Python interface to control KEF speakers

Supported: KEF LS50 Wireless (Requires firmware June 2018 or later)

Untested: KEF LSX

Features supported

• Get and set volume
• Mute and Unmute
• Get and set source input
• Get if the speakers are online
• Automatically connects and disconnects when speakers goes online/offline
• Turn off speaker

Features unfortunatly unsupported

• Turn on is impossible over tcp/ip because the speaker turns off network interface when turned off. This is true for LS50 Wireless. LSX should be possible to turn on.

Note: One workaround to turning on is to use IR commands to turn on. I have included a lirc config with all the keys on the remote. Note that each command has to be sent twice to work (at least for me).

Install

pip install pykef

Examples

Setup:

host = '192.168.1.200'
port = 50001
speaker = KefSpeaker(host, port)

Set volume:

speaker.volume = 0.5 # %50 vol

Get volume:

volume = speaker.volume

Set source:

speaker.source = InputSource.AUX

Get source:

source = speaker.source

Mute:

speaker.volume = None
# Or
speaker.muted = True

Unmute (set to volume before mute):

speaker.muted = False

Step volume up

speaker.increseVolume() # 5% increase
speaker.increseVolume(0.10) # 10% increase

Step volume down

speaker.decreaseVolume() # 5% increase
speaker.decreaseVolume(0.10) # 10% increase

Turn off

speaker.turnOff()
