Description A trafficlight connected to the internet
Owner  Tiefpunkt (tiefpunkt)

We have a traffic light in the space that can be controlled via the internet.

Hardware

  • Trafficlight
  • 3 5V LED Lamps (voltage uncertain)
  • 4-channel relais board
  • esp8266
  • Barreljack Power Supply (the small white thing in the top of the Photo)
  • The Multiswitch board
The PCB
the back of the pcb

Software

Control

Use Homeassistant to control the lights either directly or via automations

It's currently tied to the status - closed is red and open is green :)

ESP Home also provides a webinterface which is currently reachable at http://10.10.10.253/ (that's a DHCP IP so it will possibly change soon => TODO: Fix IP Address)

Pinout

You can find the pinout for the ESP here.
