Misfit Bolt Javascript Interface

Thin wrapper around sandeepmistry/noble, that helps Misfit Bolt bulbs discovery, and allows turning them on/off and changing their color and brightness, as well as reading their currently set values. Currently support setting color and brightness via RGBA and HSB.

Prerequisites

To connect to the Misfit Bolt, you need BLE capabilities. See sandeepmistry/noble prerequisites for more details.

Setup

npm install misfit-bolt
