Power Cut Alarm

Hello Anton,

I was working on "Power Cut Alarm" Notifications. I want to know this alarm is generated by position ( as some other notifications are generated ) itself or by the device( by sending some code ).

Alarm is generated by device and stored in position.

Can you tell me when Power Cut Off Alarm happens what changes in the position row like some attributes values or anything other?

Alarms are reported directly from devices.

OK thanks. But I am not getting how power cut alarm is detected under what condition.

As I said, event is coming from device. You need to contact your device vendor for more information about alarms for particular device.

OK, thank you.

Hello Anton,

I have rf v16 mini gps with protocol h02 registered with traccar server. I also have got this red marked Power Cut alarm warning with that. I don't know what it means. Can I remove it from attributes?

You can remove it using computed attributes.

Hello Antion,

Can you help me please to make the expression for computed attributes to remove power cut alarm attribute?

Something like this:

alarm == "powerCut" ? null : alarm

Thank you!

Anton,

I am filling out the dialog box of Computed Attribute. So I am using your expression and what should be the Drop down menu's "Attribute" and the "Type"?

Attribute should be alarm. That's the one you want to affect, right?
