Rademacher DuoFern

Hi e-raser

Here are some of the automation I have already realized with FHEM and Raspberrymatic, all windows have Homematic sensors:

  • all Rollos run on automatic mode, since they work slower and more silent than when a command is executed
  • on weekends or when we leave the windows open at nicht, rollos are set to manual mode, so that they don’t open automatically.
  • I have the sun sensor connected to some of the rollos. When the internal temperature is too high, and this is measured by Raspberrymatic, I enable the sun mode on Rollotron. Rollo won’t be closed when the sun shines and is cool inside.
  • when windows are tilted or open, detected by Homematic sensor, rasbperrymatic sends a command to activate the Ventilating Mode.

Except for the Sun sensor, I could do everything else with the Rollos in Manual mode, but they would run on the fast and loud setting.

I do all of that in HA, in manual mode. Slower and less noisy would be great, but it depends on the hardware I think. I use many 1200 which only have one „speed setting“.

I have the 1800 model, they have 3 speed settings and the difference in noise and speed is big

Do have one 1800 too. But decided that as I want to fully control them via HA the extra price for unneeded features (mainly display/local control features) is not worth to pay. In manual mode there‘s no difference except for the begin and end of an opening/closure where they slowly start/end the process.

Anyone else using Raspbarrymatic and pyduofern together?

It was working nice on HA, but since a couple of HA updates - I don’t know when exactly it stopped working - it seems there is a conflict between both USB Sticks.
When both are connected, Duofern doesnt work and Raspberrymatic response is slow and a lot of devices fail to communicate.
When Raspberrymatic is stopped and after restarting HA completly, pyduofern works fine, but if I start Raspberrymatic, then it’s over.

Hi all,

I am a very new user in HA ,switching over from fhem. I am using the DUOFERN Stick with some RolloTubes and I wanted to ask you where I can find the latest documentation how to implement the stick in HomeAssistant. Is there a HACS repository available?

Thanks for your reply,
Spartacus

Hi there,

I found the pyduofern in HACS and installed it. I a a little bit confused, because I need a 4 digit Hex-Code. In fhem I have installed a 6-digit Hex-Code for the RolloTube and this was the Code from the RolloTube.

Can I use this Code for my HA installation and everything works or do I have to pair my Tubes again?
Thanks,
Spartacus

I recommend looking at GitHub - gluap/pyduofern-hacs: Repository managing hacs-integration for pyduofern for this. @gluap is the maintainer and genius behind this great integration.

Hi ,

thanks for the hint, but I found it, as mentioned in my post before!

I have concerns about moving the stick to the new HA environment. Currently it runs in fhem and works fine and I don’t know how to transfer it to HA without re-pairing the tubes to the stick.

I am wondering about the documentation because my code in fhem is 6 digits and not 4 digits as stated in the manual. I also understand that I need to use the hex code printed on the tube and not a random 4 digit code. So I am a little confused. Can anyone support me?

  1. Possible similar topic: Rademacher changed pairing codes from 6 digits to 10 digts · Issue #31 · gluap/pyduofern · GitHub
  2. What’s the problem with re-pairing your devices once this integration is installed? If you don’t have dozens of devices it should really be fine for a single migration process. Usually takes 5 minutes per device strictly following the instructions.

Hi all,

i have tried to implement my DUOFERN Stick in HA, but it is not running. got an Error in the Log:
DUOFERN unknown msg: 0fff0f2c63005a1a110000000000ff49d5f2ffffff01
And in the Integrations Tab it looks like this:

anyone an idea?

The unknown message I received is a message from the tube. I saw it in fhem. It seems to b that I have to reset all the paired components and to start pairing again. Unknown therefore, because in fhem the Stick is confugured with 6 digits, which is currentley not supportet in HA. Therefore I think I cannot use the paired tube with HA, only if I will reset everything! This is what I want to avoid because the box of the tube is not easy to open.The risk is too high, that nothings runs later.

Are there any known limitations in terms of the maximum number of devices the DuoFern stick (and therefore this integration) is able to handle?

I read something about „up to 20 devices“ but that’s from a reseller page and probably talking bout the bridge.

@gluap maybe you can shed some lights on this.

I know of nobody having tested that many devices, so I can’t say for sure. But I also don’t know how how there should be an arbitrary limit on the number of devices. Maybe its a value where the radio crosstalk between devices affects usability.

Actually the migration docs on pyduofern hacs repo says

(4 hex digits as code required, last 4 digits if migrating from FHEM, 10 digit devices are not supported as of now)

I just didn’t see sense in making a 6 digit code and forcing users to enter the always same first two digits. If only 4 digits can be chosen it’s a for digit code. So the first two digits of the FHEM code are hardcoded in HASS.

Yes, I think your last sentence might be the actual reason (makes sense to me) for the vendor (or the resellers) to note this:

Hi , have the same issue than @Spartacus Spartacus. The card if the addon is empty. Is that normal, did this still work?

Yes that’s normal.

There‘s no GUI for control nor showing devices or entities.

I recommend reading the GitHub readme.

English is not my f favourite :slight_smile: ok
I only habe the USB stick at the moment, devices will come tomorrow. I will see if than will do something

Is it possible to pair a device using its radio code? As described here or in a similar way?

@gluap when starting the service duofern.sync_devices, I get the error

AttributeError: ‘ConfigEntries’ object has no attribute ‘async_setup_platforms’
