Help with alarm and computed attribute

Hi,
Need to obtain an alarm when the attribute Io3 get the 100.00% value. Device uses gps103 protocol. I'm confused on how to do that. Actually I configured this parameters.

Description: Level Up
Attribute: Alarm
Expression: Io3 == "100.00%" ? false : true
Type: String

I will appreciate any help.

You need to return alarm key. Something like this:

io3 == "100.00%" ? "someAlarm" : null

Note that all attributes always start with low case letter.

Thank you very much friend!

Hi Anton

I have a similar question. I want to trigger alarm/event in events table when I get a particular attribute condition.
For example I want to trigger ignitionOn when I receive ot1 == true;

I tried using:
Attribute: Event/Alarm
Expression: ot1 == false ? "ignitionOn" : null

When I do the testing using ? button, it shows ignitionOn. But there is no insert in events table nor in attributes in position table.
I tried restarting the server also. Can you tell me what I am doing wrong here.

Thanks for your support.

Where does it show "ignitionOn"? You should be using Alarm, not Event.

I tried with Alarm also.
It shows ignition on from the test option (?) while creating the computed attribute.

Then it should work the same way for actual positions. Probably you haven't received any new ones.

I am getting data every one min. I have not put any duplicate filter so every one min a new row is inserted.
I tested with below condition also as ignition is coming in each row in position table.

ignition == false ? "ignitionOn" : null

Silly question. Have you linked your computed attribute to the device?

yes of-course :)

Do you want me to share credentials with you to frontend over an email?

Sure, I can have a quick look.

Sent you details on support@traccar.org.

I can see that your device has time in the future and doesn't update location. Can you please next time check everything more carefully.

Thanks Anton. Let me check it out why its showing wrong data. From socket its showing correct time as per utc.

I will check and let you know once I am able to fix it.
