1. Description
The Tabs Door & Window sensor utilizes
LoRaWAN connectivity to communicate the
proximity or not of a magnet. The intended
use is to place the sensor and magnet on
separate elements of a door or window to
determine if the door or window is open or
closed.
The sensor is composed of two parts. The
main body contains the active electronics to
measure magnetic fields and transmit any
changes to a LoRaWAN network. The second
part is a permanent magnet of sucient field
strength to be detected by the Hall Eect
sensor on the main body.

3. Operation
3.1 Power On Reset
Anytime the device power drops below 2.8V the device will enter a Power
On Reset (POR) when greater than 2.8V is restored. After a POR the device
will wait up to 30 seconds before entering default operation.
3.2 Transport Mode
They are shipped with a plastic battery isolation tab that must be removed
to enable operation.
3.3 Installation Mode
The device shall enter installation mode after being commanded by the
network and remain in installation mode for 3 minutes. While in installation
mode the device will flash the LED 3 times within 500ms for every transition
between sensing states, i.e. whenever the device detects changes between
open and closed.
3.4 Default Operation
While in default operation the device will immediately send a message any
time there is a transition from Open to Close or vice-versa. Additionally, the
device will send a message anytime it has been inactive for 6 hours.

4.1 Status
4.1.1 Common Fields
Status[7:0]
{Fault3, Fault2, LED1, LED0, Fault1, Fault0, BTN1, BTN0}
• Nominally Fault0 indicates no network time available
• Nominally Fault1 indicates loss of primary sensor function
• Nominally Fault2 indicates loss of secondary sensor function
• Nominally Fault3 indicates loss of network connectivity
Battery[7:0]
LoRaWAN Decode
• 0 => Device is charging or line powered
• 1 to 254 => device level, 1 = minimum and 254 = fully charged
• Futher encode
• [7:4] = predicted battery life percentage, 15 = New, 0 = Replace
• [3:0] = BatteryVoltage — 2.5V, in 0.1V steps, So 3.1V = 6
• 255 => Device could not measure battery — possible Fault
Temperature[6:0]
Unsigned Integer (0 to 127) Temperature = value - 32, measurement range -32° to 95°C
