WiFi Outlet Raspberry Pi

This project is a breakdown version of my previous project here >>>

AND MY NEW PROJECT HERE! >>>>>>

I then wanted just to control and outlet for security purpose. ONLY nothing else.

So I came up with this! As you can see from the video it functions very easy and fast! In an instant!

Also with a ton of bells & whistles!

Raspberry Pi Zero W or Zero 2W & memory card 8-32GB Anything above will NOT work.

Any 5V Relay from scrap parts with NPN transistor and resistor. [x2 EVERYTHING]

Outlet Power Socket (snap in type, square) [x2]

5V 1A USB type power supply (picture in file)

External Antenna

(U.FL/IPX to RP-SMA Female Antenna wire, antenna)

U.FL IPX RF SMD SMT Solder PCB Mount Socket Jack Female Connector

CPU Heatsink (I cut and made one from scrap so that it was bigger fins)

NEON light and resistor [x2]

120VAC OUTLET PRONGS (came from scrap timer outlet)

Various wire, solder, liquid tape, hardware screws, super glue

3D printer and filament

The Pi is mounted in place with screws.

Thermal compound on heatsink and apply to chip. Don't Forget! It does get hot inside there~!

The relays are wired to Pins: 29, 31.

NEON lights are directly on the outlets.

The transistors are hot glued in place over the relays.

Run Power Supply (+) over to the relays direct. And the (-) comes from the transistors. Other end transistor goes to power supply (-) Then off the resistor you goto the pi data pins.

***PLEASE NOTE*** This relay setup runs on getting a "HIGH" while relay module runs on "LOW". So this had to be changed from my original code in MASTER PROJECT using a module. So if you decide on a module you need to change according in code. Else it will be backwards. My original code would work for module but you have to remove all extra's... Posted above.

electrical tape over the 5V power supply and glued in corner.

EXTERNAL ANTENNA EXTREMELY HARD! (youtube search)

Hopefully you get the antenna on and your good to go.

The Outlet prongs can be cut from an existing gadget? You want these close and not long so I printed out this part to hold them in place while I use a cut-off wheel.

Outlet prongs are UV super glued in place. I use another outlet on the other end to hold the prongs in place at other end all the way in. So ensure a proper connection. Then you can remove the extra outlet to see the prongs in place. You can add more glue on this side also. There is plenty of room for everything inside the box just keep wires tight! Also as you can see from picture every connection is liquid taped up for insulation and no short could happen.

Download and burn image to micro sd card

Go through settings and enable Remote GPIO

sudo raspi-config

Personal settings

sudo nano /boot/config.txt

add to bottom

avoid_warnings=1

Save and Exit. Next we change settings at startup

sudo nano /etc/xdg/lxsession/LXDE-pi/autostart

add these lines

@xset s off

@xset s noblank

@xset -dpms

(comment out screensaver with # like # @xscreensaver)

Save and Exit. Next we can set static IP

sudo nano /etc/dhcpcd.conf

Goto Bottom and add

interface wlan0

static ip_address=192.168.2.190/24

static routers=192.168.2.1

static domain_name_servers=192.168.2.1

save and exit. Next Wifi Settings

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev

update_config=1

country=us

network={

    ssid=""

    psk=""

    key_mgmt=WPA-PSK

}

Save and Exit. Now we'll Reboot for settings to take efect.

sudo reboot

sudo apt-get update

sudo apt-get full-upgrade

sudo apt-get -y dist-upgrade

Now Install Python

sudo apt install python

sudo apt install python3 idle3

To get sensor working.

sudo apt-get install python-setuptools

git clone https://github.com/adafruit/Adafruit_Python_DHT.git

cd Adafruit_Python_DHT

sudo apt-get install build-essential python-dev

sudo python setup.py install

Next we'll do Apache webserver

sudo apt install apache2 -y

Next we need permission for ftp to transfer files

cd /

cd /var/www

sudo chown pi: html

Next we change the port # of the pi

cd html

sudo nano /etc/apache2/ports.conf

change "Listen 80" to Listen 8030 Save and Exit

Now install PhP

sudo apt install php

Set permissions on ppi for browser access

sudo visudo

add the following lines at the bottom

www-data ALL=(ALL)NOPASSWD:ALL

www-data ALL=/sbin/reboot

www-data ALL=NOPASSWD:/sbin/reboot

www-data ALL=/sbin/shutdown

www-data ALL=NOPASSWD:/sbin/shutdown

www-data ALL=/sbin/sysctl

www-data ALL=NOPASSWD:/sbinsysctl

Save and Exit. 

cd ..

In the "www" folder run command

sudo chwon -R www-data:www-data /var/www

Next WE NEED Wiring Pi ABSOLUTE MUST!

cd ~

In "home/pi" folder

sudo git clone https://github.com/WiringPi/WiringPi

cd WiringPi

sudo ./build

Now you can read GPIO pins

gpio readall

Now you should be all setup that you can put the ip address and port that we had assigned in your web browser in view what we have!. Currently there should be some sort of basic index.html page there. Finally here is the link you NEED to download and unzip to replace in the "html" folder. I used filezilla to ftp to the pi and transfer the files. [/var/www/html/] If doesn't work change file permissions. There are many ways you can do this but I just do this in FTP and do all the files in folder to 777. Click link for code package

I can say there is a "hidden feature" in IE browser! via pc. Then you can use any browser on ANY device to view! These lovely buttons love to change color! Just like anything else if you want to access this outside your network port forward on router! Yes tested and WORKS! ***PLEASE NOTE***(Your IP and port may differ? Just change in the files.)

 http://IPADDRESS:PORT/index.html

Then if you have port forward that port the IP becomes the IP of your location NOT the pi!!!

If you are moving to a different location or gifting to a friend or family. These are the things you need to check and change. Everything you need to connect to network

SSID PASSWRORD IP ADDRESS RANGE

sudo nano /etc/dhcpcd.conf

interface wlan0

static ip_address=192.168.2.190/24

static routers=192.168.2.1

static domain_name_servers=192.168.2.1

save and exit. Next Wifi Settings

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev

update_config=1

country=us

network={

    ssid=""

    psk=""

    key_mgmt=WPA-PSK

}

Save and Exit. Now we'll Reboot for settings to take efect.

sudo reboot

That is all the changes you need to make.

ENJOY!

The price will vary with the purchase of the Pi Zero. For a $5 originally priced board to the current price is $60 for a Zero 2W. This is a fun project I really love! You can now remotely control anything you want from anywhere in the world you want! From practical jokes to Christmas or Halloween! or Security Deterrent. Or if you want just a fan and a light in your bedroom. ENJOY!

TESTED IN WISCONSIN WINTER INSIDE GARAGE SURVIVED WONDERFUL!!! (YEARS)

ALSO NOTE IF IN GARAGE TRY TO AIR OUT DURING SUMMER THE RAFTERS CAN GET TO BE 145F.

I WAS WORRIED BUT IT DID SURVIVE.
