Hi
I know this is the wrong place but it is extremely difficult to contact Smarttings. I have a smartthings hub which will not connect for a reason at your end i think.+
This forum was created a number of years ago so that customers could help other customers with ideas and questions about the home automation platform. It’s not an official support channel and it’s not monitored by smartthings staff except for spam and harassment. So it’s not going to help get you in touch with any smartthings employees.
It can be frustrating, but the best thing is to use the official support channel at the bottom of the following page:
If that doesn’t work, try posting on the Facebook page. At least that one gets read by Samsung employees, although they may be in marketing.
I wish we could help you more, but we’re just other customers.
Yes they are definitely UK hubs. I used to use Z-Wave.
You’ll see the same serial number on Amazon UK and eBay for many items. Googling around it seems people have been baffled by the model number for years. I think the Z-Wave chip on the label (ZM5304AU) might also be a North American one.
As my first hub came out of a kit in 2018 I was surprised it wasn’t the second gen V2.
Update: This is from the User Manual lodged with the FCC for R3Y-STH-ETH200.
Note the last line CE version contains M/N: ZM5304AE.
