@bobbyD mentioned something about the z-wave channel in the Iris smart plugs possible being an issue (or that's how I interpreted the comment). I'm waiting to hear back from him on that.
I've done quite a bit to get my home network optimized so I don't believe its a networking issue. The HE hub and Hue bridge are connected via ethernet to a WAP sit less than a foot away. Do you think I should move the HE hub further away from the WAP?
Troubleshooting and the process of elimination are probably two of my best traits
Thanks for the help and support.
