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

thingiverse

Just a little mount for a WeMos D1 Mini (16MB) to monitor conditions inside a drybox. I've added mounting plates for a 18650 battery-holder, 26650 might work too, as well as scripts. This will fit my drybox; other designs will work with some holes drilled in to mount it on the outside and cables driven through to connect a BME280. The script reads a BME280, monitors the battery voltage, puts this data on an OLED-display and provides a simple string for environmental-data. You can use it to monitor conditions inside and outside your home.
