Barometer & Temperature reading zero

I just had another look into this, and I did spot an issue where getPressure could end up leaving the Barometer on if it got just one bad value, which it seems could in some cases cause this behaviour.

I did try adding a reset as you did (but in the firmware) but it wasn't quite that simple - I think I may have to leave some delay to allow the reset to take effect.

I've fixed the issue above though, so if you try a cutting edge firmware now it may fix it
