My ecosystem is crumbling!

I don’t know if this has anything to do with the edge migration or what - but my aeotec nano dimmers aren’t working properly anymore. on and off buttons on app are very intermittent on other lights (however, dimmer slider still seems to work), mesh failures during network repair…
I excluded a nano-dimmer with the hope that adding it back would make it work - now it won’t even be seen by the network at all. I simply can’t add it in any of the usual methods.
What’s going on???! My wife is about to kill me.

My hue motion sensors and aquara door sensors are acting weird starting a few hours ago, so you’re not alone.
