FYI, I discovered that streamDevice's redirection-to-records feature fails if the name of the destination PV starts with a number: https://github.com/paulscherrerinstitute/StreamDevice/issues/20 There have been multiple times in the past where streamDevice support that used the redirection-to-records feature worked in my development IOC but didn't work when I deployed it to a beamline. This problem wasn't discovered then because eliminating redirection from the support was easier than troubleshooting the redirection failure. This problem is very likely to occur at the APS. The PV prefix for development IOCs is often the developer's initials. The beamlines are numbered and the PV prefix for beamline IOCs usually begins with the beamline number. I hope this saves someone else a little frustration. Kevin
