Research direction

Start by reproducing the SNZB-02DR2 issue on firmware 1.0.5 with Zigbee2MQTT 2.14.1 and collect the missing debug log and database.db entry. Compare the reported temperature and humidity clusters and configured reportings with behavior before the update; done means external sensor readings are transmitted again.
