Farewell! May the knives we're throwing at your back all miss! ;^)
Long ago I suggested that WW skip making hardware, and instead reprogram other folks hubs to add the WW Special Sauce (rule infrastructure).
WebCORE is an awesome piece of work, despite being at only its 1.0 release. I'm somewhat concerned that Samsung didn't do this, that it was done 100% by the SmartThings user community.
Please let us know how it goes, bumps and all.
Edit: As for your devices, I believe a Factory Reset for each is all that's needed.
