Problem: press Nuki bridge button to obtain token

[StefanGebhardt]

Hi,

I find in my log of the homebridge these entries:

After pressing the button on the nuki bridge everything seems ok:

After some minutes I get this:

And a bit later the above mentioned problem occours again.

Any idea?
Thank you,
Stefan

Did you try and power cycle the Nuki bridge and restart Homebridge?

[StefanGebhardt]

Thanks for the fast reply and spending time on my issue.

In the past I rebooted, but seperately. Now I tried directly one after another and the log changed:
[29.8.2023, 21:11:16] [Nuki] Nuki_Bridge_C2A77A2: subscribe to event notifications
[29.8.2023, 21:11:16] [Nuki] Nuki_Bridge_C2A77A2: error: too many callbacks registered

I will have an eye on it and have a look if I have a fallback to the error. I will report.

Thank you again

[ebaauw]

See closed issues for the “too many callbacks” error cause and resolution. Homebridge NB will still work, but the Nuki bridge won’t send notifications, causing a delay in detecting state changes.

[StefanGebhardt]

I did nothing :-)

12 hours later and the same error again:

Is it a problem because I had the "too many callbacks" for a much too long time? (saw the solution but had no time yet to solve the problem)

[ebaauw]

I fear you might have hit a bug in Homebridge NB introduced in v1.4.6. Note the subtle difference in the bridge name between the “press button” and other messages. v1.4.6 now uses 8 hex digits for the bridge ID, but not consistently. You bridge ID is smaller than 0x0FFFFFFF, resulting in a leading 0.

To confirm, could you check whether you still get these messages for v1.4.5? You still might need to clear the callbacks.

if you still run into issues in v1.4.5, please re-install the latest version, make sure Homebridge is running in DEBUG mode, and capture and attach the Homebridge log file.

[StefanGebhardt]

Thank you again. I downgraded to 1.4.5 and had to clear the callbacks. Now no problems, just the update status line
[30.8.2023, 18:39:47] [Nuki] Nuki_Bridge_C2A77A2: Last Updated: set to "Wed Aug 30 2023 18:39:46" (from "Wed Aug 30 2023 18:38:46")

I will have a look if the problem occours again and then upgrade to 1.4.7 again. You'll get an info.

What I watched when pressing the button was this line
[30.8.2023, 18:22:09] [Nuki] Nuki_Bridge_C2A77A2: warning: recommended version: Nuki Bridge v2.15.0

My bridge has the firmware 1.24.0 - and is not upgradable. Could it also be a hint for problems? Any incompatibility?

[ebaauw]

I think there's two hardware versions of the bridge, one with 2.x firmware and one with 1.x firmware, see https://developer.nuki.io/t/nuki-bridge-firmware-release-notes-public-releases/2797. I wouldn't know how to idenitify te models (other than the firmware version), nor what the differences are.

My bridge reports 2.15.0, and that's the version I develop and test Homebridge NB against, hence the warning.

[ebaauw]

Should be fixed in v1.4.8.

[StefanGebhardt]

It runned two days with 1.4.7 without any further problem. I just upgraded to 1.4.8 and will see.
Thank you so much for your fast replies and your perfect support :-)

[ghost-ps]

@ebaauw, thanks for the update to 1.4.8, I had the same problem with one of my two Nuki Bridges!

Now with 1.4.8 everything runs smoothly and without any problems, I think this issue can be closed. 👍

Since 1.4.6 I had constantly the following in the log and I had to go back to 1.4.5 to get it working properly.

And also with 1.4.8 no problems any more. Thank you!
