How often does Marcell report in with temperature and humidity data?

Current temperature and humidity is checked against your settings every 10 seconds. If the current readings are outside of your safe range, an alert will be sent immediately. If readings are within your safe range, they are recorded every hour locally and uploaded every 8 hours to the cloud service for historical logging. At that point, this data is displayed on the web site in graph or chart form.

In case of an alarm condition, the alert is sent right away!
