Creating a Custom Variable in Ubidots (Synthetic Variable)

If you need to create a new variable derived from your existing data (for example, an average, a conversion, or a mathematical combination), you can do this directly in Ubidots by creating a Synthetic Variable.

Step-by-Step Instructions​

  1. Open the Devices Section​

    In the top navigation bar, click on Devices.
    You will see a list of all your devices.
    Find your device and click on it.

  1. Add a New Variable​

    In the top-right corner, click the red + button
    and select Synthetic Variable from the menu.

  1. Select Device and Variables​

    On the right side, select:
    • Your device
    • The variables you want to use in your calculation

    On the left side, enter your formula.
    You can combine multiple variables and mathematical operators to create new logic.

Example Operations (format samples)​

1. Average of two variables

(temperature + humidity) / 2

2. Convert temperature from °C to °F

(temperature * 9 / 5) + 32

3. Difference between two pressure values

pressure_sensor_1 - pressure_sensor_2
