just to get it right. You have the Eltako integration installed in HA and you use USB300 as radio transmitter. Did you successfully install the Eltako integration and did the integration accept USB300? Can it receive and send signals/commands?
If you want to teach-in new virtual switches from HA I think this is next level. You need to take free addresses. Some people use “00 00 B0 00” as start and just count them up. Those addresses must be entered in the actors so that they will react on it. In 14-series you can do that with the software PCT14 quite easily. I know almost nothing about 12-series so I’m just guessing from now on. For me it looks like, in 12-series you need to trigger the sender to send a tech-in message. I think the easiest way is to use a library like eltako12bus to send raw data telegram having the teach-in bit set. This should also work for all the decentralized actors. There you should be able to find the commands.
I you want to use the mentioned lib checkout the command ./eltakotool.py --eltakobus /dev/ttyUSB0 send_raw -data b'...'
With ./eltakotool.py --eltakobus /dev/ttyUSB0 listen you can simple check what telegrams are sent. By the way what tool are you using right now?
git checkout heating-and-cooling or better git checkout 9bf3f67 which is the commit id of a good test state.
./install_custom_component_eltako.sh
The installation script will overwrite the existing custom component of eltako but the configuratio will be kept untouched. For configuring the heating see the following example. The sneder is representing a control panel.
climate:
- id: "00-00-00-??" # device Id
eep: "A5-10-06"
sender:
id: "??-??-??-??" # controller Id needs to be entered in function group 3 as target temp. controller
eep: "A5-10-06"
In addition I’ve configured a temperature sensor in function group 1 and for cooling I send hardcoded messages via address ‘00-00-C1-09’ to set cooling mode for the actor. This ID has to be entered in function group 3 as heatpump function (137) if you want to use it.
The way how to control it in HA is not properly defined. Heating and cooling should actually be defined from outside by the heater control which is right now done by the control panel in HA for testing reasons.
So far everything works for me except that FAE14SSR is not detect the heat pump function via pyhsical switch (FTS14EM) that’s why there is the test of sending frequently a singal of a faked switch. The faked switch is working and I’m still trying out how the pyhsical one should work.
When testing the whole thing please keep in mind I’m still testing and things change often. Therefore I would recommend to use the commit id 9bf3f67 instead of the branch.
If there is any bigger progress I can let you know.
Regarding 2. (FSA12 and FSB12) for teaching things in - same what I wrote @heubie. To get the addresses my first idea would be to listen to the bus so that you get all commands listed and then trigger a switch so that you can see what is reacting to it. Hope this is not too much effort.
Yes it is installed and I use an USB300 as radio transmitter.
I have the Enocean integration working with 4 dimmers. I have a R485 to USB converter connected to the Eltako bus and can log the commands that are one the bus via a pc and serial monitor software.
My next step was to disable de Enocean int. and install the Eltako int. This works and I selected the USB300.
I added some lines to my configuration and switched on logging to test.
Regarding 1:
That reads extremely promising. I will start testing as soon as I can.
The FAE14SSR and the F4HK14 look pretty similar and they have the same settings and sensors, so this should work
Regarding 2:
I am not easily able to look inside the BR12 Bus as it sits behind the Gateway. My Setup is a BR14 System with a Gateway to BR12 and some older actors behind it (I got them cheap and it works flawless).
Not sure if thats neccessary anyway, as (at least for me) it would suffice to simulate a binary sensor (aka switch) on the BR14 Bus that gets replicated on the BR12-Bus just like the other physical Sensors.
BR12 is monodirectional. No answer.
The teach-in way might be the “proper” way.
The easy way would be to just imitate an already existing physical binary sensor. It does not really matter (for my use case at least), that the light reacts on a button press that actually came from HA and not the real wall switch.
For me this looks good. Just checked the data which looks correct too.
Maybe one thing if you read the messages from the serial bus with another software if could be that it never reaches the USB300 if the software behaves like a queue.
Except the missing ‘:’ after eltako and many too spaces in the configuration it looks good.
I switch on debug and I no programmer but I think something is going wrong.
Could you comment on this?

yes, the serial interface crashed. In this case it takes the whole eltako integration down. There is unfortunately no auto-reconnect yet implemented.
The serial-bus is running in “parallel” and there is a handover implemented with a queue.
I don’t know very thing in detail but here is the thing: Eltako is using RS485 bus standard and therefore exists an serial library which is used in the Eltako integration.
It looks that USB300 is using a simple UART protocol and the enocean integration uses kipe/enocean library.
In branch heating-and-cooling I put some more helping things and prepared among other things that gateways could be defined in the config. So far I can distinguish between Eltako FAM14 and Eltako FGW14-USB which makes no difference for the serial lib but for the command you can send. With FAM14 you can e.g. completely program all actors or read the full-memory.
With branch heating-and-cooling you can optionally specify the gateway like this:
eltako:
gateway:
device: fam14 # In the code I've already prepared to define USB300 with 'enocean-usb300'
If I put the following into the config it uses the enocean lib instead of RS485.
eltako:
gateway:
device: enocean-usb300
...
It starts then the other serial interface: 2023-11-08 23:45:15.400 INFO (Thread-5) [enocean.communicators.SerialCommunicator] SerialCommunicator started
Obviously, it does not work for me because I only do have FAM14 and FGW14-USB and it almost directly stops.
What you need to do for testing is:
Install Eltako Integration normally via HACS
Add gateway section with USB300 like above into the Eltako config
Checkout the heating-and-cooling branch like described in earlier post and use the branch name heating-and-cooling
if you run ./install_custom_component_eltako.sh it will automatically restart HA otherwise you need to do it manually.

But when I send first an “ON” and direct after that an “OFF” to the same FSR12 relay via my old FHEM installation these messages pop up. So the USB300 works. the problem is in the conversion.

I’ve integrated now the climate controller which almost works quite fine. Everything is still in heating-and-cooling branch.
One thing which is not working well for me is to send a teach-in telegram to the FUTH so that it takes over the set target temperature from Home Assistant. Therefore I’ve added a teach-in button in HA which sends the telegram regarding eltako docs but the FUTH is not accepting it.
I bought two usb to RS485 converters to do some testing. Both are connected to Eltako bus. One of them is connected to my windows pc and with serial monitor software I can see the messages on the bus.
The other one is plugged in, in my NUC which runs HA. I tried both ‘fam14’ and ‘fgw14usb’ as the gateway and in both cases there is something visible on the Eltako-bus. As a reference I put the normal messages also in there.

, sitll sending the eltako command. They differ. I’ll try to fix it.
