Hourly monitor and report via email low voltage warnings and daily voltage levels.

This applies to the RB333 and RB433AH with V3.11 or greater ONLY!

Low Voltage Report

This report is sent hourly to the email address in the voltmonitor script when the input voltage is at or below the alarm voltage.

ThisBox voltage is 12.5v

Daily Voltage Report

This report is sent daily at 11PM to the email address in the voltreport script.

Daily voltage report for aug/29/2008

23:00 = 12.8v
22:00 = 12.8v
21:00 = 12.9v
20:00 = 13.0v
19:00 = 13.0v
18:00 = 13.3v
17:00 = 14.1v
16:00 = 14.0v
15:00 = 14.0v
14:00 = 13.9v
13:00 = 13.9v
12:00 = 13.9v
11:00 = 13.9v
10:00 = 13.5v
09:00 = 13.2v
08:00 = 12.6v
07:00 = 12.5v
06:00 = 12.5v
05:00 = 12.5v
04:00 = 12.6v
03:00 = 12.6v
02:00 = 12.6v
01:00 = 12.7v
00:00 = 12.7v

Since recording started on 13:00:00 aug/28/2008
Maximum = 14.2v at 13:00:00 aug/28/2008
Minimum = 12.5v at 05:00:00 aug/29/2008

Requirements

/tool e-mail must be set correctly to send email,

/system ntp client must be set correctly for the correct time after a reboot,

/system identity should be set to identify the router in the Low Voltage Report,

and the following two scripts:

voltmonitor

The first is voltmonitor. It should be scheduled to run once every hour on the hour (or within a minute after) in /system schedule.

#set lowvoltalarm to desired alarm voltage in tenths of a volt. 125 = 12.5v
:global lowvoltalarm 125
:global highvolt
:global lowvolt
:global starttime
:global hivolttime
:global lovolttime
:global vh
:local thisbox [/system identity get name]
:global voltage [/system health get voltage]
:local thistime [/system clock get time]
:local thisdate [/system clock get date]
:local thishour [:pick $thistime 0 2]
:local emessage ($thisbox . " voltage is " . [:pick $voltage 0 2] . "." . [:pick $voltage 2 3])
:if ([:len $lowvolt] < 1) do={:set lowvolt 999; :set highvolt 0}
# set your email address in the next line
:if ($voltage <= $lowvoltalarm) do={/tool e-mail send to="youremail@yourdomain.com" subject="$thisbox low voltage" body=$emessage}
:if ($voltage > $highvolt) do={:set highvolt $voltage; :set hivolttime ($thistime . " " . $thisdate)}
:if ($voltage < $lowvolt) do={:set lowvolt $voltage; :set lovolttime ($thistime . " " . $thisdate)}
:if ([:len $vh] > 0) do={:set vh ([:toarray $voltage] + $vh)} else={:set vh [:toarray $voltage]}
:if ([:len $starttime] < 1) do={:set starttime ($thistime . " " . $thisdate)}
:if ($thishour = "23") do={:execute voltreport}

voltreport

The second is voltreport. It does not need to be scheduled. It is executed by voltmonitor at 11PM every day.

:global highvolt
:global lowvolt
:global hivolttime
:global lovolttime
:global starttime
:global vh
:local tvolt
:local thisdate [/system clock get date]
:local thishour
:local emessage "Daily voltage report for $thisdate\n\n"
:if ([:len $vh] > 0) do={
    :for x from=0 to=([:len $vh]-1) step=1 do={
        :set tvolt [:tostr [:pick $vh $x]]
        :if ($x = 23) do={:set thishour "00"} else={
            :if ($x > 13) do={:set thishour ("0" . [:tostr (23 - $x)])} else={:set thishour [:tostr (23 - $x)]}
        }
        :set emessage ($emessage . $thishour . ":00 = " . [:pick $tvolt 0 2] . "." . [:pick $tvolt 2 3] .  "v\n")
    }
    :set emessage ($emessage . "\nSince recording started on " . $starttime . "\n")
    :set tvolt [:tostr $highvolt]
    :set emessage ($emessage . "Maximum = " . [:pick $tvolt 0 2] . "." . [:pick $tvolt 2 3] . "v at " . $hivolttime . "\n")
    :set tvolt [:tostr $lowvolt]
    :set emessage ($emessage . "Minimum = " . [:pick $tvolt 0 2] . "." . [:pick $tvolt 2 3] . "v at " . $lovolttime . "\n")
# set email address in next line
    /tool e-mail send to="youremail@yourdomain.com" subject="Voltage Report" body=$emessage
}
# remark out the next line for testing to avoid resetting the voltage array
:set vh
