Relay switching frequency

I'm using the Relay constructor and noticed there are milliseconds switching. Is there a setting to help smooth this out so it doesn't happen? It's not good for the relays to do this too much.

Also, I noticed in your examples, you used !relayState to get inverse High/Low. When set bangbang, I have to use relayState for bangbang to be on outside of the set bangbang time.
