IoT Edge Node of Home Assistant
This project utilizes Nordic Semiconductor's nRF52DK and STM X-NUCLEO-IKS01A3 to create a sensor-based system. Employing ZephyrRTOS and Bluetooth Low Energy (BLE), the nRF52DK gathers data from sensors like LSM6DSO (MEMS 3D accelerometer + 3D gyroscope), LIS2MDL (MEMS 3D magnetometer), LIS2DW12 (MEMS 3D accelerometer), LPS22HH (MEMS pressure sensor), HTS221 (capacitive digital relative humidity and temperature), and STTS751 (temperature). The goal is to develop a simplified system akin to Raspberry Pi Home Assistant, leveraging the Django framework. Data transfer occurs via Bluetooth GATT, where the nRF52DK acts as a BLE server reading commands from Redis messages hosted on Docker. Responses are then relayed back to the Django server via Redis pub/sub channels. Utilizing Django Channels, WebSocket messages are transmitted to the Django site router and then to the internet for further processing.
