Samsung Connect Home. Can not setup 36-302 Error
Also, if yours is a “connect home“ model, I recommend returning it, and getting one of the newer models instead. That one has been discontinued, the firmware is not being updated very often, and it will not support the same features as newer hubs.
If you intend to use zwave devices, the current hub is the one from Aeotec. Make sure you get the model for the region where you live as Z wave is on different frequencies for North America and Europe/UK.
If you don’t intend to use zwave, you could consider the less expensive smartthings station, which supports Zigbee, thread, and matter devices.
