14.3. Example 3: Control an appliance
In this example we need to switch a 220V light bulb on or off via a suitable SMS message from a
specific number listed on the Micro Commander.
Hardware:
We connect light bulb to a 220V power source via the output 1 contact on the Micro Commander,
exactly as described in section 5.9
Configuration:
Using the setup software, we create a behaviour statement that will read as follows:
IF Message is received, containing "Lights on" from 0821231234 THEN Activate Output 1.
We create a second behaviour statement that will read as follows:
IF Message is received, containing "Lights off" from 0821231234 THEN Deactivate Output 1.
14.4. Example 4: Gate / garage door opener
In this example we need to open a gate in response to a missed call from any number in a list of
accepted numbers. This is an ideal method to control a communal gate in a complex.
Hardware:
Many gate openers require a pulse to open, and second pulse to close. We will use the output of the
Micro Commander to supply this pulse at the position where the open/close switch is normally
connected to the opener.
Configuration:
Using the setup software, we create a behaviour statement that will read as follows:
IF a Voice Call is received from any listed number
THEN Activate Output 1 for 1 Sec, Pause for 20 Sec, Activate again for 1 Sec.
14.5. Example 5: Contact to Contact relay
In a few instances it may be necessary to transmit the status of a contact to a remote point. Let us
use an alarm as example. If the alarm at your home sounds, you may want a warning light to switch
on in a remote location and a voice call to be placed to a specified number.
For this example, we will use two Micro Commander units, one at the local alarm system, and
another at the remote location.
Local Micro Commander Hardware:
We connect the alarm output (12V signal that drives the siren) to one of our inputs as described in
section 5.8. The positive wire from the alarm panel is connected to the +IN terminal, and the
negative wire is connected to -IN.
Local Micro Commander Configuration:
Using the setup software, we create the following behaviour statements:
St1 : IF Input Goes Active THEN send "alarm on" via SMS to +27833341234
St2 : IF Input 1 Goes Active THEN Place Voice Call to +27821121323
St3 : IF Input 1 Goes inactive THEN send "alarm off" via SMS to +27833341234
