PyBLNET 0.9.2

Automate wireless communication to UVR1611 via BL-NET

PyBLNET - a very basic python BL-NET bridge

A package that connects to the BL-NET that is connected itself to a UVR1611 device by Technische Alternative. It is able to read digital and analog values as well as to set switches to ON/OFF/AUTO.

Documentation on the modules and their methods can be found with the methods and modules themselves.

Two interfaces to BLNet exist and both are supported:

• Webinterface - Class BLnetWeb
• BLNet-Direct protocol [1] - Class BLNETDirect

However, as of now, there is no testing on the BLNet-Direct protocol of any kind, so enabling it is discouraged until the interface is fixed. Parsing the data via the web interface is the preferred way of accessing the BLNet for now.

The class BLNET is a wrapper around the two classes. When initializing the class, the two interfaces can be activated/deactivated. BLNetDirect provides 'analog', 'digital', 'speed', 'energy', 'power', whereas BLnetWeb supports 'analog' and 'digital' only. If both are active, BLNetDirect has priority. Setting switches and reading their manual/auto state is only possible via the BLNetWeb interface.

Usage

from pyblnet import test_blnet, BLNET, BLNETWeb, BLNETDirect

ip = '192.168.178.10'

# Check if there is a blnet at given address
test_blnet(ip) # -> True/False

# Convenient high level interface
blnet = BLNET(ip, password='pass', timeout=5)

# Control a switch by its ID
blnet.turn_on(10)
blnet.turn_auto(10)
blnet.turn_off(10)

# Fetch data (contains all available data using enabled interfaces)
print(blnet.fetch())



# The low level modules are also available
# note that the direct use of these modules is discouraged though

# Fetch the latest data via web interface
# Note that manual log in and log out are required
# when not using the with statement
with BLNETWeb(ip, password='pass', timeout=5) as blnet_session:
    print(blnet_session.read_analog_values())
    print(blnet_session.read_digital_values())

    # For publishing values
    blnet_session.set_digital_value('10', 'AUS')
    # Note that without explicit log out,
    # the BLNET will block any further web access for the next 150s
    # this is handled automatically when using the with statement

# Fetch data via the Protocol developed by TA
blnet = BLNETDirect(ip)
# Fetching the latest data
print(blnet.get_latest())
# Still inofficial because unexplicably failing often
print(blnet._get_data(1))
