YeelightClient

Official implementation of Yeelight Operation Spec

https://www.yeelight.com/en_US/developer

Add this line to your application's Gemfile:

gem 'yeelight-client'

And then execute:

$ bundle

Or install it yourself as:

$ gem install yeelight-client

This gem split into two parts. The first is to how to discover all Yeelight lights in your local network.

results = YeelightClient::Broadcast.new(logger: Logger.new(STDOUT)).discover
results.first.addr

You will see something like this if your have many lights:

I, [2019-11-02T23:42:56.142927 #3071]  INFO -- : Receive #<UDPSocket:fd 9, AF_INET, 0.0.0.0, 56343>
I, [2019-11-02T23:42:56.143275 #3071]  INFO -- : Receive #<UDPSocket:fd 9, AF_INET, 0.0.0.0, 56343>

Get an addr from results:

irb(main):002:0> results.first.addr
=> #<Addrinfo: 192.168.31.64:55443 TCP>
irb(main):003:0> addr.ip_address
=> "192.168.31.16"
irb(main):004:0> addr.ip_port
=> 55443

For now you have every Yeelight host and port. We have to go next part of this gem Yeelight Client.

Initialize client with received addr or with host and port

client = YeelightClient.new(addrs: addr, logger: Logger.new(STDOUT))

client = YeelightClient.new(capabilities: { host: "192.168.31.16", port: 55443 }, logger: Logger.new(STDOUT))

Client supports only two methods: set_bright and set_rgb

client.set_bright(100)
client.set_rgb(0xff0000)

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
