- Restored disableIRQ flag as problems occurred on AVR.
The default of this flag on AVR is false so interrupts are allowed.

waiting for LOW in handshake to trigger the sensor.

- cannot rise fast enough to be read back as HIGH.

Since 0.4.14 there is **experimental** support for the Sonoff Si7021 .
No hardware yet to test this myself, but it is confirmed to work.(see #79)
Seems the Sonoff Si7021 sensor is very sensitive in the wakeup timing.
This behavior needs to be investigated in the future.
