Subject: [PATCH] Add Support for AHT30 Temperature and Humidity Sensor
 (#19922)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Update xsns_63_aht1x.ino

Support for AHT30 added. Fixed command for loading factory calibrated data and reset command, added needed delay after read command and increased measurement period to reduce heating of sensor.

* Update xsns_63_aht1x.ino

* Update xsns_63_aht1x.ino

The reset command is aligned with the AHT10/20/30 datasheet.

* Update ru_RU.h

Translated Dew Point to russian Точка росы for sensors

* Delete tasmota/language/ru_RU.h

Will go to separate PR

* Add files via upload

* Update ru_RU.h

Partial translation update

* Add files via upload
