Start fresh with Zwave 800

Something happened about a week ago where my zwave, that has always been less than ideal with the 700 dead nodes, became unusable. 115 devices and most all of them are offline and if they show online, as soon as I try to interact with them I get a failure error and they go dead. Using ZwaveJS.

I picked up an 800 stick (not sure it will be better with the random dead nodes) as I decided to just start over and chuck the 700.

What is the appropriate way to start fresh?

Any suggestions here? I tried to excluded one device today and it didn’t work so I am not sure if a manual exclusion of all devices will be an option.

Since that isn’t working is it simply a matter of removing zwavejs, the zwave integration, reinstall with the 800 stick and exclude/include all the devices on the 800 stick?

I reverted to a backup from 3/14 earlier today and the zwave network worked great for a few hours but now it’s back to all dead (didn’t take any updates).
