Attiny85 I2c questions

I am using the tinywire library to try to make an Attiny85 return a sensor reading and send it to an arduino Uno. My hope is to have multiple Attiny85 chips doing this at the same time. I am sure of how to code the arduino uno to receive the data to the Attiny85. Any suggestions would be appreciated greatly. Code below is snippet from the Attiny85. I have searched high and low and can not find any examples.

#include <TinyWireS.h>
#include <usiTwiSlave.h>
#define I2C_SLAVE_ADDR 0x26
#define NUM_READS 100

int sensorpin = 3;

void setup()

void loop()
if (TinyWireS.available())


:) Perfect I have some reading to do....

Thank you for the write up. I ran your scanner code on the uno with the above code on the Attiny85 and it did not return anything. Not sure what the issue is. I' ll have to do more digging.
