[DEPRECATED] - Hive (Connect) V2.6 (British Gas Hive)

Just bought SmartThings and first attempt at the Hive integration. Did all as described (easy to follow!!) - the device type and device was created and credentials input ok. However on using it, it only shows the icons but does not show any information. Also my Hive app on my phone no longer works with a message “Wrong Device Found -The device that has been installed is not supported by Hive Multizone” with a number to call - not done that yet. I had to uninstall the Device in SmartThings and then to get Hive smartphone (Android) app working again had to uninstall then install it again from Google Appstore. My Thermostat is a British Gas one and not a recent Hive branded one - they converted the app to Hive recently and all works ok.

Any ideas before I ring British Gas on the error message? Are they aware of SmartThings? Is it some sort of version thing?? Grateful for any thoughts/help!!
