+This`plant`component lets you merge moisture, conductivity, light intensity, temperature and battery level for a plant into a single UI element. It also supports setting minimum and maximum values for each measurement and will change its state to "problem" if it is not within those limits.

+To use your `plant` sensor in your installation, add the following to your `configuration.yaml` file:
