When a vent is connected to the Alea Cloud, the Vent Status shows a green connected icon. If a vent is not connected to the cloud (as shown below), the vent status will show the red 'not connected' icon:
Vents can show as not connected if the internet connection is lost for longer than 2 hours, or vent batteries are exhausted. Please check batteries and internet connection. If these do not resolve the not connected issue, please contact us at firstname.lastname@example.org.
