Hi,
so I am completely new to the whole topic of zigbee, hass.io and so on. I bought all the components (CC2530 to flash as coordinator and so on), setup everything, watched lots of tutorials, also got the Aqara Sensor to work for a short time, but I do not completely understand how/why it works 
So I installed the Configurator, mosquitto broker, zigbee2mqtt. Did setup everything, switched on my Aqara Sensor (pairing mode) and got data in return:
zigbee2mqtt:info 2019-1-31 17:50:28 MQTT publish: topic âzigbee2mqtt/bridge/stateâ, payload âonlineâ

That was yesterday. Today I switched my raspberry back on and in the âOverview sectionâ I had 3 new circles (beside weather and the âmoonâ), one for temp, humidity, hpa.
Problem is it seems to work only for a short period of time, so I figured I must be doing something wrong.
Do I need the moquitto broker at all? Do I need to do something after hass.io recognized the Sensor under zigbee2mqtt? Like officially add it somewhere? Do I have to create an entry in the configuration.yaml under Sensors?
