I wrote a new plugin for the BME280 sensor using the node-bme280 driver.
The code is here:https://github.com/atus/pimatic-bme280
The package is here: https://www.npmjs.com/package/pimatic-bme280
This is my first contact with coffee script and publishing an npm package so let me know if something needs fixing.
The plugin works for me, but if you find issues, please let me know on atus/pimatic-bme280#issues or submit a pull request.
