Colour therapy room

Hello all,

I’d like to share how I worked out an idea I had. We have recently installed a new relax room in our house with a sauna, bed, relaxing paintings and such. I thought it would be nice to also add colour therapy to the room using my Homey. To make this, I bought some RGB lamps (Ikea Tradfri and Philips Hue) and wrote some flows and HomeyScripts to make them continuously change color to create some kind of colour therapy. It works on all RGB lamps in a given room at the same time.
You can tweak the speed by changing the TherapyCounter (seconds before next colour is picked) and the increments on the current_hue variable (stepsize between two consecutive hue values/colours).
Therapy evidently starts with running the Therapy Start flow and stops with running the Therapy Stop flow. Here’s how I did it:

HomeyScript App

Create these three scripts in the HomeyScript website (https://homeyscript.homey.app/)

script 1: relax_init_colour

// initialize all RGB lamps in zone 'Relax room' to red
let devices = await Homey.devices.getDevices();
_.forEach(devices, device => {
    if(!device.capabilities.includes("light_hue")) return;
    if(device.zoneName != 'Relax room') return; 
    device.setCapabilityValue('onoff', false);
    device.setCapabilityValue('dim', 1);
    device.setCapabilityValue('light_hue', 0);
    device.setCapabilityValue('light_saturation', 1);
    device.setCapabilityValue('light_temperature', 0);
    device.setCapabilityValue('light_mode', 'color');
});
return true;

script 2: relax_set_colour

// set all RGB lamps in zone 'Relax room' to the hue value
// received in a parameter
if (args[0] === '') {
    return false;
} else {
    let hue = parseFloat(args[0],10) % 1;
    console.log(hue);
    let devices = await Homey.devices.getDevices();
    _.forEach(devices, device => {
        if(!device.capabilities.includes("light_hue")) return;
        if(device.zoneName != 'Relax room') return; 
        device.setCapabilityValue('light_hue', hue);
        device.setCapabilityValue('light_saturation', 1);
        device.setCapabilityValue('light_temperature', 1);
        device.setCapabilityValue('available', true);
        device.setCapabilityValue('ready', true);   
    });
    return true;
}

script 3: relax_set_white

// Set all RGB lamps to to white
let devices = await Homey.devices.getDevices();
_.forEach(devices, device => {
    if(!device.capabilities.includes("light_hue")) return;
    if(device.zoneName != 'Relax room') return; 
    device.setCapabilityValue('onoff', false);
    device.setCapabilityValue('dim', 1);
    //device.setCapabilityValue('light_hue', 0);
    device.setCapabilityValue('light_saturation', 1);
    device.setCapabilityValue('light_temperature', .3);
    device.setCapabilityValue('light_mode', 'temperature');
});
return true;

Better Logic App

Create two better logic variables:

  • boolean in_therapy = false
  • number current_hue = 0

CountDown App

Create a timer:

  • Timer TherapyCounter

Flows

Flow: Therapy Start
When This Flow is started
And -
Then

  • BetterLogic Set boolean variable in_therapy = true
  • BetterLogic Set number variable current_hue = 0
  • HomeyScript Run a script relax_init_colour
  • HomeyScript Run a script with an argument
    relax_set_colour [current_hue]
  • Flow Start Therapy - Delay

Flow: Therapy Stop
When: This Flow is started
And -
Then

  • BetterLogic Set boolean variable in_therapy = false
  • HomeyScript Run a script relax_set_white

Flow: Therapy Delay
When This Flow is started
And BetterLogic is true in_therapy
Then CountDown Start countdown timer TherapieCounter = 5

Flow: Next Colour
When: CountDown Timer reaches zero (0): TherapyCounter
And BetterLogic is true in_therapy
Then:

  • BetterLogic: Increment number variable current_hue = 0.1
  • HomeyScript: Run a script with an argument
    relax_set_colour [current_hue]
  • Flow: Start Therapy - Delay

Have fun with it.
Kind regards,
Joachim
