We are releasing a beta firmware for the LZW36. See the link for bug fixes and enhancements. One notable addition:
Parameter 51 to disable the 700ms delay from when you press the physical on/off buttons. This is similar to what we released on the switch a bit ago.
You will need to update your Hubitat driver or SmartThings device handler to expose the new setting
This firmware should be stable, but if there are any issues, please let us know.
