Well I thought I would update that the good news is that somehow my support enquiry managed to get through to Samsung support and the super helpful Fiona (I think the same lady that helped you Graham on this thread) came back and has helped resolve my Hub pairing issue
The problem was as suggested that the Hub was still paired to the old user’s account so I needed to do a full factory reset to get the device to re-register with my account, and even though I had gone through the process with the flashing yellow, and then solid yellow lights - the part I hadn’t got correct was to immediately release the reset switch as soon as the hub light goes to solid yellow
This was the detailed response from Fiona
Thanks for providing the pictures of the Hub serial number. Checking on our end, the Hub is still attached to the previous owner’s account so that is the most likely reason you’re having trouble adding to your account. You’ll need to factory reset the Hub before it can be activated again. Here are the steps:
1. Disconnect the power cable and remove the batteries from the Hub
2. Using a pin or a small tool, hold down the reset button on the back of the Hub
3. While continuing to hold down the reset button, replace the power cable
4. Continue holding the button for more than 30 seconds
5. When the LED on the front switches from flashing yellow to solid yellow, release the button
6. Reinstall the batteries into the Hub
If you do not release the button within a few seconds after the LED switches to solid yellow, the Hub may not begin the reset. The Hub will take 5-10 minutes to fully factory reset. Once the LEDs on the front of the Hub turn solid green, you should then be able to add the Hub in the app using the Welcome Code you have
And then the even better news is I managed to get my Zigbee thermostat connected to my hub using a combination of the search for device and these very cool beta drivers from @Mariano_Colmenarejo - thanks Mariano these work perfectly with my Centralite 3-Series Pearl ZigBee Smart Touch Thermostat
