ZWave control stopped working completely - although Power status works

Thanks for the advice. I've been through the rebooting/poweroff for 30 mins sequence a cpuple of times already without any differences.

I was already at the latest version, and rolling back to 2.2.2.129 did not help either.

I'm beginning to suspect it depends on the time of dsay (crazy!) - it stopped working at about the same time both days. I know, it seems crazy, but I'm running out of ideas...

[Oh yes, another fact: I've built my automations with the Button Controllers if that matters?]

As to buying a UZB-7 and delete ghost nodes: I googled a bit, and it looks to me like a) they are visible in the UI, and I can't see any, and b) C-5 should delete them automatically from the stick. Remove Ghost Nodes

If I want to go that route, I have two questions: a) what software should I use with it? and b) I already have an Aeotec Z-stick Gen5 - could I use that instead?
