ssh into your pi or whatever your server may be.

The first thing we are going to do is create the Fire Sensor item.

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

Then type in the comment //Fire Sensors then underneath that we are going to create the fire sensor item.

So type in String MKFireSensor1 "House [%s]" <fire> { mqtt="<[broker:MK-SmartHouse/utilities/MK-FireSensor1:state:default]" }

And press enter.

Now press control x then y and enter.

Next up is the sitemap file so we can see the status of the device.

Let's make it send a notification to the mobile devices when it detects a fire.

In ssh type in sudo nano /etc/openhab2/rules/home.rules and press enter.

At the bottom of the file type in
