These lights don't need a controller, have polished iOS and Android Apps, a programming API https://www.yeelight.com/en_US/developer, and integration with Domoticz https://www.domoticz.com/ home automation software. (I helped with the the integration and think these lights are currently the best option considering price/performance).

Repost after the last deal for $14.88, now $10.29 https://www.ozbargain.com.au/node/280195
Also Smart socket/plug for $13.13 http://aud.dx.com/product/original-xiaomi-zigbee-version-mi-..., I think this needs the Xiaomi Gateway though, which is worth getting imho.
