Just wanted to thank you again for the step by step.
Finally got back to this today. I’ve been busy moving RM4 rules to RM5 to take advantage of the optimized hub variables and nothing goes as smoothly as it should. Hub mesh was giving me a hard time updating the shares.
Anyway I got two Zooz devices added with no security - a zen26 and a zen16. Not sure if I had to do this process for the zen16 or not, but it worked all the same.
Rebooted the C7 and they were both on the zwave details page and discover pulled them right in.
Life is good
