beek

Framework for domotizing houses using various raspberries pi 3

Installation guide:

1. Master Beek: Raspberry Pi 3 acting as router

Install hostapd and isc-dhcp-server via:

sudo apt-get update
sudo apt-get install hostapd isc-dhcp-server

DHCP server

Backup of the default config:

sudo cp /etc/dhcp/dhcpd.conf /etc/dhcp/dhcpd.conf.default

Edit the defult config file:

sudo nano /etc/dhcp/dhcpd.conf

Comment the following lines:

#option domain-name "example.org";
#option domain-name-servers ns1.example.org, ns2.example.org;

Un-comment this line

# If this DHCP server is the official DHCP server for the local
# network, the authoritative directive should be uncommented.
authoritative;

Scroll down at the bottom of the file (CTRL + V) and paste:

subnet 192.168.42.0 netmask 255.255.255.0 {
    range 192.168.42.10 192.168.42.50;
    option broadcast-address 192.168.42.255;
    option routers 192.168.42.1;
    default-lease-time 600;
    max-lease-time 7200;
    option domain-name "local";
    option domain-name-servers 8.8.8.8, 8.8.4.4;
}

Now, with this configuration we are assigning the subnet 192.168.42.10–50(40 devices in total) and we are configuring our WiFi local IP address to be 192.168.42.1. While we’re at it, we’re assigning Google’s public DNS: 8.8.8.8, 8.8.4.4. Next, let’s specify on what interface should the DHCP server servce DHCP requests (wlan0 in this case):

sudo nano /etc/default/isc-dhcp-server

Edit this line:

# File /etc/default/isc-dhcp-server
INTERFACES="wlan0"

Let’s setup wlan0 for static IP:

Shut it down:

sudo ifdown wlan0

Make a backup file:

sudo cp /etc/network/interfaces /etc/network/interfaces.backup

Edit the network interfaces file:

sudo nano /etc/network/interfaces

Edit accordingly to read:

source-directory /etc/network/interfaces.d
auto lo
iface lo inet loopback
iface eth0 inet dhcp
allow-hotplug wlan0
iface wlan0 inet static
  address 192.168.42.1
  netmask 255.255.255.0
  post-up iw dev $IFACE set power_save off

Close the file and assign a static IP now:

sudo ifconfig wlan0 192.168.42.1

Hostapd

Create a file and edit it:

sudo nano /etc/hostapd/hostapd.conf

Modify ssid with a name and wpa_passphrase to a password

interface=wlan0
ssid=WiPi
hw_mode=g
channel=6
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_passphrase=xyz
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP

Next, let’s configure the network address translation:

Create a backup file

sudo cp /etc/sysctl.conf /etc/sysctl.conf.backup

Edit the config file

sudo nano /etc/sysctl.conf

Add to the bottom:

net.ipv4.ip_forward=1

Activate it immediately:

sudo sh -c "echo 1 > /proc/sys/net/ipv4/ip_forward"

Modify the iptables to create a network translation between eth0 and the wifi port wlan0

sudo iptables -A FORWARD -i eth0 -o wlan0 -m state --state RELATED,ESTABLISHED -j ACCEPT
sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
sudo iptables -A FORWARD -i wlan0 -o eth0 -j ACCEPT

Make this happen on reboot by runnig

sudo sh -c "iptables-save > /etc/iptables.ipv4.nat"

And editing again

sudo nano /etc/network/interfaces

Appending at then end:

up iptables-restore < /etc/iptables.ipv4.nat

Let's clean everything:

 sudo service hostapd start
 sudo service isc-dhcp-server start

And make sure that we're up and running:

 sudo service hostapd status
 sudo service isc-dhcp-server status

Configure our daemons to start at boot time:

 sudo update-rc.d hostapd enable
 sudo update-rc.d isc-dhcp-server enable

Reboot the pi.

 sudo reboot

Copy all beek_master/beek files to /etc/beek/.

Set your daemon in your sudo crontab:

sudo crontab -l > mycron
echo "* * * * * /etc/beek/beek-daemon.sh" >> mycron
sudo crontab mycron
rm mycron

Config you modules in beek.conf

Add your smartphone's MAC address to trusted.conf

Set your control page

First install apache

sudo apt-get install apache2 -y

Copy all files in web/html under /var/www/html

Beek Music

You will need to install VLC media player to run this module.

sudo apt-get install vlc

Copy all files under beek_music/.beek in your raspberry's home/pi/.beek location.

Set a default playlist under ~/Music/default.

Now you can connect to 192.168.42.1 in your device to control your music.

Beek Heat

Copy all files under beek_heat/.beek in your raspberry's home/pi/.beek location.

Start your Sense Hat emulator or connect a real one.

Start the server running python ~/.beek/server.py

Now you can connect to 192.168.42.1 in your device to control the heat.
