I've noticed that most of my automations do not work the first time they're executed after a hub reboot. Second time, they do run. For example, my "double tap down to set dimmer to 25%" Rule Machine 5.1 app. It works fine until the hub reboots. Then, no matter how long after the hub reboot, the first time I double-tap, the light doesn't turn on/get set to 25%. I double-tap a second time and the rule executes as expected.
I've checked for z-wave ghosts, and there was one, but removing it hasn't fixed the issue. It happens on switches of various brands (GE, Zooz, Inovelli), so maybe this has something to do with the hub.
I've searched, and most results are for issues where rebooting the hub is the solution to an issue with the automation itself--that is not the situation here.
Has anyone dealt with something like this?
