Smarthome Buildout

Building components for a smarthome installation

Similar projects worth following

Building a framework for smarthome systems using already existing libraries. Attempting to make it modular and standalone, not relying on any existing networks.

Also plan to build certain components for my own house, including:

-Automatic garage door opener

-Solar/fireplace heating system controller

    -setup raspberry pi with Jessie

    -installed mosquitto on raspberry pi

    sudo apt-key add mosquitto-repo.gpg.key
    rm mosquitto-repo.gpg.key
    cd /etc/apt/sources.list.d/
    sudo wget
    sudo apt-get update
    sudo apt-get install mosquitto mosquitto-clients

    -setup esp8266 using an FTDI serial USB adapter set to 3.3V:

    -Use a 3.3V regulator or a 3.3V supply for the ESP itself, not from USB (it can sink a lot of current)

    -Vcc => 3.3V

    -EN => Vcc

    -GPIO15 => GND

    -GPIO2 => Vcc via resistor (I used 10k)

    -GPIO0 => GND for flashing, then moved to Vcc for runtime

    -Rx => FTDI Tx

    -Tx => FTDI Rx

    -FTDI GND => GND

    -use esptool to flash NodeMCU float (dht,file,gpio,mqtt,net,node,tmr,uart,wifi) --port /dev/ttyUSB0 --baud 57600 write_flash 0x00000 firmware.bin

    -move GPIO0 to Vcc

    screen /dev/ttyUSB0 9600

    -setup raspberry pi 3 as wifi access point (no NAT):

    -adafruit article below

    -changed hostname


    -hostapd (device is nl80211)

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


    # Sample configuration file for ISC dhcpd for Debian
    # The ddns-updates-style parameter controls whether or not the server will
    # attempt to do a DNS update when a lease is confirmed. We default to the
    # behavior of the version 2 packages ('none', since DHCP v2 didn't
    # have support for DDNS.)

    # If this DHCP server is the official DHCP server for the local

    # This declaration allows BOOTP clients to get dynamic addresses,
    # which we don't really recommend.

    #  max-lease-time 7200;
    # Hosts which require special configuration options can be listed in
    # host statements.   If no address is specified, the address will be
    # allocated dynamically (if possible), but the host-specific information
    # will still come from the host declaration.
    #host passacaglia {
    #  hardware ethernet 0:0:c0:5d:bd:95;
    #  filename "vmunix.passacaglia";
    #  server-name "";
    # Fixed IP addresses can also be specified for hosts.   These addresses
    # should not also be listed as being available for dynamic assignment.
    # Hosts for which fixed IP addresses have been specified can boot using
    # BOOTP or DHCP.   Hosts for which no fixed address is specified can only
    # be booted with DHCP, unless there is an address range on the subnet
    # to which a BOOTP client is connected which has the dynamic-bootp flag
    # set.
    #host fantasia {
    #  hardware ethernet 08:00:07:26:c0:a5;
    #  fixed-address;
    # You can declare a class of clients and then do address...
