I recently stumbled upon an innovative solution to repurpose an old Xiaomi Android phone into a PostgreSQL server for my Home Assistant setup. After struggling with the complexity of setting up Home Assistant Core directly on the device, I decided to explore alternative approaches.
The process involved installing LineageOS and Termux, followed by setting up PostgreSQL. The results were astonishing—queries that previously took over 20 seconds on my Synology NAS now execute in less than a second! This upgrade has significantly improved the performance of my home automation system, especially with the UI and graph rendering.
For those interested, the setup guide is straightforward: install PostgreSQL using Termux, configure remote access, and ensure the necessary dependencies are in place. Additionally, I utilized the NMIG tool to migrate data from MariaDB to PostgreSQL seamlessly.
This project not only breathed new life into an old device but also enhanced the efficiency of my entire home automation ecosystem. It’s a testament to the creativity and problem-solving within the Home Assistant community. If you’re looking to optimize your setup or repurpose old hardware, I highly recommend exploring this approach!
