This repository contains the Microservices-based backend and the Web app for a smart thermostat. The project consists of a microcontroller talking to an IoT Hub via MQTT (VerneMQ), sending temperature and humidity data. The IoT Hub publishes the received data (events) to Kafka and the API Gateway subscribes to the broker and delivers the measurements to the web application via WebSocket. A chart is displayed to the user showing the measurements of the microcontroller in real-time. It also displays the data of a tilt sensor and a button which can toggle a fan (connected to the microcontroller) on/off by sending a command to the device. The communication basically looks like the following:
Web App <-via WebSocket-> API Gateway <-via Kafka-> IoT Hub <-via VerneMQ-> Microcontroller
The Backend folder contains the API Gateway and the IoT Hub as well as an application used for testing the MQTT communication and a docker-compose.yml file for spinning up the necessary infrastructure for a development environment.
The Web-App folder contains the Angular SPA.
If you have any questions about the applications, you'd like to know how to run them/interact with them or you wanna see the C code and the microcontroller (ATmega328 + ESP8266) used then feel free to contact me via mmaresch.com.
