aiolifxc 0.5.1

Installation

We are on PyPi so:

pip3 install aiolifx

or:

python3 -m pip install aiolifx

NOTE: When installing with Python 3.4, the installation produce an error message

(syntax error). This can be safely ignored.

How to use

Essentially, you create an object with at least 2 methods:

• register

• unregister

You then start the LifxDiscovery task in asyncio. It will register any new light it finds. All the method communicating with the bulb can be passed a callback function to react to the bulb response. The callback should take 2 parameters:

• a light object

• the response message

The easiest way is to look at the file in the examples directory. “Wifi” and “Uptime” use a callback to print the info when it is returned.

In essence, the test program is this:

class bulbs():
""" A simple class with a register and  unregister methods
"""
    def __init__(self):
        self.bulbs=[]

    def register(self,bulb):
        self.bulbs.append(bulb)

    def unregister(self,bulb):
        idx=0
        for x in list([ y.mac_addr for y in self.bulbs]):
            if x == bulb.mac_addr:
                del(self.bulbs[idx])
                break
            idx+=1

def readin():
"""Reading from stdin and displaying menu"""

    selection = sys.stdin.readline().strip("\n")
    DoSomething()

MyBulbs= bulbs()
loop = aio.get_event_loop()
coro = loop.create_datagram_endpoint(
            partial(alix.LifxDiscovery,loop, MyBulbs), local_addr=('0.0.0.0', UDP_BROADCAST_PORT))
try:
    loop.add_reader(sys.stdin,readin)
    server = loop.create_task(coro)
    loop.run_forever()
except:
    pass
finally:
    server.cancel()
    loop.remove_reader(sys.stdin)
    loop.close()

Other things worth noting:

• Whilst LifxDiscover uses UDP broadcast, the bulbs are connected with Unicast UDP

• The socket connecting to a bulb is not closed unless the bulb is deemed to have gone the way of the Dodo. I’ve been using that for days with no problem

• You can select to used IPv6 connection to the bulbs by passing an IPv6 prefix to LifxDiscover. It’s only been tried with /64 prefix. If you want to use a /48 prefix, add “:” (colon) at the end of the prefix and pray. (This means 2 colons at the end!)

• I only have Original 1000, so I could not test with other types of bulbs

• Unlike in lifxlan, set_waveform takes a dictionary with the right keys instead of all those parameters
