Futronix Lighting (London, UK)

R&D for IoT Integration

2017-present

Client provides home lighting automation systems, solutions and applications. Worked remotely from Chiang Mai, TH.

Platforms: AWS IoT, ESP8266, Arduino IDE, Amazon Alexa, MQTT, WebSockets

Languages: Embedded C/C++

Final goal of the application is to bring the company’s existing lighting/dimming system into the world of IoT/SmartHome by connecting it to voice activation using an Amazon Alexa device (Echo, Dot, etc.) I have programmed the ESP8266 chip on the Arduino IDE, connected it on one end to Amazon’s IoT cloud, and on the other end to the existing lighting chips via RS485 and IR signals. Since reliable and well-tested TLSv1.2 libraries do not yet exist for ESP8266, securing the communication with AWS is a special challenge.
