I recently purchased a ADT Panel and already am running a separate Smartthings Hub v2. I only have my ADT sensors connected to my ADT HUB and everything else connected to my Smartthings Hub. No issues at all. See both hubs in my Smartthings App. Also running Smartthings Home connect in Wifi mode only. Plan on switching over to smarthings WIFI soon due to home connect not having a firewall. Anyone having issues with the new Samsung WIFI mesh system. Currently have 32 devices connect to both huds.
