Add a delay between commands

[jmello86]

I have several fans, and when I toggle the fan and lights on all of them using Homekit through HomeBridge, one or more of them do not respond. I have done some troubleshooting, by creating a shortcut that adds a delay between commands, and that works reliably. I am thinking that the commands are passed through the Bond Bridge too quickly, and only the commands that are able to be completed by the bridge are executed. I think that this problem could be solved by adding a configurable delay between commands. In my testing, 2 seconds was quite reliable, with some misses, but 3 seconds between commands worked well.
Thank you
