I’m new to automating with Homey Pro. How do I create a “Movie Time” flow to smoothly dim the Family Room lights from the current level to 15% over 20 seconds? My dimmer switch is a GE Enbrighten.
Look at fe
[APP][Pro] Chronograph - Adds precise timer, stopwatch and transition functionality to Homey
There might be a “duration” slider when setting the dim level.
In my opinion the easiest way is to use the build-in option Duration… of the flow card Dim to… itself, as @Rmb already mentioned. However, this is not supported by all lamps.
To open the menu, right klick on the flow card.

Not all lights have the option for duration. For example every light presented by Zigbee2MQTT and I think I missed it with Matter lights when I tried using Philips Hue lights with Matter.
My lights do not have the option for Duration, so, in Advanced Flows, I did multiple steps one second apart to dim the lights. Unfortunately, I do not know how to start from the existing light level, so, I start at 50% down to 15%.
When you don’t mind using scripts, you can use this one below;
It dims a light from it’s current level to the level you saved in a variable. It automatically dims up or down to that value;
You can use flow card “Run code with argument”
Just copy/paste this script, and enter the variable name which holds the desired dim value (0.01 - 1)
Enter the lamp name as argument in the flow card
/* Dim-- a light in steps to [variable] level */
// Use flowcard "Run code with argument",
// the argument is the lamp's name
// (for a media device for it's volume: device.class = amplifier, volume = volume_set).
// USER INPUT
// For dimming to a Logics variable value (0.01.01 - 1),
// enter variable name here
let varName = "NightDimlevel";
// Enter a delay time (for the next dim level)
var waitForDimlevel = 750; /* time in ms */
// Enter the value to increase the dim level with
var myDimlevelStep = 0.02;
// User input end
let myLight = args[0];
// only for testing with console
//myLight = "Lamp Voorraam";
var myDimlevelEnd = ''; // don't change this
if (myLight == '' || myLight == undefined) {
console.log ('Missing argument, enter a device name at flowcard argument field');
return(false);
} else {
// Reading the variable value
// and updating 'myDimlevelEnd'
const logicVars = await Homey.logic.getVariables()
for (var iLogicVar in logicVars){
if (logicVars[iLogicVar].name == varName)
myDimlevelEnd = logicVars[iLogicVar].value
}
log(`\n- Value from logics var [${varName}]: ${myDimlevelEnd}\n`)
var waitTime = ''
// Get all devices
const devices = await Homey.devices.getDevices();
// Loop over all devices
for (const device of Object.values(devices)) {
if (device.name == myLight) {
// If this device is a light (class)
// Or this is a 'What's plugged in?'-light (virtualClass)
if (device.class === 'light' || device.virtualClass === 'light' || device.class == 'button') {
// Get the current dim level of the device
var currentDimlvl = ''
currentDimlvl = device.capabilitiesObj.dim.value
// Just to inform you while testing
await log(`- Current Dim level: ${currentDimlvl} \n- Wait for ${waitForDimlevel}ms between each step of ${myDimlevelStep} `)
// this works, but myDimlevelStep has to be rounded
if ( myDimlevelEnd >= currentDimlvl ) {
await log("- " + myDimlevelEnd + " > " + currentDimlvl )
for (let step = currentDimlvl ; step <= myDimlevelEnd; step += Number(myDimlevelStep) ) {
// for (var i = 0; i < myVar.length; i+3) {
// every three
// }
await wait(waitForDimlevel);
step = Math.round((step)*100)/100; // round to 0.00
log(`\nDimming ${device.name} to ${step}`)
// decreasing the dim level
await device.setCapabilityValue('dim', step)
.then(() => log('OK'))
.catch(error => log(`Whoops an Error!:`, error));
if (step <= 0.03) {
device.setCapabilityValue('dim', 0.01);
}
// just in case, quit if 'step' has become zero or 1
if (step < 0.01 || step > 0.99) {
break;
}
}
}
if ( myDimlevelEnd <= currentDimlvl ) {
await log("- " + myDimlevelEnd + " < " + currentDimlvl )
for (let step = currentDimlvl ; step >= myDimlevelEnd; step -= Number(myDimlevelStep) ) {
// for (var i = 0; i < myVar.length; i+3) {
// every three
// }
await wait(waitForDimlevel);
step = Math.round((step)*100)/100; // round to 0.00
log(`\nDimming ${device.name} to ${step}`)
// decreasing the dim level
await device.setCapabilityValue('dim', step)
.then(() => log('OK'))
.catch(error => log(`Whoops an Error!:`, error));
if (step <= 0.03) {
device.setCapabilityValue('dim', 0.01);
}
// just in case, quit if 'step' has become zero or 1
if (step < 0.01 || step > 0.99) {
break;
}
}
}
}
}
}
}
return(true);
Here you see the lamp name as argument in the flow card

I know that, and I already pointed that out:
I have a Fibaro Walli Dimmer in use and this feature is also not supported.
What I don’t know, however, is if the reason for this is that the device doesn’t technically support this feature, or if the feature isn’t implemented in the Homey Fibaro app.
Thank you @Peter_Kawa ! Not knowing anything really about Script programming… I did some tinkering and figured everything out! Great education for me!

YW!
I’m no programmer either, I built this script a while ago with all info I could find. And no cheatGpt of course
