Hey guys Matt here from MKSmartHouse.com and in this video I am going to show you how to

setup the software for the door sensor using a Windows Computer.

So in the last video we left off with the door sensor being fully built so all it needs

is firmware and to be connected to the home automation server.

I recommend having my website open up so that way you have all the steps and commands ready,

and so you do not have to type in everything you can just copy and paste.

I know this is the software video but, there are some hardware things that we need besides

We are going to need an arduino of some kind preferably a UNO or a MEGA equivalent with

its usb cable of course and male to male dupont jumper cables.

Links to these items will be in the description or on the website.

The first thing we are going to do is grab the arduino and put a jumper cable from RES

Then grab the door sensor and connect all the pins to their corresponding spots so,

TX to TX, RX to RX, GND to GND, and 5V to 5V.

Before we continue, check to make sure the 2 pin jumper is above PGM.

Next we are going to go to the computer and go to the Arduino website https://www.arduino.cc/en/Main/Software

scroll down to download the Arduino IDE, and click Windows Installer, then press download.

Next, go to File Explorer and your downloads folder.

Double click on the arduino installer and click yes in the pop up.

It will ask you to install device software, click install for all the pop ups.

Find the arduino icon on your desktop and double click it.

Great we installed the arduino IDE, so now plug in your arduino.

To confirm your arduino is connected in the top bar go to Tools and if you hover over

Port: you should see COM and then a number if you can then select it.

(If you have a couple COM’s then unplug the arduino and see which com disapeared,

that is the arduino) Now we are going to add the ESP8266 boards so go to Arduino, then

preferences and in Additional Boards Manager URLs: type in http://arduino.esp8266.com/stable/package_esp8266com_index.json

Then hover over board and to the right click Boards Manager.

It should be the first one and it should say esp8266 by esp8266 Community.

Once it is installed press the close button.

Now, go back to Tools, hover over board and go to the right and scroll down to and click

Next we are going to add the MQTT Library, so go to sketch and in the drop down hover

over Include Library and in the right click on Manage Libraries.

Scroll through the list to find the one that Says MQTT by Joel Gaehwiler, click on it and

Close out of arduino and now all we have to do is grab the code so we are going to head

over to my site, the link is in the description to the exact page and press the download MK-DoorSensor

(Insert the rest of what goes here in terms of downloading) Then go to file explorer and

then downloads folder and double click on MK-DoorSensor.ino.

A pop up will come up asking if you want to put it in a folder, click OK.

It should bring up the code for the door sensor, and there are only a few things we have to

The first thing is the wifi settings which are the ssid and password so change those

Please keep in mind that the esp8266 only works on 2.4ghz so type in your 2.4ghz wifi

Also when adding the information only change what is inside the quotation marks.

Next set of parameters are the Web Updater settings.

The devices I designed are great because I implemented a web user interface for each

individual device so that way if you ever have to flash new firmware you just go to

The web address information is found at that top of the code in the giant comment block.

The first parameter is the hostname of the device, usually I only change the last digit

but since this is the first door sensor I will keep it as it is.

Next is the update path and personally I don’t change that.

After that is the web user interface username and password, these are the credentials you

use to access the webpage because each device is protected.

The first one is the outTopic and this is the topic for which the device sends commands

The next one is the MQTT Server Ip address and this is simply the IP address of your

The last one is the Unique device ID and this simple differentiates each device on the MQTT

side, I usually just change the last digit for every single device.

That is it the code is ready to be flashed.

So go to tools and make sure the Board: is Generic ESP8266 Module and the port is COMX.

Once those are good press the upload button, it is the one with an arrow pointing to the

When it is uploading you should see dots moving at the bottom and some percents.

After it is done uploading you should see it say 100% and Done uploading.

To confirm that it flashed correctly and is working you can fire up MQTT.fx, connect to

the server and in the subscribe section type in # and press subscribe.

Now if you separate and bring together the two contacts of the door sensor you should

see it either say OPEN or CLOSED depending on its current status.

If you do not have MQTT.fx then check out my Home Automation Server Setup Guide.

Now that we know it works let's close up the device and get it ready for use with the Automation

First unplug the dupont wires in between the arduino and the device.

Then take the 2 pin jumper and move it over so it is above RUN.

After that take the lid to the device and put it on.

Now the device is complete and just needs to be added to OpenHAB.

So ssh into your pi or whatever your server may be.

The first thing we are going to do is create the door sensor item.

So type in sudo nano /etc/openhab2/items/home.items and press enter, you may need to type in admin
