Even if the driver had a refresh button it would not do an instant refresh. Its a sleepy battery device and it only listens for commands every 12 hours (by default).
Do you know what model of the ZSE40 you have exactly? Easiest way to figure it out would be the firmware. If the major version is 32, try out this driver instead: [DRIVER] Zooz Sensors Advanced (ZSE40 / ZSE44)
With that driver you could manually change the wakeup to be shorter to something like every 1 hour and then a refresh would happen at most within an hour of calling it. If you want to try it let me know I can tell you how to set the wakeup in the driver code or with a zwave command.
Major version less than 32 should still work on that driver but its not fully tested since I do not have an older one.
