If you are like [Gbola], then you have a hard time waking up during the winter months. Something about the fact that it’s still dark outside just makes it that much more difficult to get out of bed. [Gbola] decided to build his own solution to this problem, by gradually waking himself up with an electric light. He was able to do this using all off-the-shelf components and a bit of playing around with the Tasker Android application.
[Gbola] started out with a standard desk lamp. He replaced the light bulb with a larger bulb that simulates the color temperature of natural daylight. He then switched the lamp on and plugged it into a WeMo power switch module. A WeMo is a commercial product that attempts to make home automation accessible for consumers. This particular module allows [Gbola] to control the power to his desk lamp using his smart phone.
[Gbola] mentions that the official WeMo Android application is slow and includes no integration with Tasker. He instead decided to use the third-party WeMoWay application, which does include Tasker support. Tasker is a separate Android application that allows you to configure your device to perform a set task or series of tasks based on a context. For example you might turn your phone to silent mode when your GPS signal shows you are at work. WeMoWay allows [Gbola] to interact with his WeMo device based on any parameter he configures.
On top of all of that, [Gbola] also had to install three Tasker plugins. These were AutoAlarm, Taskkill, and WiFi Connect. He then got to work with Tasker. He configured a custom task to identify when the next alarm was configured on the phone. It then sets two custom variables, one for 20 minutes before the alarm (turn on the lamp) and one for 10 minutes after (turn it off).
[Gbola] then built a second task to actually control the lamp. This task first disconnects and reconnects to the WiFi network. [Gbola] found that the WeMoWay application is buggy and this “WiFi reset” helps to make it more reliable. It then kills the WeMoWay app and restarts it. Finally, it executes the command to toggle the state of the lamp. The project page has detailed instructions in case anyone wants to duplicate this. It seems like a relatively painless way to build your own solution for less than the cost of a specialized alarm clock lamp.
