-- `bool enabled `: Enable or disable temperature alerts. Enabled automatically by `onTemperature()`, but you can use this method to temporarily disable the alerts. Defaults to `false`.
+- `bool enabled `: Enable or disable the temperature sensor. Enabled automatically by `onTemperature()`, but you can use this method to temporarily disable the sensor and therefore the alerts. Defaults to `false`.
 - `MCP9804_Resolution resolution = R_DEGREES_0_0625 `: Set the resolution (precision) of the sensor. One of:
     - `R_DEGREES_0_5000`: +0.5 C
     - `R_DEGREES_0_2500`: +0.25 C
     - `R_DEGREES_0_1250`: +0.125 C
     - `R_DEGREES_0_0625`: +0.0625 (default)
 
   See the sensor's [data sheet, section 5.2.4](http://ww1.microchip.com/downloads/en/DeviceDoc/22203C.pdf) for more details.

 - `int8_t lower`: Alert when temperature in Celsius is lower. Defaults to `0`.
 - `int8_t upper`: Alert when temperature in Celsius is higher. Defaults to `30`.
 - `int8_t critical = 55`: Alert when temperature in Celsius is higher. Defaults to `55`, above which you run the risk of battery failure.
