The Restoral Margin is used for the upper and lower thresholds and requires the
measurement value to cross back over the threshold a certain amount before a new
event is reported. This prevents excessive event messages if the measurement is at or
near the threshold.
For example, consider an upper threshold set at 15V and the restoral margin set at 1V. If
the measurement initially exceeds 15V then an event is generated and a message is sent
to the network. The measurement must now drop to 14V and then exceed 15V before
another event is reported.
The restoral margins are
unsigned
values with units of 10mV (range is 2.55V). If a
restoral margin is set to 0, it is disabled.
Periodic reporting is described in the section Periodic Reports.

Report on Change Mode
Report on Change mode is set when byte 0 of the payload is set to 0x01. The remainder
of the payload is defined in the following table.

Periodic reporting in 1 minute or 1 hour intervals. Default is 0 (disabled)

3-4
Analog measurement increase
5-6
Analog measurement decrease
If the increase or decrease values are non-zero, then the sensor will send an alert any
time the analog measurement changes by the specified amount. For example, if the
measurement increase and decrease are set to 5V, then an alert is sent every time the
measurement changes 5V from the last report. The increase and decrease are unsigned
values with units of 10mV.
Periodic reporting is described in the section Periodic Reports.
