I have reviewed I2C_temperature_sensor and have written applications using i2c in the past. The problem is specifically the address collision.
I doubt that it is possible to power down the eeprom in the module. if your device had address pins then you might be able to readdress it with logic inverters, but it seems your device has the i2c address hardwired inside the chip. I think you should look for another device which has i2c slave device address pins. another (unattractive) option might be to put a converter chip between the BCM and the I2C that converts from UART to I2C.,, but that adds a lot of complexity to something that should be simple. Maybe a device with a SPI interface is an option too. Good luck.
Unfortunately, this conflict exists and you will need to bit bang to address your device.
