RFLED Server Python

Small python app to run UDP servers emulating LimitlessLED / Milight / Applamp WiFi Bridge 4.0 units. Originally forked from riptidewave93/RFLED-Server to add support for multiple milight bridges. As the original project has been ported to Go and this fork was in the end a nearly complete reimplementation anyway, both projects drifted strongly apart. As a consequence, this fork has been detached and is now offered as a separate project.

Hardware setup

See http://servernetworktech.com/2014/09/limitlessled-wifi-bridge-4-0-conversion-raspberry-pi/

Install

1. Install python3 and python3-yaml on your machine. On new linux distributions, python3-serial is also needed.
2. Take the config.example.yaml and configure it according to your needs. Rename it to config.yml.
3. Put config.yaml to the source folder or elsewhere (in case of the latter, set the environment variable RFLED_CONFIG_PATH to the path of config.yaml)

Running

Start main.py, e.g. with python3 main.py.

Support for multiple milight bridges

1. Make sure the hardware device has multiple UART interfaces and connect the milight bridges to them (I tested it with CP2104 USB-to-Serial Adapter Carrier on the Raspberry Pi 2 -> https://www.pololu.com/product/1308)
2. For each additional milight bridge, add a virtual interface with it's own IP and MAC address. Please consider that DHCP probably won't work with these virtual interfaces, so you have to assign static IPs to them. Make sure that iproute2 is installed.

Method 1: You can create virtual interfaces by adding the following lines to /etc/network/interfaces:

auto vlan.milight1
iface vlan.milight1 inet static
   address 192.168.0.52
   netmask 255.255.255.0
   gateway 192.168.0.1
   pre-up ip link add link eth0 vlan.milight1 address 00:11:22:33:44:55 type macvlan mode bridge
   post-down ip link delete dev vlan.milight1

Method 2: On newer operating systems (like Debian Jessie) you could also use systemd-networkd to configure your VLAN. Do it like that:

• Create /etc/systemd/network/eth0.milight1.netdev

[NetDev]
Name=eth0.milight1
Kind=macvlan
MACAddress=00:11:22:33:44:55

[MACVLAN]
Mode=bridge

• Create /etc/systemd/network/eth0.milight1.network

[Match]
Name=eth0.milight1

[Network]
IPForward=yes
Address=192.168.0.52
Gateway=192.168.0.1

• Create /etc/systemd/network/eth0.network

[Match]
Name=eth0

[Network]
MACVLAN=eth0.milight1

3. Reboot the device
4. Adjust the variables within the scripts according to your own configuration
