For this Automation, you will need either the Elgato Eve Weather or Eve Degree and any HomeKit enabled light bulb or light strip that can be set to various colors. In this example, we will be using Philips Hue light-strip and an Elgato Eve Weather sensor. We will also assume that you already have these items installed.

Step 1 – Open the Elgato Eve application


Step 2 – Navigate to the Scenes tab second from the left at the bottom of the screen


Step 3 – Toward the top of the screen, you will see three separate tabs, Scenes, Timers, and  Rules. Select the tab for rules


Step 4 – Toward the bottom of the screen tap “Add Rule”


Step 5 – Here you will be faced with a quick diagram of how to make a rule. Tap next or tap anywhere on the screen to advance.


Step 6 – Tap “Add Value Trigger” (this item is what will trigger the color change of the lights)


Step 7 – From this screen, you have two options. You can select a room to find an accessory that we want to uses or you can scroll down and select the type of Value Trigger. Doing either will present you with the Value Trigger options available. For this example, we will select temperature because I think it will be less confusing.


Step 8 – As you can see I have many temperature sensors available but only one outside which is labeled “back deck”. Select the one you have labeled for your Elgato Eve or Elgato Degree by toggling the button on.


Step 9 – By toggling the button on you are then presented with a new set of options to specify what you are trying to accomplish. For this new setting, I am going set a new range for anything less than 60 degrees. I will do this by tapping the specific option first.


Step 10 – Now I am greeted by the ability to set the parameters to less than, equal to, or greater than. I am going to go with an ice blue color so I will set the parameters to “Less than” or <.


Step 11 – Now I will need to adjust the temperature setting to the 60-degree mark that I wish To have triggered the light color adjustment. Using the arrow button I will tap down until I get to 60 degrees.


Step 12 – Now I just need to Tap the “Add” button in the top right corner of the screen


Step 13 – The next screen will allow us to add additional conditions for the automation. Since we already included a condition in the “Trigger Value” set up we can skip to the next step by clicking “Next” in the top right corner of your screen.


Step 14 – Now we will need to set the scene which will include the power state and color of the lights we wish to coordinate with the temperature. We do this by scrolling to the bottom of the screen and tapping “Add Scene”.


Step 15 – Tap “Add Actions”


Step 16 – Here we will select the room that we have the color changing light installed and set up. For this example, I am using my living room tv light-strips. So I will select Living- Room.


Step 17 – Find the device or devices in my case and toggle the power option for each device and select the “on” option.


Step 18 – Next Toggle the Color option directly below the Power Option. This will bring up a little white dot that if pressed will bring you to a selectable color wheel.


Step 19 – Tap the white dot to bring up the color selection screen (You will need to do this one at a time)


Step 20 – Pan around on the screen until you find your desired color. Tap the plus button to add the color to your favorites in case you wish to set additional lights.



Step 21 – In our case, we do have an additional light so I will tap on the white dot and instead of panning around on the color wheel I will just tap the favorite color that I just added. Then click on the back button to take me back to the living-room screen.


Step  22 – Now we just need to tap the “Add” button in the top right corner of our screen.


Step 23 – Click “Next” in the top right corner of your screen


Step 24 – You will need to name the scene that you just created and select an icon for the scene. I’m going to name mine “Baby it’s cold outside” and select the icon that reflects a thermometer.


Step 25 – Click “Done” in the top right corner of the screen

That is it you are all set. Now when the temperature outside is less than 60 degrees your lights will turn on and change to the color that you selected. You can repeat this for as many different outside temperatures that you like and by doing so a quick glance at the lights will tell you about what temperature it is outside. Have fun and share other recipes that you create with us.
