Notes:
●
On start-up, if the first value is already below the threshold, that is considered a state transition. In this
case, the first value of 0 will trigger an MQTT publish.
●
When the value increases above the threshold (plus the hysteresis), we publish again.
●
When the value decreases below the threshold, we publish again.
10.2.6 HIGH RATE
The “High Rate” rule will trigger on “high rate of change”.
Trigger when the enriched register value has changed at a rate
greater than
a certain rate.
Note: A counter is always increasing. A drop in value is taken as a rollover. Therefore, for an 8 bit counter (range 0 -
255) a change in value from 254 to 253 is an increase of 255 not a decrease of 1
This event is only applicable to Input Registers and Holding Registers, not Discrete Inputs and Coils.
It is only applicable to numeric data types and the counter data type:
