You can try this custom driver : [RELEASE] Tuya Temperature Humidity Illuminance LCD Display with a Clock - #2 by kkossev
First, manually change the device driver.
Then, configure the maximum reporting period to 5 minutes, temperature and humidity sensitivity and click on 'Save'.
Finally, pair the sensor to HE again. The pre-configured parameters will be sent to the device during the pairing process.
You can experiment with temperature sensitivity less than 0.6 degrees and humidity sensitivity less than 6% ( these are the recommended settings from the manufacturer), but watch out whether the device will not start to send updates too frequently... if this happens, set the sensitivity parameters as recommended in the leaflet.
