Description
I've found that the setpoint PV sometimes doesn't update in our Lakeshore 340. So I created this workaround:
https://github.com/APS-4ID-POLAR/ipython-polar/blob/a22606fbf39bb71b375b41da94ebbec6507eb12c/profile_bluesky/startup/instrument/devices/lakeshore340.py#L16
This might be some sort of issue with EPICS?

Research direction
Start by reading profile_bluesky/startup/instrument/devices/lakeshore340.py around line 16 and reproduce the intermittent setpoint PV behavior on the Lakeshore 340. Determine whether the missing update is in this device configuration or EPICS, then document the cause and verify that the setpoint updates reliably.
