WeMos/Lolin D1 Mini - Mount for Drybox + script for BME280

Just a little mount for a WeMos D1 Mini (16MB) to monitor the conditions inside a drybox.
I've also added a mounting plate for a 18650 battery-holder - 26650 might work too - as well as a script.

This will fit my drybox. Other designs will work too - you just have to drill some holes to mount it on the outside and to drive through some cables to connect a BME280.

The script reads a BME280, monitors the battery voltage, puts this data on a OLED-display and provides a simple string for the environmental-data.

You can also use it to monitor the environment inside and outside your home.
