Python code to interface HomeKit Accessories and Controllers

HomeKit Python

With this code it is possible to implement either a HomeKit Accessory or simulate a HomeKit Controller.

Limitations

• This code only works with HomeKit IP Accessories. no Bluetooth LE Accessories (yet)!
• No reaction to events whatsoever.

The code presented in this repository was created based on release R1 from 2017-06-07.

Installation

Use pip3 to install the package:

pip3 install --user homekit

HomeKit Accessory

This package helps in creating a custom HomeKit Accessory.

The demonstration uses this JSON in ~/.homekit/demoserver.json:

{
  "name": "DemoAccessory",
  "host_ip": "$YOUR IP",
  "host_port": 8080,
  "accessory_pairing_id": "12:00:00:00:00:00",
  "accessory_pin": "031-45-154",
  "peers": {},
  "unsuccessful_tries": 0,
  "c#": 0,
  "category": "Lightbulb"

}

Now let's spawn a simple light bulb accessory as demonstration:

#!/usr/bin/env python3

import os.path

from homekit import HomeKitServer
from homekit.model import Accessory, LightBulbService


if __name__ == '__main__':
    try:
        httpd = HomeKitServer(os.path.expanduser('~/.homekit/demoserver.json'))

        accessory = Accessory('Licht')
        lightService = LightBulbService()
        accessory.services.append(lightService)
        httpd.accessories.add_accessory(accessory)

        httpd.publish_device()
        print('published device and start serving')
        httpd.serve_forever()
    except KeyboardInterrupt:
        print('unpublish device')
        httpd.unpublish_device()

If everything went properly, you should be able to add this accessory to your home on your iOS device.

HomeKit Controller

The following tools help to access HomeKit Accessories.

discover.py

This tool will list all available HomeKit IP Accessories within the local network.

Usage:

python3 -m homekit.discover [-t ${TIMEOUT}]

The option -t specifies the timeout for the inquiry. This is optional and 10s are the default.

Output:

Name: smarthomebridge3._hap._tcp.local.
Url: http://192.168.178.21:51827
Configuration number (c#): 2
Feature Flags (ff): Paired (Flag: 0)
Device ID (id): 12:34:56:78:90:05
Model Name (md): Bridge
Protocol Version (pv): 1.0
State Number (s#): 1
Status Flags (sf): 0
Category Identifier (ci): Other (Id: 1)

Hints:

• Some devices like the Koogeek P1EU Plug need bluetooth to set up wireless before. Use your phone or the proper app to perform this
• paired devices should not show up

identify.py

#TODO rework after identify.py was converted to controller

This tool will use the Identify Routine of a HomeKit IP Accessory.

Usage:

python3 -m homekit.identify -d ${DEVICEID} 

Output:

Either identify succeeded. or identify failed followed by a reason (see table 5-12 page 80). One of the most common reasons is a already paired device.

pair.py

This tool will perform a pairing to a new accessory.

Usage:

python3 -m homekit.pair -d ${DEVICEID} -p ${SETUPCODE} -f ${PAIRINGDATAFILE} -a ${ALIAS} 

The option -d specifies the device id of the accessory to pair. Can be obtained via discovery.

The option -p specifies the HomeKit Setup Code. Can be obtained from the accessory.

The option -f specifies the file that contains the pairing data.

The option -a specifies the alias for the device.

The file with the pairing data will be required to for any additional commands to the accessory.

list_pairings.py

This tool will perform a query to list all pairings of an accessory.

Usage:

python3 -m homekit.list_pairings -f ${PAIRINGDATAFILE} -a ${ALIAS} 

The option -f specifies the file that contains the pairing data.

The option -a specifies the alias for the device.

This will print information for each controller that is paired with the accessory:

Pairing Id: 3d65d692-90bb-41c2-9bd0-2cb7a3a5dd18
        Public Key: 0xed93c78f80e7bc8bce4fb548f1a6681284f952d37ffcb439d21f7a96c87defaf
        Permissions: 1 (admin user)

The information contains the pairing id, the public key of the device and permissions of the controller.

unpair.py

This tool will remove a pairing from an accessory.

Usage:

python -m homekit.unpair -f ${PAIRINGDATAFILE} -a ${ALIAS}

The option -f specifies the file that contains the pairing data.

The option -a specifies the alias for the device.

get_accessories.py

This tool will read the accessory attribute database.

Usage:

python3 -m homekit.get_accessories -f ${PAIRINGDATAFILE} -a ${ALIAS} [-o {json,compact}]

The option -f specifies the file that contains the pairing data.

The option -a specifies the alias for the device.

The option -o specifies the format of the output:

• json displays the result as pretty printed JSON
• compact reformats the output to get more on one screen

get_characteristic.py

This tool will read values from one or more characteristics.

Usage:

python3 -m homekit.get_characteristic -f ${PAIRINGDATAFILE} -a ${ALIAS} -c ${Characteristics} [-m] [-p] [-t] [-e]

The option -f specifies the file that contains the pairing data.

The option -a specifies the alias for the device.

The option -c specifies the characteristics to read. The format is <aid>.<cid>. This option can be repeated to retrieve multiple characteristics with one call.

The option -m specifies if the meta data should be read as well.

The option -p specifies if the permissions should be read as well.

The option -t specifies if the type information should be read as well.

The option -e specifies if the event data should be read as well.

put_characteristic.py

This tool will write values to one characteristic.

Usage:

python3 -m homekit.put_characteristic -f ${PAIRINGDATAFILE} -c ${Characteristics} ${value}

The option -f specifies the file that contains the pairing data.

The option -c specifies the characteristics to change. The format is <aid>.<cid> <value>. This option can be repeated to change multiple characteristics with one call.

For example, this command turns of a Koogeek P1EU Plug:

python3 -m homekit.put_characteristic -f koogeek.json -c 1.8 false

get_events.py

This tool will register with an accessory and listen to the events send back from it.

Usage

python3 -m homekit.get_events -f ${PAIRINGDATAFILE} -c ${Characteristics} 

The option -f specifies the file that contains the pairing data.

The option -c specifies the characteristics to change. The format is <aid>.<cid>. This option can be repeated to listen to multiple characteristics with one call.

For example, you can listen to characteristics 1.8 (on characteristic), 1.22 (1 REALTIME_ENERGY) and 1.23 (2 CURRENT_HOUR_DATA) of the Koogeek P1EU Plug with:

python3 -m homekit.get_events -f koogeek.json -c 1.8 -c 1.22 -c 1.23

This results in

event for 1.8: True
event for 1.22: 6.0
event for 1.23: 0.01666
event for 1.22: 17.0
event for 1.23: 0.06388
event for 1.23: 0.11111
event for 1.22: 18.0
event for 1.23: 0.16111
event for 1.8: False
