Questions about the use of custom attributes
Thank you, this works. Is there a list of how to refer to all attributes? "address,movement,contact" e.g. don't work.
There are some attributes that you can't remove (e.g. address).
OK I understand, but is there a list? Now it's just guesswork which work and which don't.
You can find keys for common attributes here:
https://github.com/traccar/traccar/blob/master/src/org/traccar/model/Position.java
the common attributes ink is down can i knw the new link please
Find the Position class in the source code. It's still there, but the path has changed.
Dear Anton,
I have a number of questions about using attributes.
Question 1: my gps103 based GPS trackers report the io1, io2 and io3 attribute. These show as either 0 or 1. What I would like to have is, per device (group), have a custom attribute with a logical name, which reports the assigned io1, io2 or io3 value. E.g.: I have a device group called "RFS 201" for which "io2" indicates whether some button is pushed or not. So I would like to have an attribute for all devices in the RFS 201 group called "Button" which report the io2 value. When I create a calculated attribute, I cannot select "io2" as the attribute assigned, but have to choose from a drop down list e.g. Contact, but in the calculation I can refer to io2 and read its value. But as a result, the calculated attribute shows as Contact, i.e. with the name from the drop down list. What steps do I need to do to get a new attribute called "Button" which shows the value of io2 in the status list with parameters?
Question 2: the filter.distance attribute requires a minimum displacement for the value to be recorded. Is there also a filter that does not record any excess movements, e.g. more than 1 km should be ignored? I'm refering to this list: https://www.traccar.org/configuration-file/
Question 3: I need to calculate distance when another attribute has a specific value. So, for example linked to question 1, I need a parameter activeDistance which accumulates distance traveled only when Contact = io2 = true / 1. Is there any reference on how to proceed?
Any help is greatly appreciated.
Thanks, best,
Luc
Greetings,
Dear @Luc Peulen have you managed to create custom attributes you mentioned in your first statement (Question # 3) ?
if yes please share the expression you used to calculate "Active-Distance" (current trip) by accumulating "distance attribute" and checking if ignition status is ON and not changed to OFF. Then resets the value to ZERO when ignition is turned-off. Your help would be much appreciated. Thanks
Dear Anton. Any reference as to how to hide such using user attributes? When I check Calculated attributes at the user level, it only shows me the calculated attributes I defined, but not attributes such as io1/io2/io3.
