node-enocean-dimmer

a dimmer for eltako devices (FUD14, FUD14-800 W, FUD61NP, FUD61NPN, FUD71, FSG14/1-10V, FSG71/1-10V, FSUD-230V) the dimmer implements an EEP similar to A5-38-08 (as per the Eltako documentation).
It is intended for use with node-enocean

installation

npm install node-enocean-dimmer

usage with promises

var enocean      = require("node-enocean")
var Dimmer      = require("node-enocean-dimmer");
enocean.listen( "/dev/ttyUSB0" )

enocean.on( "ready" , function( ) {
    var dimmer = new Dimmer( enocean , process.argv[ 2 ]  )
    dimmer.speed = "80"
    switch( process.argv[ 3 ] ) {
    case "teach" :
        dimmer.teach( ).then(enocean.close)
    break
    case "off":
        dimmer.off( ).then(enocean.close)
    break
    default:
        dimmer.setValue( process.argv[ 3 ]).then(enocean.close)
    break;
    }
})

usage with async await

var enocean      = require("node-enocean")
var Dimmer      = require("node-enocean-dimmer");
enocean.listen( "/dev/ttyUSB0" )

enocean.on( "ready" , async function( ) {
    var dimmer = new Dimmer( enocean , process.argv[ 2 ]  )
    dimmer.speed = "80"
    switch( process.argv[ 3 ] ) {
    case "teach" :
        await dimmer.teach( )
    break
    case "off":
        await dimmer.off( )
    break
    default:
        await dimmer.setValue( process.argv[ 3 ])
    break;
    }
    enocean.close()
})

the dimmer implements the following interfaces:

.setValue(x) sets the brightness level x must be in the range 0 - 100
.teach() send a learn telegram to teach in the sensor
.off() send a switch off event to the connected devices
.speed sets the dimming speed. Value must be two characters with a value between 01 and ff (hex) where 01 is fast and ff is slow.
