I2C devices

Tasmota supports several I2C devices but to use them they mostly need to be enabled at compile time to solve possible address conflicts.

Using command I2cDriver individual drivers can be enabled or disabled at runtime allowing duplicate I2C addresses at compile time. Use the Index from the table below to control I2C drivers like I2cDriver10 0 for disabling BMP support.

Supported I2C devices

The following table lists the supported I2C devices
