Advanced Commands
A new feature has been introduced in SMS Lite Firmware Version 2.1 to enable you to
"debounce" the inputs.
The purpose of this feature is to prevent the SMS Lite from sending multiple messages
when connected to devices such as float switches, which can switch on and off several
times before settling (due to wave action in the tank). You need to programme a delay
before the text message is sent by the SMS Lite.
The trigger point / device that is connected to the SMS Lite must stay in that state for
the ‘debounce’ time that is set, before the SMS Lite will send a text message alerting
you of a status change.
Implementation
The delay is configurable and you can select one of the following options: 0, 5, 10, or 30
seconds, or 1, 5, 10, or 15 minutes.
The debounce value is "global" to all inputs and you cannot specify different values for
each input.
If the SMS Lite is connected to a device that will not be affected by this you do not need
to programme this as the default value is 0 and there will be no delay.
Configuration
Programme the
‘debounce’ option use the following instruction:
#[PIN][space]<object>:<item>=<value>[dot]
#12345 site:debounce=value.
e.g #12345 site:debounce=1min
The value must be written in the following format "0 sec", "5 secs", "10 secs", "30 secs",
"1 min", "5 mins", "10 mins", "15 mins"
For example “
#12345
site:debounce=
10 secs.”
Clearing all of the SMS Lite configuration settings:
#[PIN][space]Defaults[dot]
Note: This command will also clear all the programmed telephone numbers
