Added tmp102 temperature sensor support (#929)
* Added tmp102 temperature sensor support * Added sensor to test3.yaml * Moved docstring to component root * Tweak formatting from clang-format script * Removed extra newline at the end of the file to satisfy pylint * Update schema to match that of other single-value sensors In ESPHome, sensors that only expose one value do not put the sensor under another key. * Add missing import * Fix test after structural change to component * removed unused setting * Update esphome/components/tmp102/tmp102.cpp Co-authored-by: Otto Winter <otto@otto-winter.com> Co-authored-by: Guillermo Ruffino <glm.net@gmail.com> Co-authored-by: Jesse Hills <3060199+jesserockz@users.noreply.github.com>
