Also .. From reading the names.. It looks like you have some simple lighting rules acting on some that are also in motion lighting rules.. Is that correct?
One of these could easily be to blame for that. You might need to reset and rejoin one or all of them. Or permanently remove. Are you getting recent "Last Received" times for all of them when you look at the Z-Wave Details page? Obviously, doing a Z-Wave Repair afterward.
My gut instinct is telling me we have something looping.. Do you have any screen shots of logs when this is happening?... and can you turn on logging for the main rules that trigger during this time?
Question.... when you were creating all your rules/app automations, did you use the copy function for any of them or do alot of editing on them? (probably already been asked but just in case)
Wondering if you might be having some ghosting issues you can't even see.
well thats good we can eliminate that as a potential issue then. I saw it mentioned on another thread here and remade all my rules that felt "sluggish" yesterday and now they feel nice and responsive so figured it was worth mentioning.
