Playing Yeelight with Python

Recently I've been playing a Yeelight Smart LED Bulb. It'd be a good starting of learning home automation, as such smart LED Bulbs do not depend on any modification of your home electricity system. This yeelight bulb is already bundled with the WIFI chip so that you can configure it using its official app (both Android and iOS are available)

Using the official app is straight forward, then I wondered can I play it 'harder'. Then I searched and found some interest use cases:

  1. Controlling yeelight by Python
  2. Controlling yeelight by Siri (wow!)
  3. Controlling yeelight by Home-Assistant
In fact there should be more cases, including Amazon Alexa or Google Home, but I do have these products and the setup will be very similar to 2. and 3, that I will explain it in another post later. Right now I am going to share how to play the yeelight with python.

First, you need the official app to enable developer mode. Then just use python yeelight package and you are good to go!

import yeelight
yeelight_ip='' # your yeelight bulb IP
light = yeelight.Bulb(yeelight_ip, effect='smooth')

# Set it to white
# Set the brightness

Not very difficult right? If you have a raspberry Pi you can set some cronjobs in order to turn the light on in the morning as a silent  alarm clock, or place the bulb in your kid's bedroom, then change the brightness from 100% to 1% (then off, of course) in one hour.

If you think it's too dummy to control such a bulb, I agree. That's why there will be some more elegant solutions. Next time I'll show how I setup a virtual HomeKit and ask Siri to control the bulb.
