A few libraries already exist for working with Universal Plug and Play (UPnP) devices.
This library tries to provide a minimal implementation for discovery with a small amount of code and library dependencies.
For more info on uPnP, see: http://www.upnp-hacks.org/upnp.html
Add this line to your application's Gemfile:
gem 'simple_upnp'
And then execute:
$ bundle
Or install it yourself as:
$ gem install simple_upnp
You may either:
- search for a configurable number of seconds and return all unique devices that have responded.
- attempt to find a specific device and exit early once found
The following example shows search (which can be triggered with the included rake task: "rake simple_upnp:search"):
include_location_details = true
devices = SimpleUpnp::Discovery.search()
devices.each do |device|
puts 'Device Found: '
puts device.to_json(include_location_details)
puts ''
endThe following example shows find (which can be triggered with the included rake task: "rake simple_upnp:find_hue"):
include_location_details = true
hue_device = nil
SimpleUpnp::Discovery.find do |device|
device_json = device.to_json(include_location_details)
if device_json['root']
if device_json['root']['device']
if device_json['root']['device']['friendlyName']
friendlyName = device_json['root']['device']['friendlyName']
if friendlyName =~ /Philips hue/
hue_device = device
break
end
end
end
end
end
if hue_device
puts 'Device Found: '
puts hue_device.to_json(include_location_details)
puts ''
endSearch should produce output similar to the following:
