RDM with OLA
From wiki.openlighting.org
RDM devices can be configured through the web interface (only partially complete) or from the command line. Even if you don't have any RDM devices you can still experiment with RDM because the Dummy Plugin creates a fake RDM device.
Device Discovery
The ola_rdm_discovery tool displays the UIDs found for each universe.
$ ola_rdm_discover -u 1 414c:010014b3
Passing the -f options will force the discovery algorithm to be run for the particular universe. This won't produce any output unless and error occurs.
$ ola_rdm_discover -u 1 -f
Device Configuration
The ola_rdm_get and ola_rdm_get commands allow attributes of the devices to be controlled. The first thing to do is to view a list of all known attributes:
$ ola_rdm_get --list_pids boot_software_version_id boot_software_version_label capture_preset clear_status_id comms_status default_slot_value device_hours device_info ...
To fetch the value of a PID from a device use:
$ ola_rdm_get --universe 1 --uid 414c:010014b3 device_info
Changing the value works in a similar way:
$ ola_rdm_set --universe 1 --uid 414c:010014b3 comms_status # clear the communication counters
The full list of options can be found by running with --help:
-d, --sub_device <device> target a particular sub device (default is 0) -h, --help display this help message and exit. -l, --list_pids display a list of pids -u, --universe <universe> universe number. --uid <uid> the UID of the device to control.
Useful Tricks
If you're using bash, it's worthwhile to set up tab completion of PIDs:
$ complete -W "$(ola_rdm_get -l | xargs)" ola_rdm_get $ complete -W "$(ola_rdm_get -l | xargs)" ola_rdm_set
