This work extends the IKEA-Hackant project from Robin Reiter, who reverse engineered the controller board of an IKEA Bekant motorized adjustable table.

In my project i connected an ESP-12F module (ESP8266) to the Arduino, which gives us WiFi and quite some processing power to add additional IoT functions to the Bekant table.

An Alexa Skill is implemented, which when activated with a voice command, calls an AWS Lamda function which in turn sends a REST message to the AWS IoT backend. This backend then sends an MQTT message to our controller which finally moves the table.
