As a long-time Home Assistant enthusiast, I’ve always been passionate about creating a seamless smart home experience. However, I’ve noticed that my family, especially the older generation, often finds touchscreens overwhelming. They’re too many submenus, too much scrolling—frustrating for anyone who isn’t tech-savvy!
This challenge led me to explore alternative solutions. I stumbled upon an innovative project using an ESP32-S3 microcontroller paired with a 3.5" IPS display and a rotary encoder. The idea is simple yet brilliant—replace the touchscreen with a physical knob for navigation. This approach forces the interface to be intuitive and straightforward, perfect for everyday use.
Here’s what I’ve learned so far:
- Hardware Setup: The device is compact, making it ideal for placement on a desk or nightstand. The rotary encoder provides tactile feedback, which is both satisfying and efficient.
- Software Integration: I’ve developed a local web interface that integrates seamlessly with Home Assistant using an API key. This setup ensures everything stays 100% local, eliminating dependency on external servers.
- User Experience: Early testing with my family has been promising. The physical knob makes navigation intuitive, and the interface is clean and easy to understand.
I’m curious to hear your thoughts—does a non-touchscreen approach appeal to you? How do you handle smart home control with family members who aren’t tech enthusiasts? I’d love to discuss this further and explore other innovative solutions together!
