Hi,

I wanted to run some regular updates today, but I kept on getting issues with some dependencies such that I ended up uninstalling some, in order to check if I could just reinstall them. Unfortunately, some of them were quite critical such that I ended up flashing the entire device ...

Anyways, I do have a working axon S605 again (for some reason, it even still had my local files on it). but it now seems your debian repo isn't reachable: https://repo.unipi.technology/debian . Any idea what might be the issue and how to resolve it?

Right, so it indeed looks like a very high debounce time!

Strange, since I thought I had already checked that with the web view / can't recall changing it myself.

Anyways, I ran the firmware updates again, and now it's fixed! Thanks a lot!!

@martin-kudláček I did try they approach you suggested:

• I did not have my own custom software running right now (or before), so this shouldn't have been the issue
• I did check first for e.g. di_2_13: reaction was pretty much instantaneous
• Afterwards, checked for di_2_27: same reaction time as when I check with the LED indicator lights

Any other things I can check? Thx!

Update: I did check the issue with the faulty DIs again and I did notice that they actually still do respond -- but only after a 10s delay. This delay seems consistent for all the DIs. Additionally, it all concerns the upper 4 DIs (27...30) in all cases.

My guess is thus that it's probably not due to a hardware issue but rather a firmware issue.

Is this a known issue? Could this be related to the latest firmware upgrade?

Thanks for the quick reply. I did try the upgrades as you suggested.

There was no dist-upgrade to perform -- could run the firmware upgrade for L303:

After testing the involved DI ports, I still could not see any LEDs lighting up ... Would it make sense to break the seal and have a look at the DI board itself? Or what would be the best next step to check?

I did buy a Neuron L303 and M303 somewhere last year, to get acquainted with the hardware and to write software to read the digital inputs (e.g. https://github.com/mhemeryck/unipitt).

Now that I am nearing the end of the electrical installation of my house, I did start wiring up all of my push buttons, only to find out that a large number of them simply do not work. I first figured it could be related due to the software (I did read there was an issue with the sysfs SDK on which my implementation was based), but the LEDs on the unipi itself does not even light up for these DI.

I am hoping it could be a software issue -- but since the LEDs aren't even showing I actually fear for a hardware issue. Can you help me to further debug this?

Hi all,

Just wanted to share with you that I did integrate you driver for the axon s605 into the upstream python-dali library; see https://github.com/sde1000/python-dali/pull/59

It's not part of any tagged release yet, but it should be part of the upcoming one.

I have a similar for my Neuron L303. I didn't check via Mervis, but I just noticed that the indicator LEDs on the unipi itself was not reacting in any way anymore for some specific DI (others still working).

Do you think this is due to the same firmware issue or a more fundamental hardware issue? And why would I only have this issue now? I have only been running my unipi for some debugging purposes up until now (it's just when experimenting with my actual full set of push buttons that I started to notice this).

FYI: got my DALI bus driver in the mail today and did the full setup; managed to get everything up and running!

Will keep you posted on any further development wrt to the upstream python-dali library / any MQTT front-end I'd like to add.

@martin-kudláček yeah, I guess it does indeed make sense to have a separate power supply from a network point of view. I'll try again as soon as I will be able to get one.

Apart from the hardware setup, do you have any further documentation on how to address the DALI busses? From what I understand from your python implementation, you just have a modbus server running which you use to update specific registers. I guess this should be good enough for now, but given I'd like to translate between MQTT events and the DALI bus, I would also be interested in learning how to directly interface with it.
