Use of UPDATE
Use of the UPDATE command by automation provides a convenient way for the automation system to be aware of
changes as they occur on Maestro without the overhead on either system of constant command queries. Once a command
has been registered, Maestro will automatically queue a message to be sent to automation for that command when any of
its parameters change. The automation system will be made aware of these queued messages by receiving a SVC (08h)
response to a poll.
The following commands are supported for automatic updating:
