I was never going to let this alone. As said above I had the tv appear and work in smartthings with a different ui to the usual Samsung 2016 ui but I couldn’t figure out how or why so some testing was needed
My findings are confusing considering what Tyler said above. Samsung connect uses a different connection method to the tv from that of Smartthings, my understanding is smartthings is cloud connection, Samsung connect is a direct local connection to some things
With that said I unplugged my St v2 hub completely, uninstalled Samsung connect from my phone and reinstalled, reset my tv to factory making sure notifications were on for new connections, echo app smartthings was disconnected from echo smart home
St is unplugged and as expected all devices are off line and no tv added by any method
Using Samsung connect I searched for devices and found among other things my tv which I am still assuming is a direct connection as the tv is not in the st app and not in the ide, back into the St software and behold my Samsung tv has appeared in the list of devices without adding it and everything else showing as off line as the Hub is not plugged in. Not only has it appeared it has a similar ui to that off Samsung connect and works fine, so my St software appears to be connecting with the Samsung connect software and connecting directly - as the hub is completely un plugged
How long this remains usable is as yet unknown, next I need to plug back in my St hub and reconnect echo smart home to smartthings
*next day update
Plugging in my St hub everything is as it should be, all devices are normal and the Samsung Tv is still there, Amazon echo smart home is re connected to smartthings BUT the Tv is not connecting to echo. There are now 4 different Tv entries in echo smart home i am guessing legacy tiles from previous attempts to get it all working again but non of them appear to work with samsung connect or smartthings and due to the poor UI and options in echo smart home the user cannot delete or reset the echo list of devices.
Interestingly or not in echo smart hub each Tv entry is listed as ( connected Via ) Smartthings and non of them say ( connected Via ) Samsung connect, which would really help troubleshoot and trace what is connected to what
The Smartthings echo skill is listed as Smartthings /Samsung Connect, if Samsung are tagging there own version of Home automation to Smartthings it would be kind of polite to add there own name to conneced devices !
having found all this and nearly made everything work again it appears that the only real option for new users of Samsung Tv
s and ST hubs is to start with Samsung connect, get everything discovered and THEN plug in and add the ST hub which should populate with its own discovered devices AND local devices which no longer use the cloud ( samsung modern Tvs )
idealy i would need to reset again and wipe my hub but honestly i really dont want too
And then i discover that the Tv has an ident with OCF in the IDE which then made me check the ide connection which said cloud and everything else in the ide says hub… give up my brain just melted OCF is supposed to help not confuse
