I posted about a delay for the relay in another thread. I think my use case is little different from what you are describing, however the delay part is the same. It was suggested to me to run a z-wave repair or 3, but I have a feeling the delay is somewhere else and it’s very possible it might just be something we have to deal with. Not a deal breaker for me as the device does what I need it to do, just a minor inconvenience.
