The following command sets the geofence (alert) radius around the specified L/L –  
{  
“req”: “card.location.mode”,  
“mode”: “periodic”,  
“lat”: 42.5776,  
“lon”: -70.87134,  
“max”: 100,  
“minutes”: 2  
}

If “lat” and “lon” are not specified, will those fields default to current L/L position? That appears to be the case with an experiment I tried.

regards, Rich …

Hi @richf ,

Yes - if the latitude and longitude are omitted from the geofence set request the most recent values are used.

Thanks
