Using webCoRE with Hubitat

So the good news is, waits do indeed now work correctly. But something still isn't right with the execution. Tried this simple piston (turn light on, wait 4 sec, turn light off):

The piston triggers properly and light does turn on, but never turns off; log shows no errors (that's the scary part) and says that physical command execution was skipped because it would make no change to the device:

As I recall CoRE had an option to turn off command optimization but I can't seem to find a setting to do that in WebCoRE.
