====== Alarm SMS ======

The user can be informed by SMS about change of the state of the alarm point.

SMS text can be defined by user, but in most cases is used a default form, which includes:
  * **confirmation code** (usually a letter and a few digits)
  * the time at which the reported alarm condition occurred
  * project and data point name
  * the value of the data point


The user can acknowledge an alarm, if he has sufficient rights to do so, by sending an SMS to the phone number, from which the message was originally sent.

To acknowledge the alarm, it is necessary to write the keyword **ok** followed by a space and the received confirmation code. E.g.:
<code>ok s44</code>

After successfully processing the command, a confirmation SMS is sent to the user summarizing which alarm has been confirmed.
