“Who changed the set point? Why did that device stop?”
The BACnet protocol does not support authorization or authentication. Use our Watchdog tool to monitor where the commands that changed set points/device states came from. Our tool allows you to monitor some or all devices/objects/properties.
The CAS BACnet Watchdog records MAC addresses, IP address, messages and other information useful in tracking down unauthorized/unexpected commands. It’s easy to install and easy to use.
