#Device status surveillance

Surveillance allows users to detect and quickly rectify failures or problems.
If the device is connected to the KNX bus system, the operating status of the device is indicated. To check whether communication is working correctly, it transmits a 1-bit communication object over the bus at regular intervals. If this object is connected with a KNX server, the status can be visualised or a message can be transmitted to notify the user of any faults.
