We are monitoring temperatures through IoT sensor and we are using Graph panel to display them. The data are streamed from InfluxDB every 15 minutes with different timing.
I am wondering if it’s possible to calculate and display directly in Grafana the difference between two temperature/value. The values come from a different measurement.
The print screen attached shows the temperature form the Supply air vent and the Return Air vent.
Any chance to display the delta T value = Supply Air temp - Return Air temp?
The value doesn’t have to be displayed on the Graph. It can be displayed on a Singlestat panel.
