Computed attribute for T12 battery level

Hi,

I am testing T12 tracker from VJOY . I would like to show the battery level in the frame status on the bottom of the page to the left. I think i have to set that in the computed attribute but i don't know how to do that .

Someone to help me please,

(864768010776778,ZC07,100218,A,5037.34518N,00305.63790E,0.189,163609,000.0)(864768010776778,ZC20,100218,163607,6,412,65535,255)

What's the good format expression to add in attributes ?

You don't need any computed attributes. Traccar will automatically display battery level if your device reports it.

Thank you for your reply . T12 tracker reports it in the hex like in the picture joined :

But i can't see it on the left windows "status" on the web server. Why ?

PROTOCOL :

Probably because your device doesn't report it, or at least it didn't report it in the last message (that you see in state).

In the picture in attachment you can see in the hex with the red circle the value of battery level so it report it isn't it ? it' s the last message

It's filtered, as you can clearly see from the log.

I thought that just position was filtered ... I will try to modify default.xml ? or traccar.xml ?

Are you asking me? You added filtering, so you should know better where you added it.

sorry anton but i have followed so much advices that i forgot where i add a filter . I just remove lines in default.conf and restart server

I removed the filters and it works . Thanks Anton
