Prerequisites

Note:
This module does not replace the initial commissioning of the Warema WMS network by a specialist company.

To use this module you need:

• A completely installed Warema WMS network
• Warema "WMS Hand-held transmitter"
• Warema "WMS Stick"
• Warema "WMS Receiver" (i.e. "WMS Plug receiver" or "WMS Actuator UP")

Optional devices (not needed for proper operation):

• "WMS Weather station eco (receiving weather data is alpha status)"
• "WMS Weather station plus (receiving weather data is alpha status)"
• "WMS WebControl"
• "WMS Central transmitter"
• "WMS studio software"

Limitations and known issues

• Not all device types of Warema WMS are supported. See Features.
• Weather station and time broadcast are alpha state. Since I don't own the devices only mocking tests were possible.

Features

Supported Warema WMS device types

• 02: WMS Stick/ WMS Software
• 06: Weather station (alpha status)
• 07: Remote control (+)
• 20: Plug receiver
• 21: Actuator UP
• 25: Radio motor
• 2E: Actuator 230 V UP
• 63: Web control

WMS network configuration

• Listing serial ports with WMS Stick ("WMS Stick" required connected to USB Port): listWmsStickSerialPorts()
• Getting WMS network paramters (WMS remote control ruquired, e. g. "WMS Hand-held transmitter"): WmsVbStickUsb( testComName, 17/*channel*/, "FFFF"/*panid*/, "00112233445566778899AABBCCDDEEFF"/*key*/, {} /*options*/, testCallback );
• Discover the devices contained in the WMS network: scanDevices()

controlling venetian blinds

• Getting current blind position (heigth and angle of slats)
• Moving down
• Moving up
• Tilt slats down
• Tilt slats up
• Moving to a specified position (heigth and angle of slats)
• Stop moving blinds
• Wave request for blinds

Installation

After the installation of the npm package you may have to determine the parameters of the WMS network.

You also need to know the serial numbers of the devices you want to control. The serial numbers are printed on labels on the Warema WMS devices. If you do not have access to the printed serial numbers, you can scan the devices on the network with the function 'scanDevices()'. You can identify individual blinds with the function vnBlindWaveRequest( serialNo ).

See the examples below.

Starting getting network parameters...
- Open the battery case of the WMS Handheld transmitter.
- Select the channel using the (+) button.
  Notice: If an unassigned channel is selected, press the (+) button for 5 s.
          As soon as the LED flashes, all channels can be selected by
          pressing the (+) button again
- Press the learn button in the battery case of the WMS Handheld
  transmitter for approx. 5 s. LEDS go green; the transmission LED flashes.
  For several seconds, the WMSHand-held transmitter plus scans the operating 
  range for devices.
- Each time when scanning stops with red LED perform steps:
  1)  When you press the control button (A), you can check WHICH target device
      was just found.
  2) If you can *not* see the output
       "*** Waving and Hello!"
     on the screen after pressing (A) another device than the WMS Stick has
     been found. Press the (C) button to switch to the next receiver.
  3) If you can see the output
       "*** Waving and Hello!"
     on the screen after pressing (A) then the WMS Stick has been found. 
     Press the STOP button to assign the WMS Stick to the channel. After 
     pressing STOP the network parameters are displayed on the screen. 
- Press Ctrl-C to abort.

API documentation

Static Methods

WmsVbStickUsb.listWmsStickSerialPorts( callback(error,data) )

Lists WMS Sticks connected to serial ports. I.e. all serial ports responding on WMS command {V} (WMS Stick version number).

Sample output:

[
  {
    "manufacturer": "FTDI",
    "serialNumber": "A5003TQL",
    "pnpId": "usb-FTDI_FT232R_USB_UART_A5003TQL-if00-port0",
    "vendorId": "0403",
    "productId": "6001",
    "path": "/dev/ttyUSB0",
    "wmsStickVersion": 37605107
  }
]

The function has a timeout of 1 second. It is normal for the timeout to occur. The function opens all serial ports and tries to determine the version of the WMS stick. If a port can be opened and it is not a WMS stick, the port does not respond and the search ends with the timeout.

Tip: Linux permissions for /dev/ttyUSBn
When running warema-wms-venetian-blinds as a normal user you may be unable to access the WAREMA Stick with error message Permission denied, cannot open /dev/ttyUSB0 .The device is most likely attached to user group 'dialout'.

ls -l /dev/ttyUSB0
crw-rw---- 1 root dialout 188, 0 Jun 14 20:36 /dev/ttyUSB0

Just add your user to the dialout group so you have appropriate permissions on the device.

sudo usermod -a -G dialout $USER

(You may need to logout and back in or even to reboot for the new group to take effect.)

Class WmsVbStickUsb

Constructor WmsVbStickUsb( portPath, channel, panid, key, options, callback )

Use this constructor to create a new WMS Stick.

Parameters:

• portPath
  Name of serial interface, for example /dev/ttyUSB0
• channel
  WMS network channel (see detectNetworkKeys())

• key
  WMS network key (see detectNetworkKeys())
• options
  Up to now there are no options defined for the WMS Stick.
• callback function( err, msg )
  Callback function. All events emitting data result in an call of the callback function. Parameter msg is an javascript object containing the two properties topic and payload. In case of error the err parameter contains a string describing the error.

    {
      "topic": "<topic indication type of event>",
      "payload": "<Data to topic>",

wmsStick.setWatchMovingBlindsInterval(intervalMsec)

The function sets the interval at which the position of the blinds is read for all blinds detected as moving. In the specified interval the function vnBlindGetPosition() is automatically executed for each blind until not moving any more. If you omit the interval or set it to less than 100 msec, the automatic update of the position is disabled.

Parameters:

• intervalMsec
  Interval for watching current blind position in milliseconds.

Callback messages:

• Topic wms-vb-blind-position-update
  This message is emitted when a blind position/angle changes.

wmsStick.setCmdConfirmationNotificationEnabled(boolean)

Enabling/disabling callback messages "wms-vb-cmd-result-set-position" and "wms-vb-cmd-result-stop". By default they are disabled.

Parameters:

• boolean
  If parameter evaluates to true the callcacks for command confirmations are enabled.

wmsStick.vnBlindSetPosition(blindId,position,angle)

Moves the venetian blind to the desired position

Parameters:

• blindId
  This parameter may be the snr, the snrHex or the name of a venetian blind.
• position
  Level of the blind in percent from 0 to 100. At position 0 the blind is completely opened. Set the angle to -100 to completely retract the blind into the cover. At position 100 the blind is fully closed.
• angle
  Angle of the blind's slats in percent from -100 to 100. At angle -100 the slats are completely inclined inwards. At angle 0 the slats are in horizontal position. At angle 100 the slats are completely inclined outwards.

Callback messages:

• Topic wms-vb-cmd-result-set-position
  Confirmation of command.
• Topic wms-vb-blind-position-update
  This message is emitted together with the command's successful confirmation when the position/angle of the blind changes.

wmsStick.vnBlindSlatUp(blindId)

The slats tilt up. (The angle is decreased to the next position.)
