![]() I'm not sure how difficult it would be to program this in J. Basically the concept is not that difficult. When the coordinates are stable again you notify the car is parked again and so on. When the car moves out of the new geofence you give a notification the car is moving. From that moment you define your new geofence location. When you see that the coordinates are stable, for let's say 5 minutes, the car is presumed parked. The idea is that you constantly check the traccar coordinates. As I explained before I wrote a C program that queries the Traccar MySQL database (not the default H2 database). I'm not sure how much time a J implementation would take. Measuring current in between these high surges might mislead you of the true long duration power consumption. Making a radio connection uses a lot of power. Only then you know how much a device consumes. Make sure that whenever you measure the power consumption that you average over a longer period of time (several hours). I'll keep this in mind, it might come handy. One disadvantage is that you don't have tsmgeek ACC status or motor shutdown options. Only traccar data on a 1 minute interval will use about 40 MB/month. #TRACCAR GEOFENCE INSTALL#I do advise to install a firewall on your cell phone and block Google updates. And when in the neighborhood of a wifi point your cell phone data costs will be limited. Also the build in cell phone battery makes sure the cell phone will continue even if cut of from the car battery. Given a car battery capacity of 100Ah only the cell phone would last for 100 days (not included the idle car power consumption). At this moment I use a Samsung Galaxy SII+ that consume on average less then 40mA/h (including the 12V -> 5V adapter). ![]() Measuring the power consumption of some cell phones I found out that there's a lot of difference in power consumption. I was a bit concerned that car trackers would consume lots of power. Just for your information I use an old cell phone. But I do hope it finds a place in Traccar. I'm not sure if dynamic geofencing will become a new buzz word or that it already exists. This dynamic geofencing helps me notifying that the car is moving without me. The new position is then the new/current geofence area. This steady state period is used the rule out traffic jams. The program considers a new steady position after the car stays motionless after a certain time ( 5 min. car is parked) it creates a new geofence around it's current position and mails me the current position. ![]() However when the C-program detects a new steady position (i.e. Whenever the car moves out of the, in the C program defined geofence area, the program send me a email that the car is moving. For this I wrote a (C) program that queries the Traccar MySQL database every ten seconds or so in order to find out the current position of my car. Hi, I use Traccar for a long time now and I'm very pleased with your work! Please, please keep up the good work!Īs a suggestion (not sure if this is already possible, if so let me know) I would like to introduce dynamic geofencing. ![]()
