Using the "On change" trigger condition is only useful when the stream data doesn't change much. When looking at data like temperature or accelerometer streams, there is always some jitter or fluctuation in the values. Using a rounding function within Flow minimizes, but doesn't eliminate this.
I would like to be able to alert when the current value has changed by a certain percentage or more.
Thanks for the update on a possible future feature.
As mentioned, it would be useful to have a percentage change option as mentioned. But, a simpler "Threshold Value" to indicate a minimum change in the actual value would also be useful. This could be similar to the "=" trigger condition where there is a "Threshold" value set but no "Reset" condition.
Either way, threshold percentage or threshold value would give pretty much the same triggering ability. Without requiring percentage, the M2X feature implementation may be simpler and would just require a bit more knowledge of the data values by the M2X user.
