Is it regarding the missing Humidity, because it's only Temperature Sensor?

Research direction
Investigate the plugin's code that processes MQTT messages and maps them to Homebridge characteristics. The error indicates that the plugin expects a valid finite number for relative humidity but receives NaN from a DS18B20 sensor that does not report humidity. Examine the topic parsing logic (likely in index.js) to see if it unconditionally expects humidity data. The fix should check if the humidity value is present and a valid number before setting the characteristic. Also review the MQTT topic structure reported by the user to ensure the plugin correctly handles sensors that only provide temperature.
