* changed user config * added lightsensor module * changed Pin Adresses * Added I2C Lightsensor Added the I2C Lightsensor and Switchted most Pins * removed some debug to serial removed some debug stuff was send to serial console * Merge with Master * Too much things for arduino uno per default remove sensors for it * Adding I2C Module function Opens the Door on OpenMQTTGateway for "i2c Bus Modules/Sensors" * Fixing BH1750 detection Fixing the detection for a missing BH1750 Module * Add libraries and define sensors depending on wiring type #63
