You can try the [RELEASE] Tuya Temperature Humidity Illuminance LCD Display with a Clock driver - install the dev. branch version linked to the second post of this thread.
I am able to configure the Sonoff SNZB-02 sensor to send updates as quickly as 10 seconds on 0.1 degrees Celsius change.
Reconfiguring the reporting intervals and delta requires that the sensor is awake at the time when the new settings are sent to the device. You can try pressing the device pair button at the same time when you click on the preferences Save button. EDIT: this does not work for SNZB-02
An alternative way to ensure the new reporting settings are accepted is to pair the sensor again to HE after the settings were saved. This works all the time with my device.
