All of the overhead lighting in my house is controlled by Jasco Z-Wave motion dimmers. I have webCoRE PIstons that tell the light to turn on when motion is detected. They're very basic actions with no restrictions except for location mode (they don't turn on if mode is "night"). 95% of the time they work perfectly, but every now and then I will enter the room and nothing happens for 5-10 seconds and then the lights will come on. It will happen with several lights at once, too. For instance, if I walk down the hallway to the bathroom, the hallway light and then the bathroom light should turn on. Neither will turn on. About 5-10 seconds later, both will turn on at the same time. The logs in webCoRE and in Hubitat both show everything working correctly as far as device states, sent commands, etc. Nothing seems out of the ordinary there.
What I have confirmed during troubleshooting is that there are no ghost nodes. The Z-Wave mesh looks solid. I've also confirmed that the hub is not using too much CPU or RAM when this happens. It's almost like the thing just goes to sleep and needs to "wake up" before it sends commands.
This is only mildly infuriating, but I'd like to sort it out. Does anyone have any suggestions on what might be happening or how I can troubleshoot it further? Thanks.
Update - this had quit happening for several months, but started happening again after a recent update.
