Finally found the solution. Details: http://arduino.stackexchange.com/questions/29546/attiny85-i2c-lcd
The libraries are not the same. This setup with the LiquidCrystal_I2C from the Arduino website does not work. As mentioned earlier, I have tried your configuration with pull-ups. It was absolutely not a hardware issue.

I only put these two lines in the Loop to actually see the data on the serial monitor, took me a day or two to figure that out! Not sure why it fixed anything.. unsigned int data = man.getMessage(); Serial.println(data);

Using an I2C LCD on Attiny85
Followed the steps exactly and the IDE returns this error: /home/thijs/.arduino15/packages/ATTinyCore/hardware/avr/1.1.1/libraries/Wire/Wire.cpp: In member function 'void TwoWire::setClock(uint32_t)':/home/thijs/.arduino15/packages/ATTinyCore/hardware/avr/1.1.1/libraries/Wire/Wire.cpp:85:3: error: 'TWBR' was not declared in this scope TWBR = ((F_CPU / frequency) - 16) / 2;
Replaced the receiver with a Pro Mini for the photo, LiquidCrystal does not work for me on the ATTiny no matter what I try.
ok :) haha. I also thought I screwed up the 2 wires, switched them over but then the display goes all crazy, flickering or no backlight at all. pin5->sda, pin7->scl

Thanks, I've followed the link, then followed all the steps, it's not clear what core the guy uses but I tried it with multiple cores and still get the same result. Black boxes on one line. Attached it to the Nano directly and then it works fine, must be something about the Tiny I do wrong..
I've sent you a private message to keep things 'clean' in here.
I get no errors but only black squares. Followed the instructions carefully and tested the LCD with Arduino Nano first.
Great stuff, the communication works very good. The LiquidCrystal seems to be a much harder nut to crack, I'm using TinyWireM and a LiquidCrystal library with Tiny85 support but still I get nothing more than a flashing backlight :( Ant more information on your display setup is welcome!
