Novice trying to pair a BLE-YL01 device

[bjornsmith]

Hi,
I have spent two days trying to integrate my BLE-YL01 device, but without any success. I have of course Zigbee Home Automation, MQTT and Zigbee2MQTT extension installed. The system is running fine with lots of other Zigbee devices installed.

What is the basic procedure to add this BLE-YL01 device? I press the red button on the device for 5 seconds and the led start to blink. Are there any pairing action in Zigbee2MQTT (button to click) to be made, or should the device be added/paired using MQTT or Zigbee Home Automation?

Please excuse my ignorance but I'm completely confused. After restart of Zigbee2MQTT the log shows:

[17:27:42] INFO: Preparing to start...
[17:27:42] INFO: Socat not enabled
[17:27:42] INFO: Starting Zigbee2MQTT...
Starting Zigbee2MQTT without watchdog.
Onboarding page is available at http://0.0.0.0:8099/

You first need to complete the onboarding procedure, after that z2m will start and you can pair devices.

Hmm, still confused. It says the on-boarding is available at http://localhost:8080. I assume in my case http://192.168.11.124:8080/ since 192.168.1.124 is the ip-address of my Raspberry Pi. The log says "Onboarding page is available at http://0.0.0.0:8099/" so I tried with http://192.168.11.124:8099 as well, but I get no connection on these ports.
With what tool and how can I reach this on-boarding url???

The network settings in my HA indicates completely different ip addresses. See attached file. I'm totally lost here...
