Dependency not specified in installation documents

The bluetooth-hci-socket package needs to be installed. This should be included in the package.json file so it is installed automatically.

pi@raspi4:/usr/local/lib/node_modules/homebridge-automation-bluetooth-presence $ automation-bt-detect-devices
internal/modules/cjs/loader.js:638
    throw err;

Having the same problem while running automation-bt-detect-devices. Currently running node 8.9.4 on a PI 4 tried to install the bluetooth-hci-socket dependency by hand but had no luck and got a lot of errors similar to the one below. Which node version is best to run this library without any issues?

@lucadegasperi , you may want to install this instead

https://www.npmjs.com/package/@abandonware/bluetooth-hci-socket

apparently, bluetooth-hci-socket is not maintained
