AHT2x/AM2301B temperature and humidity sensor~
This feature is not included in precompiled binaries
When compiling your build add the following to
#ifndef USE_AHT2x #define USE_AHT2x // [I2cDriver43] Enable AHT20/AM2301B instead of AHT1x humidity and temperature sensor (I2C address 0x38) (+0k8 code) #endif
In the Configuration -> Configure Module page assign:
- GPIOx to
- GPIOy to
After a reboot the driver should detect the sensor and display sensor readings.
On some I2C sensors, like the AHT25, Tasmota might mistake the sensor for another one using the same address. This can be resolved by disabling the unneeded drivers.
For our example AHT25, the address might get confused with the VEML6070 UV sensor. You can tell Tasmota to use the other driver by issuing the following commands in the console:
I2CDriver12 0to disable the VEML driver
I2CDriver43 1to enable the AHT driver
An overview of all I2C drivers is available in the docs.
