I just acquired another hub (this one was expensive at $25) that came with the box & IR Blasters. It’s a:
Logitech Harmony Ultimate
Box listed number: 915-000201
#4: Hub - Labeled “Harmony” on Top
• M/N: O-R0004

• Rating: 5.15V 1A
• IC: 4418A-OR0004
• ***P/N: 815-000101
• Paired with Harmony Ultimate Touchscreen Remote
- Harmony Ultimate
• M/N: N-R0007
• IC: 4418A-NR0007

• FCC ID: JNZNR0007
Software

So it looks like it is the exact same hardware. Weird.
