GL521MG working with the device for the first time

Good Afternoon.
Someone has worked with the GL521MG that can help me on what sensor can i add to the device
Also some questions, this device has an ignition sensor (or vitual ignition) parameter
Also im working with the temperature sensor "WTH301", ive already activated the bluetooh option on the device (picture 1), and the other section with the MAC of the temperature sensor (pictures 2 and 3). my question is how do i know if the device has conected to the temperature sensor or viceversa, and what parameter im gonna get in the platform indicating the external temperature from the temp sensor.

Thank you, any help is appreciated.
