Years ago, I spent a lazy afternoon building a small device to aid in remote troubleshooting my elderly relatives’ internet woes. As I had a hard time tracking down trouble via phone (“can you check if the IMAPS server responds on port 993?” was rately successful), I built a few LEDs and an ESP8266 microcontroller into a picture frame. Now there’s a traffic-light style box at each of my relatives’ house, and asking “are any lights red? Which ones? Okay, the internet works but your bank is down. Let’s take it from there…”
A few weeks ago, I decided to add the Home Assistant AOI, and make everything configurable without having to change the code via the Arduino API.
The result is now on GitHub: https://github.com/quantenlabor/hass-led-panel
Here’s a picture:
The LEDs look brighter than they are in reality. The IKEA picture frame makes for a nice and clean look; it’s also the most expensive component at 5.99 Euros.
The systems/entities to check are configurable via a built-in web server:
Soldering is minimal (3 wires).
Maybe this inspires someone :-)
