Busy Light with ESP8266 mini D1 and Home Assistant

Working at home is nice, having the chance to have my own room for that is ever more lucky. But still I'm working at home and family just walk in whenever they want and it's sometime not the best moments :)

I found this useful 3D printed case for this project :

Corona BusyLight by SailorCM

This is a busy light indicator - it can be used to indicate, that there is already someone or too many people inside a shop, room or something else. The bottom-part has been designed to hold an ESP32 or ESP8266, connected to a neopixel-ring, placed above the lightguide-part. source for esp32/esp8266 can be used from:https://www.hackster.io/benedikt-hubschen/office-busylight-1a8e30

I already had on ESP8266 mini D1 available so I needed to buy this 12Led ring, I found it on amazon here :

If you need some ESP board; you can find the one I used here :

The wiring is simple and very easy to realise :

Now everything is solder, you need to use ESPHome to send this config to the ESP

When you have tested everything, you can assemble and glue (I glued the led to the white part

In Home Assistant it looks like this :

You can now make all kind of automation with Home Assistant, one of my automation is with a motion detector :

If someone comes between 09am and 5pm during the week day, it switch to red light ^^

My 3 yo kid now have to understand RED, don't come, GREEN, you can come :)
