So what is your conclusion after testing ? You are only going to use the frematic plus or want a solution for the tl-906 ?
I actually prefer the to-906 if I can find how to limit the data usage and actually make it go to sleep when the car is off
You can set the upload frequency for this device by sending a command through the server ?
And actually what is the reply of the device when you send the command: RCONF
Does it show SLEEP: OFF
If so you should turn it On.
im testing out two trackinf devices. the frematics plus and the tl-906 using hologram sim card. while the frematics goes to sleep while not moving, the tl-906 just keep transmitting the whole time. its using about 5-6 mb a day. it is hardwired to 12v plus is connected to acc so it knows when ignition is on. for the settings i ws playing around and i have it set at 30 seconds interval while acc is on and 30 minutes while acc is off and i have sleep set to 15 minutes.
