For parasite mode, while waiting for conversion to take place, the oneWire pin needs to be set as an output (high) and then set back as input before reading back the temperature(s). This is true even for just one device on the oneWire bus. Maybe not true for all esp8266 modules but certainly the case for mine (Adafruit Huzzah)
