Issue
The DMP panel uses a ‘disconnect’ command to gracefully close a socket. The original release of the DmpPI plugin did not implement this command. As a result, after a connection to a panel was made, then was disabled and quickly enabled again, the connection attempt failed several times until the panel timed out and closed its end of the socket.
Workaround
Wait a minute before enabling the panel, be patient.
