deviceAddress :: Device -> HostAddress Source #
deviceFromAddress :: (Word8, Word8, Word8, Word8) -> Device Source #
>>>deviceFromAddress (192, 168, 0, 1)192.168.0.1
If we know the IP address of a Device, we can create it directly, rather than calling discoverDevices.
A message we can send to a Device. r is the type of the expected response.

Methods
liftProductLookupError :: ProductLookupError -> MonadLifxError m Source #
lifxThrow :: MonadLifxError m -> m a Source #
sendMessage :: Device -> Message r -> m r Source #
Send a message and wait for a response.
broadcastMessage :: Message r -> m [(Device, r)] Source #
Broadcast a message and wait for responses.
discoverDevices :: Maybe Int -> m [Device] Source #
Search for devices on the local network. If an integer argument is given, wait until we have found that number of devices - otherwise just keep waiting until timeout.
Instances
sendMessageAndWait :: (MonadLifx m, MonadIO m) => Device -> Message () -> m () Source #
Like sendMessage, but for messages whose effect is not instantaneous (e.g. SetColor),
block (using threadDelay) until completion.

Message encoding
These are used internally by LifxT's sendMessage and broadcastMessage.
They are exposed in order to support some advanced use cases.
