Python library for interfacing with Motion Blinds
This library allows you to control Motion Blinds from Coulisse B.V. This library is primarly writen to be used with HomeAssistant but can also be used stand alone.
For products see https://motion-blinds.com or https://coulisse.com/products/motion.

Installation
Use pip:
$ pip install motionblinds
or
$ pip install --use-wheel motionblinds
Retrieving Key
The Motion Blinds API uses a 16 character key that can be retrieved from the official "Motion Blinds" app for Ios or Android. Open the app, click the 3 dots in the top right corner, go to "settings", go to "Motion APP About", Please quickly tap this "Motion APP About" page 5 times, a popup will apear that gives you the key.
Please note that "-" characters need to be included in the key when providing it to this library. The key needs to be simular to "12ab345c-d67e-8f"
Usage
For creation of a device you could use the following lines of codes (using a correct IP of the gateway and Key retrieved from the App)
from motionblinds import MotionGateway
m = MotionGateway(ip = "192.168.1.100", key = "12ab345c-d67e-8f")
This library is not polling. Thus you need to populate the connected blinds using the GetDeviceList method and update device information using the Update method. Note that multicast pushes from the gateway can be processed to retrieve instant status updates (see Multicast pushes section)
m.GetDeviceList()
m.Update()
Note that GetDeviceList needs to be run before using Update since the device_type, mac and token are retrieved using the GetDeviceList method. Once the connected blinds are discoverd using the GetDeviceList method, they can be listed by the device_list property:
m.device_list
This will return a dict with as key the mac_adress of the blind and as value a MotionBlind device that can be used to retreive information of that blind and control that blind.
Some example code that will print the information of the gateway and all conected blinds:
>>> from motionblinds import MotionGateway
>>> m = MotionGateway(ip = "192.168.1.100", key = "12ab345c-d67e-8f")
>>> m.GetDeviceList()
{'abcdefghujkl0001': <MotionBlind mac: abcdefghujkl0001, type: None, status: None, position: None %, angle: None, limit: None, battery: None, RSSI: None dBm>}
>>> m.Update()
>>> print(m)
<MotionGateway ip: 192.168.1.100, mac: abcdefghujkl, protocol: 0.9, N_devices: 1, status: Working, RSSI: -71 dBm>
>>> for blind in m.device_list.values():
>>> blind.Update()
>>> print(blind)
<MotionBlind mac: abcdefghujkl0001, type: RollerBlind, status: Stopped, position: 0 %, angle: 0, limit: Limits, battery: 1195, RSSI: -82 dBm>
To open a blind the following example code can be used:
>>> from motionblinds import MotionGateway
>>> m = MotionGateway(ip = "192.168.1.100", key = "12ab345c-d67e-8f")
>>> m.GetDeviceList()
>>> m.Update()
>>> blind_1 = list(m.device_list.values())[0]
>>> blind_1.Update()
>>> blind_1.Open()
Instead of blind_1.Open() you can also use blind_1.Close(), blind_1.Stop(), blind_1.Set_position(50) or blind_1.Set_angle(90)
Multicast pushes
This library allows to listen for multicast pushes from the gateway in a parallel thread and process these pushes to get instant updates of the gateway and connected blinds status. To use this parallel pushes processing a MotionMulticast class object needs to be initilized. The MotionMulticast.Start_listen() and MotionMulticast.Stop_listen() can then be used to start and stop the parallel thread that is listening for incoming pushes. The MotionMulticast class object can be supplied to the MotionGateway class to let it update that gateway and its connected blinds. Externall callbacks can be registered for both gateway devices and blind devices (see tables below) An example code to listen for pushes for 30 seconds and print out gateway or blind information when a push comes in (when a blind finishes moving):
import time
from motionblinds import MotionMulticast, MotionGateway
def callback_func_gateway():
print(m)
def callback_func_blind():
for blind in m.device_list.values():
print(blind)
motion_multicast = MotionMulticast()
motion_multicast.Start_listen()
m = MotionGateway(ip="192.168.1.100", key="12ab345c-d67e-8f", multicast = motion_multicast)
m.GetDeviceList()
m.Update()
m.Register_callback("1", callback_func_gateway)
for blind in m.device_list.values():
blind.Register_callback("1", callback_func_blind)
time.sleep(30)
motion_multicast.Stop_listen()
Discovery
Motion Gateways can be discovered on your network using the MotionDiscovery class. The following example will try to discover gateways for 10 seconds and then print a dict containg the gateways and their connected blinds that were discovered.
>>> from motionblinds import MotionDiscovery
>>> d = MotionDiscovery()
>>> motion_gateways = d.discover()
>>> print(motion_gateways)
