Go to the Configuration Data -> Node View Tab, where all commissioned devices are listed. There are two ways to remove a commissioned device from the list. The first way is to highlight the row in the Node View by clicking on the Icon (green checkmark or binocular icon) and hit the delete
key. The second method is to right click anywhere in the row and select the "Delete Node Configuration Data from CIT" .
If on the other hand you are seeing extra units in the Monitor Data tabs, and these extra devices have a yellow triangle symbol in the left column, then these units are not commissioned, and cannot be included in the daily report. If these yellow triangle units are turned off, they will eventually fall off the list once their last received data point is older than the amount of data you download from the DCAP.
