Zigbee2mqtt add Zigbee device

At the moment im running hass.io on a Pi4 and have a cc2531 stick connected to it to be able to connect zigbee devices.
i have already installed both the zigbee2mqtt and the Mosquitto broker.
Whenever I try to pair my Xiaomi Aqara sensors with it the log shows the following:

zigbee2mqtt:info  2020-05-15 01:18:34: MQTT publish: topic 'zigbee2mqtt/0x00158d000446ce5a', payload '{"battery":100,"voltage":3055,"contact":true,"linkquality":115}'

so it does realize that there is something there, however it doesn’t add the sensors right away the zigbee2mqtt.io site states that to connect a device the log should show something along the lines of this:

zigbee2mqtt:info  2019-11-09T12:19:56: Successfully interviewed '0x00158d0001dc126a', device has successfully been paired

what am I doing wrong or how do I add the devices manually with the info provided form my log?
