Saving the doorbell visitor history to a file and displaying it

Setup, Configuration and Use Scripts & Rules
1

Hi All

This is my current rule which works, most of the time.

What occurs is it retrieves the image from the Doorbell and places it into the visitor-history folder just fine. What it fails to do reliably is copies the latest file from the at folder into /html and calls it lastvisitor.jpg

When I open the file using a browser http://IP/html/latestvisitor.jpg its quite old.

Any suggestions?

Thanks guys!

rule "Save Local Visitors History on Door Bell"
    when
        Item DoorBird_DoorBell received command ON
    then
        if(gPresenceSensors.state == ON){
        Echo_LivingRoom_TTS.sendCommand('Theres someone at your Front Gate')
        }
        if(gPresenceSensors.state == OFF){
        sendBroadcastNotification("Theres someone at your Front Gate")
        }
        logInfo("DoorBird", "DoorBell pressed by Visitor")

        var t = now
        var cmd = 'wget http://user:pass@192.168.0.141/bha-api/history.cgi?index=1 -O ' + OPENHAB_DIR + 'vistors-history/'
        cmd = cmd + t.getYear
        if (t.getMonthOfYear < 10) cmd = cmd + '0'
        cmd = cmd + t.getMonthOfYear
        if (t.getDayOfMonth < 10) cmd = cmd + '0'
        cmd = cmd + t.getDayOfMonth
        if (t.getHourOfDay < 10) cmd = cmd + '0'
        cmd = cmd + t.getHourOfDay
        if (t.getMinuteOfHour < 10) cmd = cmd + '0'
        cmd = cmd + t.getMinuteOfHour
        if (t.getSecondOfMinute < 10) cmd = cmd + '0'
        cmd = cmd + t.getSecondOfMinute
        cmd = cmd + '.jpg'

        if(vTimeOfDay.state != "DAY") {
            sendHttpGetRequest("http://user:pass@192.168.0.141/bha-api/light-on.cgi")
        }
        Thread::sleep(1500)

       executeCommandLine('wget http://user:pass@192.168.0.141/bha-api/history.cgi?index=1 -O ' + OPENHAB_DIR + 'html/latestvisitor.jpg')
       executeCommandLine(cmd)
end

Iā€™d suggest breaking the rule into parts and testing with a lot of logging:

  • Test the OpenHAB part separately - replace the sendHttpGetRequest and executeCommandLine with ā€˜logInfo(ā€œYourRuleNameā€, ā€œTest <ā€ + cmd + ā€œ>ā€)ā€™ to prove the command, and add similar logging to the GetRequest.
  • Test both parts from the command line via wget.

Without logging, all code works perfectly! :wink:

Donā€™t forget you may be fighting browser caching too
