Problem setting the wake up interval for aeotec z-wave water sensor DSB45

[proj964]

When using the device>wakeup interval>write changes with the device set manually awake, nothing appears to happen. The event viewer only says forced writes followed by nothing. The device continues to wake every 4 minutes. Several intervals chosen from 5 minutes to 1 hour; makes no difference; still is on an every four minutes cycle.

The device page has a "set configuration" but no read configuration; seems odd.

Also, how does one issue a  Wake Up Interval Capabilities Report Command and get a result?

Thanks, Jon
