashing

Flashing the firmware.

Plug in the ESP 8266 into your computer.

Open the nodemcu-flasher-master folder (which is in your downloads folder)

Select win 32 or win 64 ( depending on your computer)

Open the release folder and double click the ESP8266Flasher.exe

NodeMcu firmware programmer

In the operations tab verify the com port is correct.

Select the Config tab

Click the first gear icon

File explorer should of opened. Locate the konnected-firmware-X-X-X.bin file. (downloads- konnected security master -firmware)

Select the operations tab.

Click flash. The progress will be displayed near the bottom.

Wait till the flash is done before you continue.

ESPlorer -Installing the lua files.

Open the ESPlorer program

Verify the drop down box next to donate is set to 115200 -click open (it will change to close) -click the RTS button a few times till you see (Konnected Firmware)

Click upload near the bottom

File explorer will open. Locate the src folder (within the konnected security mater folder ) Press control A to select all.

Connecting to Wifi and setting up Smartthings.

I followed the instructions on the konnected website to setup Wifi and Smartthings https://docs.konnected.io/security-alarm-system/

Step 4: Wiring

Using the wire in the description or any you might have laying around.

Connecting
- Ground from the PIR to any GND on the ESP 8266
- Output from the PIR to pin D1 on the ESP 8266
- 5 v pin to the 3.3v on the ESP 8266 ( yes this will work)

Power

Plug the ESP 8266 into Power, wait a couple minutes.

test it by moving in front of the sensor.

If everything worked, gently slide the electronics into the 3D printed case.
