However, it is regrettable that the outdoor sensor does so only 2 measurements (temperature and humidity), the internal sensor measuring further CO2, noise and pressure.
Pressure except to live in a box, no matter whether measured inside or outside: the progress curves allow, showing trend, anticipate weather changes.
For noise, it is also preferred an internal measure (allowing many neighborhood disputes!), But an external measure could be interesting for those who live near the traffic lanes.
Finally, it is unfortunate that the extent of pollution is not done on the outdoor sensor: it is with such a feature would have been possible to imagine a giant measuring network of air quality.
