With the next release of our Nuki apps, MQTT can be activated and configured throughout the apps.
Please post your feedback in the appropriate forum thread.
The Android version is finally available in the public beta.
Having issues to connect to MQTT using the App. When I disable debug mode on my Nuki 3 Pro I see the following in my mosquitto log: I provided User and Password
2023-03-21 16:01:07: New connection from 172.20.1.99:52438 on port 1883.
error: received null username or password for unpwd check
When I enable debug mode I only get an error message within the app. Hostname could not be resolved ?? I use an IP address.
Yesterday I disabled debug mode, setup MQTT in NukiAPP and all is working w/o any problems till now.
Nuki 3 Pro, beta firmware 3.6.0
App verison 2023.4.1 (beta)
Mosquitto MQTT broker running on Odroid H3 with Ubuntu.
Include connection to Home Assistant.
Please disable the debug mode as otherwise the MQTT provisioning will not work via the Nuki App.
Hi, in that case I get on both of my MQTT servers the following error:
172.20.1.99:52435 on port 1883.
error: received null username or password for unpwd check
so far so good. I`ve disabled debug mode and configured my mosquitto broker - all is working fine without a glitch
