This E-Ink dynamic display is powered by a ESP8266 System on a Chip. It connects to the local WiFi and reads calendar entries with the goal of displaying last Meetings in the meetings room.
It offers also a Web Interface that allows to send a custom Title and additional Content to be displayed on the E-Ink display.

It offers also a multi-cast DNS server so it can be accessed by a Service discovery (Bonjour) using a display.local URL instead of the IP.
