This little box shows the inside and outside temperature as well as the weather forecast on the display. The round window on the left lights up in different colors depending on whether the laundry has been washed or the mail is in the mailbox. An “old radio” design was aimed for.
An ESP32 development board, including sensor and display, is installed. The external sensor data are sent by ESP-07s with different sensors via WiFi as a UDP network protocol.
