WTS Temperature sensor
13 / 32
External Temperature (Temp_PT100): 2 bytes ( For model WTS-11 only)
 Temperature: 0x0ABB/100=27.47℃
 Temperature: (0xF5C6-65536)/100=-26.18℃
In WTS-10, WTS-12, these 2 bytes are always 00 00
Open Duration & Open Timeout Alarm: 2 bytes ( For model WTS-12 only)
Bits 15 14 [13:0]
Value: Reserve Timeout Alarm Bright Duration
 Timeout Alarm: This bit indicates if the bright detection exceeds certain time. The default
timeout is 5 minutes. If bright duration exceed timeout, WTS-12 will set this bit to 1 and
immediately send an uplink packet as an Alarm.
0: Bright detection duration within timeout
1: Bright detection duration exceed timeout
This feature can be used to monitor if the fridge has been open for long time and provide an
alarm.
 Bright Duration: total 14 bits Shows the current / last bright duration.
Unit: second. range: 0 ~ 16383 Seconds (max ~ 4.5 hours)
 If current light detection state is dark, the bright duration shows last bright duration.
 If current light detection state is bright, the bright duration shows current bright duration.
In WTS-10, WTS-11, these 2 bytes are always 00 00
