You will be able to get the MAC address from the data packet sent by the tag.

The packet breakdown can be found at:

ruuvi/ruuvi-sensor-protocols/blob/master/dataformat_05.md

## Data Format 5 Protocol Specification (RAWv2)
*Lifecycle: Beta testing* 

The data is decoded from "Manufacturer Specific Data" -field, for more details please check [this article](http://www.argenox.com/a-ble-advertising-primer/) out.
Manufacturer ID is 0x0499. 
The actual data payload is: 

Offset | Allowed values | Description
-------|:--------------:|-----------
0      | `5`            | Data format (8bit)
1-2    | `-32767 ... 32767` |Temperature in 0.005 degrees
3-4    | `0 ... 40 000`  | Humidity (16bit unsigned) in 0.0025% (0-163.83% range, though realistically 0-100%)
5-6    | `0 ... 65534` |   Pressure (16bit unsigned) in 1 Pa units, with offset of -50 000 Pa
7-8    | `-32767 ... 32767`  | Acceleration-X (Most Significant Byte first)
9-10   | `-32767 ... 32767`  | Acceleration-Y (Most Significant Byte first)
11-12  | `-32767 ... 32767`  | Acceleration-Z (Most Significant Byte first)
13-14  | `0 ... 2046`, `0 ... 30` | Power info (11+5bit unsigned), first 11 bits is the battery voltage above 1.6V, in millivolts (1.6V to 3.646V range). Last 5 bits unsigned are the TX power above -40dBm, in 2dBm steps. (-40dBm to +20dBm range)
15     | `0 ... 254`| Movement counter (8 bit unsigned), incremented by motion detection interrupts from accelerometer
16-17  | `0 ... 65534`| Measurement sequence number (16 bit unsigned), each time a measurement is taken, this is incremented by one, used for measurement de-duplication. Depending on the transmit interval, multiple packets with the same measurements can be sent, and there may be measurements that never were sent.
18-23  | `Any valid mac` | 48bit MAC address.
