aiolifx is a Python 3/asyncio library to control Lifx LED lightbulbs over your LAN.
Most of it was taken from Meghan Clarkk lifxlan package (https://github.com/mclarkk) and adapted to Python 3 (and asyncio obviously)
We are on PyPi so
pip3 install aiolifx
or python3 -m pip install aiolifx
After installation, the utility
aiolifx
can be used to test/control devices.
NOTE: When installing with Python 3.4, the installation produce an error message (syntax error). This can be safely ignored.
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()
discovery = alix.LifxDiscovery(loop, MyBulbs)
try:
loop.add_reader(sys.stdin, readin)
discovery.start()
loop.run_forever()
except:
pass
finally:
discovery.cleanup()
loop.remove_reader(sys.stdin)
loop.close()
Other things worth noting:
- Whilst LifxDiscovery 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 LifxDiscovery. 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
Run this command each time you make changes to the project. It enters at __main__.py
