# How statuses work

### Devices can have 5 different statuses

Note that some of the statuses can be combined so that e.g a device status can be ONLINE and WARNING and ERROR at the same time.

Here are the statuses and their explanations:

1. ONLINE - device is receiving data within the time frame defined by the DUTY CYCLE setting.
2. WARNING - one or more of the sensors have a value that is under or over a threshold as set in the device settings.
3. ERROR - you need to check the sensors of the device, as there is a problem with one or more of the sensors.
4. OFF DUTY - more time has passed than the DUTY CYCLE allows since the device received data.
5. OFFLINE - at least 24 hours have passed since last receiving data.
