This is an applet for Squeezeplay devices (e.g. controllers and radios), part of the Squeezebox/SqueezeOS family of devices.

It shows how you can write a a bit of Lua to consume and display realtime-ish data from a JSON endpoint. With nice icons.

On the server side, local transport websites are scraped for departure info, which is served as JSON. The device requests this JSON when the menu item is selected and shows the departure info. Simples.

Requirements

You must enable remote login on the Squeezeplay device. Make a note of the IP address and the password

Install

git clone https://github.com/textgoeshere/mulberry-squeezeplay-client.git

# scp the applet to the device (you can use IP or hostname here)
rake applet:install device=HOSTNAME_OF_SQUEEZEPLAY_DEVICE server=HOSTNAME_OF_SERVER

Install the server-side app at https://github.com/textgoeshere/mulberry-server.

Now restart (power cycle) the Squeezeplay device.

You should see a menu item "Live Travel Item". Click through to see a list of travel services and departure times.

Development

First build SqueezeOS.

Then, in the mulberry-squeezeplay-client directory:

rake applet:dev:ln squeezeplay_path=$YOUR_PATH_TO_SQUEEZEPLAY

This symlinks the applet from mulberry into the Squeezeplay applet directory. The applet will then be loaded when Squeezeplay is restarted.

$YOUR_PATH_SQUEEZEPLAY must be the path to the build directory (where Make output), not the source.

You have to restart Squeezeplay every time you make a change to the Lua source.
