This project automates "Becker Antriebe" shutter also known as CC31/CC51 using the Centronic USB Stick V2

./centronic-stick.py [-hlst] [--checksum <code>] [--device <device>] [--add <modifier>] [--mod <modifier>] [--remove <code>] [--send <UP|UP2|DOWN|DOWN2|HALT|DOWN:<delay>|UP:<delay>|CLEARPOS|TRAIN|TRAINMASTER|REMOVE> --channel <[unit:]channel>]

This script is used send command codes to CC11/CC51 compatible receivers through the CentronicControl USB Stick
It is necessary to own such USB device and to PAIR it first, before using commands like UP and DOWN

                 -h: shows this help
                 -l: listen on the centronic USB device to fetch the codes
                 -s: display the current db stats (incl. last run of a unit)
                 -t: test mode - no codes will be send and no numbers consumed / works only with '--send'
   --send <command>: submit a completely generated code for UP/UP2/DOWN/DOWN2/HALT/DOWN:<delay>/UP:<DELAY>/CLEARPOS/TRAIN/REMOVE commands / requires '--channel'
                     While UP2 and DOWN2 are the intermediate position (E.g. sun protection)
  --device <device>: set the device if it differs from the default, also host:port possible (ser2net)
--channel <[unit:]channel>: define the unit (1-5) and channel (1-7) being used for '--send'. Example: 2:15 will close shutter for unit 2 on all channels
  --checksum <code>: add a checksum to the given 40 char code and output (without STX, ETX)
   --mod <modifier>: used to manipulate the db entries
   --add <modifier>: used to add a db entry
    --remove <code>: used to remove an entry from db

INSTALLATION

Run the install.sh script to install all necessary dependencies. The installer will also configure sudo to allow FHEM the execution of centronic-stick.py.

For those who are familar with the installation routine, the following steps are required

• Install python3 pip
• Install python3 module pyserial using python3 pip
• Add fhem user into sudoers file to allow executing centronic-stick.py from the FHEM website

PROGRAM RECEIVER

To make recievers listening to the Centronic USB Stick, the "master sender" is required to add additional senders. The "master sender" can either be the wall-mounted transmitter or a remote.

To program another sender, please follow the below instruction

1) Press and hold the programming button on the MASTER SENDER for ~3 seconds The receiver should confirm with a single "Klack" noise

2) Run the below command to TRAIN the receiver The receiver should confirm with a single "Klack" noise followed by a "Klack - Klack" once the training succeeded

./centronic-stick.py --send TRAIN --channel 1

Repeat the steps for all the receivers using different channels (E.g. --channel 2, --channel 3, [...])

You have successfully paired the Centronic Stick with your shutter(s)

ADD MORE CHANNELS

By default the --channel argument uses the first known unit (registered in the database file) for a maximum of 7 channels.

If more channels are required, the --channel argument can be used to choose different units (maximum 5)

Example:

# program another unit on channel 1
./centronic-stick.py --send TRAIN --channel 2:1

# program a third unit on channel 7
./centronic-stick.py --send TRAIN --channel 3:7

EXAMPLE USAGE

To move down the shutter, run the below command (amend the channel if neccessary)

# move down the shutter programmed on channel 1 for unit 1
./centronic-stick.py --send DOWN --channel 1

To move up the shutter on unit 2 and channel, run the below command

# move up the shutter programmed on channel 1 for unit 2
./centronic-stick.py --send UP --channel 2:1

To pause the movement on unit 3 and channel 1 (which is not the same as unit 1 and channel 1), run the command

# stop shutter on unit 3 channel 1
./centronic-stick.py --send HALT --channel 3:1

To move down all shutters per explicit unit, run the below command

# --channel 15 and --channel 1:15 is the same
./centronic-stick.py --send HALT --channel 1:15

To move down all shutters on ALL configured units, run the below command (check -s argument to see which unit is configured)

# move down shutter on all configured units and all channels (15 = broadcast)
./centronic-stick.py --send DOWN --channel 0:15

REMOVE SENDER

To unpair the centronic-stick.py the following steps can be achieved

1) Press and hold the programming button on the MASTER SENDER for 3 seconds The receiver should confirm with a single "Klack" noise

2) Run the below commands to REMOVE the sender from its receiver The receiver should confirm with a single "Klack" noise followed by a "Klack - Klack"

# remove unit 1 with channel 1 from the shutter
./centronic-stick.py --send REMOVE --channel 1

*Please note that this command is per channel

Once ALL SENDERS for a specific unit are removed from ALL RECEIVERS it is safe to reset the increment counter using --mod argument.

DATABASE OUTPUT

Below is an example output of the sqlite3 database

code      increment configured  last run       
1737b     825       1           2020-04-01 17:26
1737c     0         0           (unknown)
1737d     0         0           (unknown)
1737e     0         0           (unknown)
1737f     0         0           (unknown)

TROUBLESHOOTING

Since this script requires to store the incremental numbers for any unit being configured, the database file centronic-stick.db is used. It might be necessary to manually change or increase the number to match with the receiver.

Use the argument --mod "<unit>:<increment>:<configured>" (CAREFULLY) to set the unit properties
