My tempest just went into the severe power save mode where it only sample once every 5 minutes. Interesting is that while doing that it missed somehow a measurement from all the sensors, except the barometric and battery voltage. So no, temperature, brightness, humidity, wind, just pressure and voltage.
Of course, it is just a tiny problem, but might be an indication of some other problem which got unnoticed so far (is the timing correct for example)
BTW it also shows another problem. Well not exactly a problem but more like a difference. On the web version when a measurement is skipped, the line segment connecting the dots is left out, where as on android that line segment is shown.
