# I2C devices
2019-11-03 14:37:33 +00:00
Tasmota supports several I2C devices but to use them they mostly need to be enabled at compile time to solve possible address conflicts.
2019-11-03 17:03:32 +00:00
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.
