Debug log

No response

Notes

No response

Start by reproducing the color-temperature change with the reported TS0505B database entry on Zigbee2MQTT 2.13.1, then compare the behavior with 2.12.1. The missing debug log means the relevant device handling and reported color-temperature behavior will need to be traced before identifying the change. Done means the bulb transitions between cold and warm white when changed through HA or Z2M, with regression coverage if the project provides a suitable test path.
