Humie is activated when the internal sensors detect changes in humidity and temperature that are higher or lower than the threshold values. Thresholds can be set according to the area that Humie is monitoring and ‘normal’ conditions for your region.
Humie needs a cellular sensor, like Flowie, Flowie-O, Sensor Relay, Sentree or Sumpie to work. When it detects changes, Humie communicates with the cellular sensor which informs you by email, text or mobile app notification.
