So I have about 12 zwave devices now and I am getting really slow response time to turn a light on. I hit the button hg, it shows in my hg summary widget as being on, but the light downt turn on for 5 to 30 seconds. I did the settings zwave heal and this has not helped. During the heal it looked like most of the always on devices could see most of the other devices, so I don't think there are any range issues.
I should note that this is intermittent. After several tries of long delays it seems to respond mroe quickly for a while. Some time later (next day?), then it takes a long time to respond.
