Home Automation

In this Instructable I will be using a couple of Particle Electrons, Raspberry Pi3 as my base electronics.I will add a Basic BOM(Bill of Materials).I am also designing a DIY Security system into this.. as well as simple Heating Control sketch

With this system you will be able to go on Holidays and rest easy that your home is safe and secure.(with no Leaks ) and you will be notified when there is trouble.

In this instructable I will demonstrate how to design and build your own Home Automation systems that includes sensors , Relays , Flood sensors ,Water shut offs , Water Flow sensor, and temperature sensors for every room.

The remote Water Flow meter Board that sits on your main intake pipe after the Flow meter and shutoff.I have included a gerber file for this Board.It requires power to operate. either a battery setup can be included in it or regular power from the USB.. I will be using the USB power block as it's easier to design into the Board and Junction Box.

The Remote Water leak Board this sits on the floor of your water closet or mechanical room or even in the bathroom where you might have a leaky toilet..A gerber file is attached

The Remote Relay Board this mounts near the Solenoid shutoff your water or mechanical room or even in the bathroom where you might have a leaky toilet..A gerber file is attached

You might have noticed the sensor boards are all exactly the same in size.I did that on purpose so as to only have 1 box type for all sensors

For the Main Control Board that sits in the Control Cabinet. I have included a gerber File for the enthusiast that doesn’t want to go through the hassle of doing a total design work up.
I have 3 relays designed into the Board.
1-can be used for an alarm Bell
1-can be used for turning on and off the solenoid
1-can be used for turning heating or Air conditioning on and off.
The Raspberry Pi Zero can be soldered into place in the spots provided to get power from the Board

I designed this board for my solar project but it works for just about any Design Challenge you may have ..I'll include a gerber file for this board as it is awesome ..it has dual inputs for voltage..DC and AC up to 30 Volts..Two relays and all inputs are useable ..

The following are links to Products and programs I used to Design My Boards and have them made.

Soldering the Board.…work your way from the inside to the outside of the Board. briefly touching the pins to be soldered. Don't linger too long as you may melt the pieces above you on the other side of the Board. You just want to wait long enough for the solder to liquefy that you are touching to the iron and the piece pat the same time. If you are not sure what you are doing practice on a blank board with some cheap resistors till your comfortable

So now after you've ordered all your Parts and they Have come in ..And you've soldered them.
Let's put them into their Appropriate boxes

Your Going to need some basic tools for this ..A plumbers Adjustable jaw wrench, A bucket ,Some Teflon Tape ,Basic hand eye coordination ..I've included a pezeo sensor to detect when my water Pressure tank engages telling me if the is water flowing (water flowing drops the pressure of the tank then activates the pump(Well system)

The Water Leak box is a simple sensor setup using Small 10/32 screws and nuts attached to the Particles +3.3 volt output on the sensor board and the D1 input ..Basic theory ..Water is conductive ..Water will breach the contacts ..Send 3.3 volts to the Particle input waking up the Particle which is in a deep sleep ..It'll send a text and an alert to your phone ..You have to send a message back to the particle using a function ..just type in a 1 and send to put it back to sleep..

Test every device before you power it up with the particle in it

I decided to use a Pezio sensor to sense Flow and actuation of my Pressure switch as I have a well system and wanted to know when the switch was activated.

Programming is relatively easy using the Particle and there is no weird code to fight with ..You will have to use the libraries button in the ide to get everything to work. But there are excellent tutorials around for this.

The Code For Openhab 1.8 for your Raspberry Pi is in the text files above)

A great Tutorial for installing and using openHab is above as well

I decided to use Node_Red as an intermediary between the Particles and the Openhab MQTT protocols..I found it was more stable and didn't need as much babysitting .It come standard in the Raspberry Pi as a program so now downloading of the Node red is required but you need to install the Particle nodes which we will go through here.

For my notification Services I used Twillio..It messages me via SMS when there is an alarm or trouble in my house.(Water leaks , Cold temperatures, Fire or Smoke Alarms, Water flowing for no reason).

A good tutorial is available on the Particle Community Website for using Twillio and on the Twillio website. The Web hooks for both are attached.
