 #### Base interface
 
 - **bool begin(int dataPin, int clockPin)** begin function for ESP8266 & ESP32;
 returns false if device address is incorrect or device cannot be reset.
-- **bool begin(TwoWire \*wire = &Wire)** optional set the wire interface 
-for platforms with multiple I2C buses. **begin()** calls **reset()** which can take up to 15 ms. 
+- **bool begin()** calls **reset()** which can take up to 15 ms. 
 - **bool read()** Reads both the temperature and humidity.  
 Initial release has a blocking delay. 
 - **bool isConnected()** check if sensor is reachable over I2C. Returns false if not connected.
