There is no model by that name. GE and SmartThings do not have a co-branding relationship. They are two separate companies.
The only smartthings branded devices are the hub, some sensors, and one plug-in pocket socket. All of those use the zigbee protocol.
The GE devices are actually made by Jasco. They make zwave, zigbee, and Bluetooth switches. These all use the same outer case, so they look identical, which is one reason we need the model number.
GE zwave Switch (14294):
GE zigbee Switch (45857):
Beyond that, there are both Z wave and Zwave plus GE branded switches and again they look identical. That’s the other reason why we need the model numbers. The pairing options are somewhat different.
Do all SmartThings devices repeat?
With the exception of the hub and the pocket socket the smartthings branded devices are battery-operated zigbee devices. Zwave repeats only for Z wave, zigbee repeats only for zigbee, and most battery operated devices don’t repeat at all. So the SmartThings branded devices other than the hub and the pocket socket do not repeat. The pocket socket will repeat, but only for zigbee.
Most zwave mains powered devices with the exception of smoke sensors do repeat—But again only for Zwave.

I’ll be staying at his place this weekend. I was planning on taking a 100’ of network cable and an extension cord so we can play with the hub placement.
That sounds like a good idea. Remember that even if the devices were bought brand new, some of them may need to be excluded before they will pair. It’s just something to be aware of, and usually the first troubleshooting step we take, just to get it out-of-the-way.
