Automatic discovery not adding mqtt devices

Hello guys,
I try to add Xiaomi temperature and humidity sensor. zigbee2mqtt and broker are installed and configured. Device is added to zigbee and I can see readouts in logslogs:

zigbee2mqtt:info 2019-12-22 20:21:01: MQTT publish: topic 'zigbee2mqtt/0x00158d000363f2ef', payload '{"temperature":25.92,"linkquality":31,"humidity":53.65}'

I’ve also added configuration to HA as in (https://github.com/danielwelch/hassio-zigbee2mqtt)
First of all I thought that broker in HA configuration.yaml part is wrong so I used all: ip, ip:address, core-mosquito literal but non of them worked

mqtt: broker: 192.168.88.231:1883 #here I tried different settings discovery: true

However the temperature sensor does not pop up in dashboard nor in availabe sensors (entities file).

When I add the mqtt sensor manualy all the readouts are ok.
Do you know what can be the issue ?
Thanks

Similar issue for me…
FYI, I added an issue on the add-ons github repo : https://github.com/home-assistant/hassio-addons/issues/1190

Hi, after multiple reboots of HA, it’s working now, for no reason, maybe cache?
