Hello @rainer s, I have a Centronic EC545 Becker remote control. Do you know which encryption algorithm this remote uses?
According to their webpage it is a centronic remote control: EC545
Do you have any information about which encryption algorithm the info Centronic remote control uses ?
I donāt know the details about the encryption algorithm. But you will find further information here:
Hope this helps.
Thank you,now is working 
I need to move my Home Assistant server to another location. Therefore I try to connect my Becker stick remotely to my HA instance. I was thinking about using a raspberry pi or a thin client with a USB/IP or ser2net server on it. Has anyone tried this kind of configuration and give me some hints?
I use a full HA āslaveā instance on my Raspberry. I connected also my other wireless stick with Zigbee to this. For connection between HA āmasterā and"slave" I use Remote Home Assistant. This works perfect without any noticeable delay.
I disabled almost everything in the recorder within HA āslaveā to avoid any problems with SD cards. All devices are available in HA āmasterā and recorded there anyway.
The HA master is on a virtual machine running on a small server.
This setup is stable without any issues. Mostly itās running several months before I update and reboot.
Thank you very much. This looks like a very sensible and reliable solution. I am surprised that I have not come across this before.
Hi everyone,
first of all, thank you very much for all the work that is being done here and made available to everyone.
Iām fairly new to the HA world and my programming skills are a little rusty. Iām stuck at an earlier stage and wanted to ask for some advice: When adding the integration, it asks for a āDevice IPā ā what should I enter here? I took the information from the āBecker CentralControl HASā page and entered āhttp://$CENTRAL_CONTROL_IP_ADR/cgi-bin/cc51rpc.cgi.ā I suspect I need to adapt this to my local situation. Sorry for the noob question. Iāve been stuck on this for quite a while now.
Just to add a few more information: HA is hosted as own OS on a HA Yellow. Centronic USB with number 4035 200 041 0 is already connected to this stage. And I also adapted the configuration.yaml.
Thanks
Can you post a screenshot? For me I donāt think it asked for an IP rather the device path
You have to edit the configuration yaml file as mentioned in the readme.
The old-school way 
Thanks for the quick responses. I managed to do itāthe other integration led me in the wrong direction.
Hi,
I have a problem with the file ācentronic-stick.dbā. Home Assistant always writes into it:
āutf-8ā codec canāt decode byte 0x82 in position 98: invalid start byteā.
The pybecker integration is unable to correctly create the database file. It tries to write data to it in the wrong format. I tried deleting the file to let it recreate it on its own, I also tried creating an empty file, but the result is always the same.
Iām using a Becker USB stick Centronics and a Raspberry Pi 5 with 8GB RAM.
/dev/serial/by-id/usb-Becker-Antriebe_GmbH_CDC_RS232_v125_Centronic-if00
Thanks in advance for your advice.

The error wasnāt in the file but in the wrong USB stick path. Thanks, Ales"
Hi,
Iām using this integration for about 7 months and it works very good. Iāve connected 3 shutter via the Centronic stick ā4035 000 041 0ā.
But Iāve noticed that 1 of my 3 shutter is always loosing connection. I actually donāt know why. The distance between the shutter and the stick canāt be the problem.
After pairing (and repairing) I can control the shutter for days or weeks. I havenāt found any pattern by now. The log doesnāt show any errors. There is no difference between the working and the not working state. Do you have any ideas what I could try?
Iāve paired the shutter again an hour ago.

Since a while when I look into the HA integrations the icon of the Becker integration is not shown. On the place where the icon should appear it shows āIcon not availableā.
Is this something I can fix myself or can it be fixed?
Another thing I see in my configuration.yaml is this:
Device ā/dev/ttyACM0ā does not exist in your Home Assistant instance
But everything seems to be working fine, it is just annoying to see this message. Not sure when it exactly occurred. It could be any type of update (HAos, Proxmox, HA supervisor or core).
I have HAos running in Proxmox.
Is there a simple fix for this?
Hi, I have created a custom integration that works with the new Centronic Plus USB stick.
Chekc this out: [Custom Component] Integrate Becker Centronic Plus shutter motors into Home Assistant using the Centronic Plus USB stick
Hi everyone,
I had everything set up and running until a few days ago.
Now, the cover just won't react anymore. Log entries look like everything is working fine, i.e. I see the commands going out.
Cover works fine with the master remote.
What I do notice is that when I press the keys on the remote, I do NOT see anything in the logs. I understand that I am supposed to see something.
When trying to (re)pair the USB stick and the cover nothing seems to be happening. Again, I can see the commands going out in the logs but I get no "click" from the cover (which I do get when I set it to pairing mode using the master remote).
The evidence points to the stick being broken. Is there any way I can check if the stick is, in fact, broken?
