The article highlights practical Raspberry Pi projects using Home Assistant, a free, open-source smart-home platform that connects devices from different manufacturers and triggers automations based on events such as NFC scans, phone charging and electricity usage. It presents the system as a flexible way to move beyond basic lighting controls, with projects ranging from physical media controls to automated bedtime routines and appliance alerts.

Home Assistant OS officially supports Raspberry Pi 4 and 5 devices with at least 2GB of RAM and a 32GB microSD card, and the software has more than 1,500 integrations. NFC cards can launch films or playlists, charging a phone can activate a conditional “good night” routine, and a power-monitoring smart plug can detect when a washing machine has finished; the article notes that many of these projects require little or no additional hardware.
