This command activates/deactivates the unit’s power saving mode (sleep
mode). When power saving mode is activated, the unit will go to sleep after
2 minutes as long as no communication activity is detected on the GPRS
or SMS channels. If there is communication activity when the 2 minutes
expire, the unit will wait for 1 minute of communication inactivity before
going to sleep.
When power saving is deactivated the unit will never go to sleep and will
cancel any previously defined power saving activation timer.
When the unit reaches sleep mode, a low power consumption state is reached
on which only an input or a previously user defined timer expiration can
make the unit go back to normal mode. On sleep state, an input-change
detection or the wake-up timer count are the only functionality available.
This command includes as optional field an input mask to indicate which
inputs to monitor when in sleep mode. If no input mask is specified, all
inputs are monitored, meaning any input change may awake the unit. A
wake-up-time optional field is included to indicate the unit how long to stay
in normal mode after awakening before going to sleep again. If not specified
or if the special string
DDDD
is entered, the default value of 2 minutes is used.
The communication timeout used when the unit is ready to go to sleep while
it has detected over-the-air communication activity is also an optional field
that defaults to 1 minute. The last optional field is the wake-up-interval
which is used to awake the unit on a time basis. If this field is not included
the unit will not wake up on a time basis. The message has the following
format:
