What (U) Means for Customers (Applies to ALL U Models)
All (U) devices include major hardware upgrades over older versions:
-
USB passthrough mode
Add an extra radio (Z-Wave, Zigbee, Thread, etc.) and use it over Ethernet/Wi-Fi in Home Assistant
→ One device can handle multiple radio protocols -
Much more memory
2.5 MB RAM vs 520 KB on non-U models
→ Better performance, more devices, future-proof firmware -
Improved Ethernet stability
New Ethernet controller for long-term reliability -
Hardware flow control support
Designed for larger, busier Zigbee & Thread networks -
Configurable Ethernet LEDs
Useful for clean installs and rack setups -
MRx(U) USB dual-radio mode
When connected to a PC, both radios appear as separate USB devices
(one cable, two radios)
