Thank you

You need to find out correct command format. You can try "DYD,123456#".

Traccar not correct send "stop/resume oil" on GT06 - not working.

Correct command for disconnect oil and electricity online:

787815800F0001A9584459442C3030303030302300A0DCF10D0A

303030303030 - this password = 000000

Correct command for connect oil and electricity online:

78781680100001A963484659442C3030303030302300A07BDC0D0A

It's work for me (send custom command).

@vsaranov, there are two different sets of GT06 devices. Traccar can send your format as well if you set "gt06.alternative" to "true". Only thing is that password is hardcoded to "123456" at the moment.

Anton, thanks.
Not working command “stop/resume oil” in traccar this is a bug or a feature?
The correct description of the protocol for GT06 links there, and the command server is not working.

There are two different versions of GT06 protocol with different command formats. Both are correct.

Clear. How to add control commands other format GT06?

If you are asking how to switch between two, you should read my first comment more carefully.

I read it, sorry did not understand.
Where should I search for and correct the format of the command sent?

You should add the parameter to the config file.

Thanks, all worked!
I'm change config file and replace password in Gt06ProtocolEncoder.class and repack zip (jar).

Hi, my traccar installation does not have this file "Gt06ProtocolEncoder.class.jar" Do I need to download and put it in /opt/traccar/lib ? Because I think that I need to change it. I have a new version of gt06 tracker, and when I send stopengine from the traccar system, it does not stop the engine, but when I send custom command like DYD,000000#, it works very well.

Hi kimnguu204, could you tell me if the unit GT06 is from Concox or is it another without brand with logo Accurate print in the unit. Thanks in advance.

@robert: Unit GT06 has Accurate logo printed it

Could someone help with the commands of locks and unlocks "turn ignition on and off", suntech st310u and GT06 equipments
