Yabby - How to set up Man Down Alerts

The Yabby has the ability to configure "Man Down" alerts - and can send an alert to the server if the asset has not moved (defined as no accelerometer movement) for a configurable period of time. This is available on all versions of the Yabby.

The following settings are available, defaults are shown


Man Down Digital Input
Digital Input bit to set when man down is activated
Man Down Timeout Settings
If the Man Down Timeout will be Disabled, or in Minutes, Hours or Days
Man Down Timeout
Number of minutes/hours/days until Man Down DI is activated
Man Down Set/Clear
What to do when Man Down is set or cleared.

Options are:

  1. Disabled: Do nothing
  2. GPS Trigger a GPS fix, to be uploaded at a future event (heartbeat, movement detection, etc).
  3. GPS and Upload: Once Trigger a GPS fix and attempt an upload. If the upload fails, then it will wait until the next event (heartbeat, movement detection, etc).
  4. GPS and Upload, Retry: Trigger a GPS fix and attempt an upload continually, until it successfully connects to the server.

For the Wi-Fi version, GPS fix is replaced by Wi-Fi lookup and is equivalent.


Example

Send an alert to the server when the device has not moved for 12 hours:

We can apply these parameters (How to change parameters):


For an alert in TG, set up an alert with these conditions:

i.e. alert when Digital input 1 (or whichever input we have set up for Man Down) - becomes active.

When the device does not move for 12 hours, an upload will be sent to TG, and then this alert will be activated.

Tool Tracking with the Yabby

The Yabby is the perfect device for tracking small assets such as power tools. It's compact form factor means that it can be easily attached or concealed on small assets. Often the goal in tracking power tools is just figuring out where on earth the operator has left the tool once they have left site! 

The default settings on the Yabby GPS are perhaps not the best suited for this application. As they are:

  • Out of Trip
    • 12 hour heartbeats. This is a GPS fix and an upload every 12 hour
  • When Movement is Detected by the Accelerometer:
    • Upload on Movement; Start Trip
    • GPS records position log every 15 mins, uploads upon end of trip
    • Upload on no Movement detected for 5 minutes; End Trip

If the operator was using the tool for the day, might be more likely that they use a drill for example for 10 min, put it down for 10, pick it up again etc. This would result in a lot of unnecessary uploads, draining battery life. 

We can instead set the device up for one daily upload (or a few Scheduled Uploads) - and then set up Man Down alerts so we get an upload when the tool has been sitting still for a while - so we know where it has been set down with the minimum number of uploads - and longest battery life!
