ESPHome. The :ref:`I²C Bus <i2c>` is
2018-05-13 11:37:02 +02:00
required to be set up in your configuration for this sensor to work.

Currently, the platform doesn't support activating the built-in heater,
2018-05-13 11:37:02 +02:00
as it seems to only be rarely of use. If you need it, please open an
issue.
