UPDATE: Apparently a second “save” fixed the parameter… 
Hello:
Can anyone help clarify the correct settings for Parameter 51? According to the the release notes, a value of “0” means “No Delay” and “1” means “700ms Delay”.
The Hubitat driver (Inovelli) however, sets the value to “1” if “Disable Physical On/Off Delay” is set to “Yes”
Thanks for your help
