JeeLight is a fantastic piece of software that allows you to operate Yeelight devices from a PC. It was created since there was only one other similar app for DMV Practice Test PC that could only handle one Yeelight at a time - JeeLight can control up to eight at once and has a ton of additional options for the user to play with.

F.lux is a utility that darkens your display in the evening and at night to reduce eye strain and promote more natural sleep patterns. You can use this tool to create a retro bowl light scene using Yeelight smart lighting that corresponds to the temperature of your f.lux display. Supports any number of lamps at the same time.
