Your unit shows a constant noise level of almost 100 dB, that is very loud. You’ll probably need to contact Radu to find out whats going on with the unit.
Yes, I agree, 99db would be very loud in reality so seems something is wrong with the noise sensor. I’ve also noticed another issue – it seems the Pressure, Humidity and Temperature sensors also seem to flatline regularly after some time being online. See today for example, a few minutes after 6AM.
