Hello,
I have Teltonika GH1201 device.
I configured 2 connection notifications:
- no coordinates
- no data
 
I set the time interval = 1 minutes and set correct e-mail address.
Device sends a signal every 40 seconds.
 
When Teltonika GH1201 hasen't got GPS signal, the website GPS-Trace Orange show "0 Amount of satelites" and doesn't send notification "No Coordinates" by e-mail. In statistics I have 0/5 hourly notifications e-mail.
 
When I take out the sim card from device, the website send me 2 e-mails "No Coordinates and No Data".
 
Please help in solving the problem, why the website doesn't send e-mail when lack of GPS signal.
 
Regards and waiting for a reply.
Lukasz

Possibly satellites were not locked but positioning data was still sent:
2015-04-02 21:46:45 0x3 {"t":1428000405,"f":3,"tp":"ud","pos":{"y":51.2040045,"x":22.5428383,"z":0,"s":0,"c":0,"sc":0},"i":0,"p":{"param69":1,"param240":0,"gsm":4,"pwr_ext":12.159,"battery_charge":0}}
2015-04-02 21:47:25 0x3 {"t":1428000445,"f":3,"tp":"ud","pos":{"y":51.2040045,"x":22.5428383,"z":0,"s":0,"c":0,"sc":0},"i":0,"p":{"param69":1,"param240":0,"gsm":4,"pwr_ext":12.161,"battery_charge":0}}
 
Parameter ""sc":x" corresponds to number of satellites. So as you can see coordinates are present but sc=0.
Thus notification is not triggered.

From what you wrote, I infer that my device when lose the GPS signal, sends to the server the last known position.

Do I understand correctly ?

 

Please check now.

At 21:05 on 03.04.2015 I took the device to the garage where there is no GPS signal, but it's good GSM signal (Internet connection).

What information is sent by device now ?

 

Website didn't send me notification of the lack of GPS signal, when I took the device to the garage.

Now the website update the informations from the device and displays " a few second ago (03.04.2015 21:18:09), but displays 0 satellites.

 

The tracker GPS device will leave in the same place in garage for the time, when you can check what informations are sent to the server from my device.

device when lose the GPS signal, sends to the server the last known position.

The logic of the device is not known to me and I can not tell how it works.

All I can is to provide actual data received by our server.

Approximately at 21.19 the device has lost satellites: 

2015-04-03 21:18:39 0x3 {"t":1428085119,"f":3,"tp":"ud","pos":{"y":51.2034611,"x":22.5426433,"z":105,"s":7,"c":181,"sc":6},"i":0,"p":{"param69":1,"param240":1,"gsm":2,"pwr_ext":0.115,"battery_charge":0}}
2015-04-03 21:19:19 0x3 {"t":1428085159,"f":3,"tp":"ud","pos":{"y":51.2034611,"x":22.5426433,"z":0,"s":0,"c":0,"sc":0},"i":0,"p":{"param69":1,"param240":1,"gsm":2,"pwr_ext":0.086,"battery_charge":0}}

 

2015-04-03 21:19:48 0x3 {"t":1428085188,"f":3,"tp":"ud","pos":{"y":51.2034611,"x":22.5426433,"z":0,"s":0,"c":0,"sc":0},"i":0,"p":{"param69":1,"param240":0,"gsm":1,"pwr_ext":0.085,"battery_charge":0}}

And again as you can see it kept on sending position.

If there were no position in messages only then a notification would have triggered.

Can I set email notification, when sc=0 ?

or

Can you implement notification option in server, when sc=0 ?

 

Thanks for the reply.

Happy Easter

Unfortunately there is no such notification but a close functionality to what you have described can be achieved in our commercial products by:

1. creating a virtual sensor with parameter "sats";

2. setting a corresponding notification with type "Parameter in messages" and choosing "Parameter lack".

 

P.S. I doubt something similar would be implemented here in the nearest decade or would it be implemented ever.
