One of my LYWSD03MMC reports 0C temp and 0% humidity after upgrade to v4.7

Downgrading to v4.6 brings it back to normal operation.

Identification string it sends on v4.7: ~~Hardware Version: LYWSD03MMC B1.4, Software Version: 4.7, Sensor: SHTC3 (SHTV3)~~ (scratch that. messed up console log) Hardware Version: LYWSD03MMC B1.7, Software Version: 4.7, Sensor: SHT4x vs v4.6: Hardware Version: LYWSD03MMC B1.7, Software Version: 4.6, Sensor: SHT4x

board: CHMLmini_TLW_v2.0 202107 HW: B2.0

Same issue: Home Assistant: why is Power Detected status? On ATC_v46.bin was status Clear.

Get sensor Settings in TelinkMiFlasher.html report zeros: (If I Set Default - it was still zeros)

Same thing for me.

Worked OK on v4.6, 0.00 values on v4.7 (both on TelinkMiFlasher.html and in Home Assistant), and working OK again after moving back to v4.6

Thanks for this firmware and all the improvements

Ver4.7 is still a Beta version. Not tested on all thermometer options.

---

The new version of ver4.7-beta is corrected for the SHT4x sensor.

---

Temperature and humidity are calculated using the formula:

value (0.01) = sensor.regiser * coef.k / 65536 + coef.z

Установив прошивку 4.7 бета получил удвоение значения температуры. Вернув 4.6 всё нормализовалось.

Коэффициенты для датчика исправлены.

How can i change humidity / temperature setting on v4.7? On 4.6 it was just temperature and humidity offset. Need to set temperature offset 0.5 deg and humidity -4%

Add offset to "Zero offset".
