Ran into a similar problem counting pulses on a wind sensor. The parts here are hard to find so I wanted to share some code to provision an attiny85 for pulse counting and making it available on i2c. low_pwr_attiny85_i2c_pulse_counter.ino ยท GitHub
Works great for my low power Boron weather station.

that's cool, thanks Tyler!
