Calculate Delta Between Values
I have a signal (kWh) that continues to grow over time (ex. 1000, 1025, 1078, 1090). I want to see its change in a line graph or other view. Provide a tile that calculates the change between values (ex. 25, 53, 12).

I thought this might be accomplished with a real-time expression, but I can't get it to work. Could it be as simple as =[CONSUMPTION(energy_kWh)]-Min[CONSUMPTION(energy_kWh)]? That works for single value but not for a chart. The example for calculating cost from power is close, but the kWh reading on devices is much more accurate over time. This is top on my list currently as seeing which devices are accumulating the most energy use (on the same chart, starting at 0) is very useful. I just used all my votes on this! Thanks for an awesome site and for taking feedback!
Thank you Initial State for posting my idea here. Excellent customer support :)
Glad to see this idea is getting some traction in the community
This would be awesome!
