Options to use 6.5k thermistor #316

Is there a program path to change temp sensor from 10k to 6.5k? Due to intallation dbh002 on existing structure i dont want to use addiotion resistors or disaasemble floor to get the old temp sensor.

The termistor on the BHT002 is connected to the original MCU and has no connection to the ESP8266 microcontroller. So that cannot be configured. The most simple solution could be an additional microcontroller with analoge in (e.g. ATTINY) and a digital potentiometer faking the expected 10k thermistor. Analoge solutions or the integration in the programmable ESP might be more complicated.
