How to display temperature and humidity readings from CO2 sensors on Dashboard graphs

Adding a CO2 sensor to a single sensor card provides two graph options:

  • Time series
  • Heatmap

When the card is set to a 1x1 size, both options display only the numerical values of CO2, humidity, and temperature readings. 

Expanding the card lets you see the time series or heatmap view, depending on the selected graph type.

Currently, neither option in Studio allows incorporating temperature or humidity readings into the graph view. These readings will remain as numerical values on the side.

However, there is an unofficial workaround that allows you to display this data in a graph. 

Temperature readings

  1. Create an emulated Temperature sensor in Studio. See How do I create an emulated device? for instructions.
  2. Go to Project Dashboard.
  3. Create a New Card.
  4. Select Multiple Sensors.
  5. Choose a Temperature card.
  6. Add both the Emulated Temperature sensor and the CO2 sensor to the same card.

Humidity readings

  1. Create an emulated Humidity sensor in Studio. See How do I create an emulated device? for instructions.
  2. Go to Project Dashboard.
  3. Create a New Card.
  4. Select Multiple Sensors.
  5. Choose a Temperature card.
  6. Add both the Emulated Humidity sensor and the CO2 sensor to the same card.
