TO REPRODUCE

Let Nuki Hub run a few hours. Then it is shown as unavailable in HomeAssistant for a couple of hours. Later, it automatically reappears and works as designed.

EXPECTED BEHAVIOUR

Connection stays stable.

Same here. If mosquitto Broker output is needed please just tell.

[iranl]

I suggest trying the latest PR with Arduino Core 3 and IDF 5.1.
Besides many changes to the networking stack it also includes nuki hub specific improvements regarding MQTT.

You can find the binaries here: https://github.com/technyon/nuki_hub/actions/runs/9711394389

Do note that these binaries need to be flashed using USB/serial once because of changes to the partition table.

[DeckardCain2014]

I tried flashing it with the Espressif Flash Download Tools, however it shows only 'null' in the command line and red fields in the UI

[iranl]

I find that to be a horrible tool and exclusively use esptools.

See https://docs.espressif.com/projects/esptool/en/latest/esp32/installation.html or https://www.flamingo-tech.nl/2021/03/21/installing-and-using-esptools/ for how to install esptools.

You can just use the command in the how-to-flash.txt file. You only need to change the COM port.

[DeckardCain2014]

Worked now. Different machine, different tool. I will update here how stable it is

[DeckardCain2014]

Basically it works now. However, the main lock topic is unavailable

[fir3drag0n]

Is there a solution to unknown state?
