The Yabby can be configured to use alternate logging parameters based on the time of day. The time of day which alternate parameters is used is termed "After Hours"


They Yabby can also be configured to alert on 'movement'. What is meant by movement varies depending on the parameters used. 

If the accelerometer wake-up filter is enabled (default), The filter only starts a trip when it has seen 1 seconds worth of above-threshold movement in a 4 second period, or repeated short movements over several 4 second periods.  if the filter is disabled, any small jolt will trigger an upload. 

See the Movement Detection setting in the Yabby System Parameters for more details. 


Examples:

1. "Work Hours" 8am - 6pm Mon-Fri. During this time we want a position update every 3 hours. The asset should not move at all after hours, and we want an immediate update when this occurs, as well as a position uploaded every 15 minutes if it continues moving - so we can track the asset.


Add the following parameter tabs: 

  1. Basic Tracking
  2. After Hours Movement Detection
  3. After Hours Setup


The defaults for After Hours Basic Tracking (12 hr heartbeats) and Movement Detection (not used as we are using periodic tracking during the day) are OK to leave. 


Under Basic Tracking set:

This sets a position and upload every 3 hours during 'normal' hours. 


Under After Hours Movement Detection,


  1. Set Disable Wake Filter to Yes. This will wake the device on any small jolt or movement and cause it to upload it's position (Upload On Movement Detection is yes by default)
  2. Set Movement Logging Period and Movement Upload Period to 15 minutes each, so a position and upload is sent every 15 minutes - this also provides the opportunity for the device to receive an ASYNC message putting it into Recovery Mode every time it connects for an upload.   
  3. Set Optimise for High Frequency Movement Logging to yes, since 15 minute positions is high frequency logging. 


Under After Hours Setup, set your Timezone, DST information (if applicable) and time for each day. So for Monday to Friday we would set:


After Hours Start Time: 1800

After Hours End Time: 0800


And Saturday and Sunday  


After Hours Start Time: 0000

After Hours End Time: 2400


Note if Start and End were both to be 0000, After Hours is disabled and there will be no After Hours period for that day. 



Setting up an Alert in Telematics Guru

With the above setting - when movement is detected after hours - the device will go 'in trip' and the Ignition (bit 0) will be set to 1. 

This can be used for alerting in Telematics Guru.

Either use the wizard to set up an After Hours Alert - useful if you want the same alert for other device types - that also report movement during work hours. 

Or use the Ignition On alert. (The ignition bit will only come on After Hours with the above OEM settings)
