How do I know if the sensor is offline? 

In the sensors page within the group, you see all the sensors that are shared with the group with their status. The status shows the last measured data when the sensor was online, but when the sensor is offline a yellow triangle will appear. 

Why is the sensor offline?

There are three reasons why a sensor could be offline. The first and most common reason is a low or empty battery of the sensor. The second reason is that the sensor is not connecting to the network and the third is that the sensor is damaged. 

How can I get the sensor online again? 

The sensors within the group can be shared from different organisations. The owner of the sensor, the organisation, is named underneath the sensor title. Contact the user from the organisation that shared the sensor. He or she can take the following steps to get the sensor online again.
