Hello Everyone,
Welcome to the thread for discussing Nikobus custom integrations. Nikobus is the predecessor of Niko Home Control.
To install this custom integration, please use HACS. The repository to add is: GitHub - fdebrus/Nikobus-HA.
For detailed installation instructions, refer to the GitHub page.
Your feedback is welcome!
Hello,
Thank you for creating this addon.
Now I’m using OpenHAB with Nikobus, since HA couldn’t handle Nikobus.
I’m setting up an VM-ware to test HA, so I can see how this works, and that i can do the same as OpenHAB. Most integrations already working, only Nikobus has to been implemented. I have already a problem with the first setup sceen.
I tested it with /dev/ttyUSB0, but get an unknown error. What do I have to use if I test in on a VM-ware. I use a Serial to USB device ‘Future Devices FT232R USB UART’. This is the same that I use with OpenHAB tha work withou any problem.
According to the hardware list in HA, /dev/ttyUSB0 sound be fine
Never mind. I got it to work.
My mistake. I forgot to copy the configuration-file 
I need more tester to discover potential issues. Please revert with any findings, I will enhance the error reporting so it reports on the missing configuration file vs unkwown error 
Do you have a feedback module with feedback led’s ?
New release is out. With this new release as a button get pressed you can choose between various triggers to be used on your automation.
Check readme on github for full details.
I don’t have any feedmodules with led’s.
It’s very nice that you added nikobus_long_button_pressed, nikobus_shot_button_pressed
The only problem that that you can configure 4 types of duration in the Nikobus software.
I have used those 4 types in my configuration. It’s no problem to update the modules when pressing 0,1,2 or 3 seconds, because I can include all modules that have impact with all combinations.
The only thing that I can think about is that I use a 3 seconds press for the ‘All out’.
Now I use OpenHAB and there it can be detected. Then I trigger also a rule that shut off also all the other devices, besides Nikobus, that are connected. Like Shelly’s, Music amplifiers…
Thank you very much for the addon. I wrote a little program to convert the OpenHab config-file to ‘nikobus_button_config.json’, and ‘nikobus_module_config.json’ so I don’t have to config all modules an buttons again, because I have 152 device of nikobus now in HA.
We can modify the code to add trigger for
in the latest release, check nkbactuator.py
this piece of code is waiting for a button to be released, and calcule the time between start and end of press.
So today, it only uses self._long_press_threshold_ms which is defined by default to 500ms.
We could add
self._press_threshold_1000ms
self._press_threshold_2000ms
self._press_threshold_3000ms
and trigger nikobus_1sec_button_pressed, nikobus_2sec_button_pressed, nikobus_3sec_button_pressed, … accordingly
Let me know, I can code a new release if this matches your requirements
async def _wait_for_release(self, address: str):
try:
start_time = self._last_press_time
while True:
await asyncio.sleep(self._debounce_time_ms / 1000)
current_time = time.monotonic()
time_diff = (current_time - self._last_press_time) * 1000
if time_diff >= self._debounce_time_ms:
_LOGGER.debug(f"Button release detected for address: {address}")
# Calculate press duration
press_duration = (current_time - start_time) * 1000
if press_duration >= self._long_press_threshold_ms:
_LOGGER.debug(f"Button long press detected for address: {address}")
self._hass.bus.async_fire('nikobus_long_button_pressed', {'address': address})
else:
_LOGGER.debug(f"Button short press detected for address: {address}")
self._hass.bus.async_fire('nikobus_short_button_pressed', {'address': address})
await self._button_discovery_callback(address)
self._last_address = None
self._press_task_active = False
self._press_task = None
break
New release,…
Added events to be used in your automation trigger
nikobus_button_pressed
nikobus_button_released
nikobus_long_button_pressed
nikobus_short_button_pressed
nikobus_button_pressed_0 Button press detected for less than 1 second
nikobus_button_pressed_1 Button press detected for 1 second
nikobus_button_pressed_2 Button press detected for 2 seconds
nikobus_button_pressed_3 Button press detected for 3 seconds
Also fully support button with feedback leds
Thank you, I will try it.
Is it possible that I can’t install it via HACS, and that the automatic update also is not working. It’s no problem, I can always download it from github, but it would be easyer that I get a message that there is a newer version.
In HACS I only see this if I search for Niko.
You need to add my custom repository to HACS,
3 dots top right in the HACS screen then
Updated the readme file on the github accordingly
custom_repository/nikobus.nikobus_module_conf.json.default to your Home Assistant configuration directory, remove the .default extension.Hey! I am sorry to ask these super basic questions, but:
My parents bought a Nikobus System when it was super new but have zero tech skills. i dont have a lot of knowledge with electrician skills, but i am a software dev. How does the hardware side of this work? for example, Nikobus-Interface für Niko Home Control I requires a pc link, pc logic or feedback module. What does this integration need? how does it(home assistant server) communicate with nikobus, using cable, wires?? how can i check if i have the module?
these are the notes from my electrician:

You will need a PC-Link module, a Feedback module or a PC-Logic module, they all look the same
From the list of components you shared, it seams you do not have any. Then go for a PC-Link module. They are plenty on second hand market.
Next, your need to connect this module towards your HomeAssistant server, 2 options over USB or TCP/IP with a bridge.
Common to both
RJ11 cable
RJ11 to DB9
Here is a tutorial about the USB cable
(Home-Made Cable RJ11 / RS232 (DB9) for Niko PC-Link - MForge)
There are many cable configuration possible, if you go for home made, you will be sure of the config of the cable. If you buy already made rj11 to DB9 make sure it matches the wiring diagram as descripbed in the tutorial.
if USB
USB 2 SERIAL
if TCP/IP
HF2211
Detailled config for HF2211 is available on my github
At the moment I am using openhab as integration for my nikobus setup, but I really want to drop that setup for this custom Nikobus Integration. I am using a serial-to-usb connector between the feedback module and the Pi running my home assistant. Everything seems fine configuration wise, however, I don’t seem to be able to read or write the outputs of the controllers. Every entity is indicated as OFF, and switching it to ON and OFF again doesn’t have any effect on my lights.
The hardware works fine with openhab, so I don’t think anything is wrong there.
Any idea what I am missing?

What’s your module address in the module_config.json file ? Have you copied it from openhab integration or Nikobus software ?
You need to record it as in the nikobus software, not openhab.
eg module with address 91AD in openhab is AD91 in Nikobus software and must be AD91 for this integration to work.
Could you confirm ?
Party-time … indeed, I was using the openhab address, as I don’t think I can use the original nikobus software anymore 
It is working now, thanks a lot!
Do you have button with feedback ? since you setup with ‘has_feedback_module’: True.
If you do, I’m very interested at received your experience, button with feedback integration is a new feature, not fully tested yet.
thanks !
I had 3 of them, 2 are totally broken and cannot be used anymore.
That’s a little off-topic, but more and more of those bus-push-buttons are falling apart, and cannot be replaced anymore 
I’ll test the last one later on, and let you know.
There are some on 2ememain.be, pitty it’s pickup only… too far for me.
2nd hand … I wouldn’t do that anyway, chances are they will also fall apart after a short period.
Anyway, I have a technical remark, not related to the feedback leds yet: I have 2 controllers with 12 outputs, 1 controller with 4 outputs and 1 dimmer with 4 outputs.
I don’t have any buttons registered just yet, so the state of my outputs is based on the interval reading, I guess?
I have the feeling that:
If your buttons are not defined yet, and you use feedback module refresh rate, which is default to Nikobus and cannot be changed. It could be up to 30min for a specific module refresh. That’s why it’s important to define your buttons that will keep the integration in sync with Nikobus.
To your problem, try « configure » in the integration, remove feedback module and try a refresh rate of 120secs, so all modules will be refreshed every 2minutes.
See how that behave, next share your modules configuration file and a debug log over a full refresh period.
