Hi,
I was very happy to buy this sensor to start doing some relevant automation, but unfortunately, despite my noob efforts, seems cc2531 cannot catch this.
I run HA on ubuntu docker in VM of QNAP 
I have working mosquito broker thanks to an ikea tradfri switch check.
The device is supported according to https://www.zigbee2mqtt.io/devices/07047L.html .
If I go to developer -and publish mqtt messages i have only ikea switch.
autodiscover i saw that is on in mosquitto config.
i added some lines according to what i saw around here into config yaml, but still no clue ( restarted many times).
Many thanks to a good hearted folk that for sure will help me.
Config yaml added lines for mqtt are:
mqtt:
broker: core-mosquitto
port: 1883
discovery: true
discovery_prefix: homeassistant
username: xxxxxxxxxx
password: xxxxxxxxxxx
birth_message:
topic: 'hass/status'
payload: 'online'
will_message:
topic: 'hass/status'
payload: 'offline'
but i knew that was working since i added blitzwolf smart plug and automation is working nice when i push tradfri button and my lamp is turning on / off
switch:
platform: mqtt
name: priza.veioza
state_topic: 'stat/tasmota/RESULT'
value_template: '{{ value_json["POWER"] }}'
command_topic: 'cmnd/tasmota/POWER'
availability_topic: 'tele/tasmota/LWT'
qos: 1
payload_on: 'ON'
payload_off: 'OFF'
payload_available: 'Online'
payload_not_available: 'Offline'
retain: false
Solved. cc2531 is guilty of not founding new zigbee devices
