Build Status PyPI version

Simple Ruuvitag 🔧

Simple Ruuvitag is a hard frok and HEAVY simplification of ttu work ruuvitag-sensor

It uses bleson python lib, which leverages Python 3 native support for Bluetooth sockets. However, in order for python to have access to AF_SOCKET family, python needs to be compiled with lib-bluetooth or bluez.

⚠️ This is a recent library with no guarantee of stability. There might be breaking changes so use the release tags to pull specific version

Installation

pip install simple-ruuvitag

Usage

Simplest usage

Simplest usage is using ruuvi_client internal state. The client will keep the latest state of all sensors that have been polled.

from simple_ruuvitag import RuuviTagClient
macs = ['CC:2C:6A:1E:59:3D', 'DD:2C:6A:1E:59:3D']
ruuvi_client = RuuviTagClient(mac_addresses=macs)
ruuvi_client.start()

last_datas = ruuvi_client.get_current_datas()
print(last_datas)

However this means that if a sensor doesn't get updated in a while, the state will contain old data that might pollute your dataset. To clear the state use the flag consume=True

last_datas = ruuvi_client.get_current_datas(consume=True)

Callback usage

You cal also use a callback to handle data as it is recieved by the library. Just pass a callback parameter to the listen method

from simple_ruuvitag import RuuviTagClient
def handle_callback(mac_address, data):
	print(f"Data from {mac_address}: {data}")

macs = ['CC:2C:6A:1E:59:3D', 'DD:2C:6A:1E:59:3D']
ruuvi_client = RuuviTagClient(callback=handle_callback, mac_addresses=macs)
ruuvi_client.start()

Continous use:

Although the bluetooth observer is running, data might stop coming through due to duplication removal in bleson. This issue is fixed in TheCellule/python-bleson#40 and in simple-ruuvitag v0.0.6

If you still find this issue, simple-ruuvitag has a method for to re-scan:ruuvi_client.rescan() which will restart the observer, and data should start flowing again.

ruuvi_client.start()
time.sleep(5)
last_datas = ruuvi_client.get_current_datas()
print(last_datas)
ruuvi_client.rescan()
time.sleep(5)
last_datas = ruuvi_client.get_current_datas()
print(last_datas)
time.sleep(5)

Change monitored devices on the fly

from simple_ruuvitag import RuuviTagClient
def handle_callback(mac_address, data):
	print(f"Data from {mac_address}: {data}")

macs = ['CC:2C:6A:1E:59:3D', 'DD:2C:6A:1E:59:3D']
ruuvi_client = RuuviTagClient(callback=handle_callback, mac_addresses=macs)
ruuvi_client.start()

new_macs = ['CC:2C:6A:1E:59:3D']
ruuvi_client.set_mac_addresses(new_macs)

AttributeError: module 'socket' has no attribute 'AF_BLUETOOTH'

  1. Install bluez or lib-bluetooth depending on your platform
  2. Rebuild python.
