This week I have found that lighting scenes that set a dimmer on 1 or more of the devices, will cause the non-dimmable devices to not fire.
As an example, if I set up a scene that has dimmable bulbs (zigbee), dimmable outlets (z wave), and on/off switches (GE z wave wall toggle), and do not set dimmer levels on any of the dimmable devices, everything turns on as expected (of course at the previous dimmer levels). The moment I change any of the dimmable devices to a dimmer setting, none of the non-dimmable (in this case the GE Z Wave switches) will fire. When I disable the dimmer setting for the device(s) in the scene, the switches work again.
These scenes worked fine until this week when I had to re-add one of my switches that was not cooperating. However, this issue exists on any combination of my switches and dimmable devices.
