RuuviTag Sensor is a Python library for communicating with RuuviTag BLE Sensor Beacon and for decoding sensord data from broadcasted eddystone-url.
- RuuviTag with Weather Station firmware
- Setup guide
- Supports Data Format 2, 3, 4 and 5
- Python 2.7 and 3
- psutil
- Package uses psutil to start and stop processes. Psutil requires
sudo apt-get install python-dev python-psutilorsudo apt-get install python3-dev python3-psutil
- Package uses psutil to start and stop processes. Psutil requires
- psutil
- Linux
- Package's Windows and OSX supports are only for testing and url decoding
- Bluez
sudo apt-get install bluez bluez-hcidump- Package uses internally hciconfig, hcitool and hcidump. These tools are deprecated. In case tools are missing, older version of Bluez is required (Issue)
- Superuser rights
- BlueZ tools require superuser rights

RuuviTag sensors can be identified using MAC addresses.
from ruuvitag_sensor.ruuvitag import RuuviTag
sensor = RuuviTag('AA:2C:6A:1E:59:3D')
# update state from the device
state = sensor.update()
# get latest state (does not get it from the device)
state = sensor.state
print(state)get_datas calls the callback every time when a RuuviTag sensor broadcasts data
from ruuvitag_sensor.ruuvi import RuuviTagSensor
def handle_data(found_data):
print('MAC ' + found_data[0])
print(found_data[1])
RuuviTagSensor.get_datas(handle_data)Optional list of macs and run flag can be passed to the get_datas function. Callback is called only for macs in the list and setting run flag to false will stop execution. If run flag is not passed, function will execute forever.
from ruuvitag_sensor.ruuvi import RuuviTagSensor, RunFlag
counter = 10
# RunFlag for stopping execution at desired time
run_flag = RunFlag()

# List of macs of sensors which will execute callback function
macs = ['AA:2C:6A:1E:59:3D', 'CC:2C:6A:1E:59:3D']
RuuviTagSensor.get_datas(handle_data, macs, run_flag)get_data_for_sensors will collect latest data from sensors for specified duration.
from ruuvitag_sensor.ruuvi import RuuviTagSensor
# List of macs of sensors which data will be collected
# If list is empty, data will be collected for all found sensors
macs = ['AA:2C:6A:1E:59:3D', 'CC:2C:6A:1E:59:3D']
# get_data_for_sensors will look data for the duration of timeout_in_sec
timeout_in_sec = 4
datas = RuuviTagSensor.get_data_for_sensors(macs, timeout_in_sec)
# Dictionary will have lates data for each sensor
print(datas['AA:2C:6A:1E:59:3D'])
print(datas['CC:2C:6A:1E:59:3D'])Reactive wrapper and background process for RuuviTagSensor get_datas. Optional MAC address list can be passed on initializer and execution can be stopped with stop function.

find_ruuvitags function will exeute forever and when new RuuviTag sensor is found it will print it's MAC address and state at that moment. This function can be used with a command line applications. Logging must be enabled and set to print to console.

- 1st is Data Format 2 so identifier is None as sensor doesn't broadcast any identifier data
- 2nd is Data Format 4 and it has an identifier character

Unit tests use unittest.mock library, so Python 3.3. or newer is required.
Run with nosetests
$ pip install nose
$ nosetestsRun with setup
$ python setup.py testVerification test sciprt executes a set of tests on active RuuviTags. Tests require at least one active RuuviTag and Python 2.7 and 3.x.
$ chmod +x verification.sh
$ ./verification.shExamples are in examples directory, e.g.
- Keep track of each sensors current status and send updated data to server. Sync and async version.
- Send found sensor data to InfluxDB. Reactive and non-reactive version.
- Simple HTTP Server for serving found sensor data. Flask, aiohttp and aiohttp with Rx.
