Weather display

This is an enclosure for a 20x4 LCD display (2004A) with an I2C interface. It is controlled with a sonoff board, which has been upgraded with the tasmota firmware.
It also has an opening for a small motion sensor (AM312), so the display light only switchs on, when I'm standing in front of it.
For controlling it (means getting the weather data from an internet service and formatting it to fit properly into 20x4) I'm using a simple Node Red flow.
