2026 verdict
Same case, same antenna, so what does the U add?
The Smlight SLZB-06 is the one to buy for most Zigbee setups, because it is the lower priced of two nearly identical network coordinators. Both connect over Ethernet with PoE, USB or 2.4 GHz Wi-Fi, both have +20 dBm of transmit power with a +5 dBi external antenna, and both work as a Thread border router and a Bluetooth proxy for Home Assistant and Zigbee2MQTT. The Smlight SLZB-06p7U swaps the Texas Instruments CC2652P for the CC2652P7 and adds USB over Ethernet, which lets it share another USB stick, such as a Z-Wave dongle, over the network. Buy the Smlight SLZB-06 for a plain Zigbee coordinator, and the Smlight SLZB-06p7U if you want to pass a second USB radio through the same box.

What the differences mean
USB over Ethernet
The Smlight SLZB-06p7U can pass another USB dongle through to Home Assistant over the network, so one PoE box can host a second radio you supply. The Smlight SLZB-06 has no USB passthrough.
Zigbee chip
The Smlight SLZB-06 runs the Texas Instruments CC2652P and the Smlight SLZB-06p7U the CC2652P7. Both are Zigbee 3.0 coordinators and routers with the same transmit power and antenna, so for everyday Zigbee use the chip is not a difference you would notice.
Build and weight
Both share the same 160 x 26 x 22 mm case; the Smlight SLZB-06p7U is slightly lighter at 90 g against 101 g, which makes no practical difference for a box that stays put.
Which one to buy if
- you just need a reliable PoE Zigbee coordinator
The Smlight SLZB-06 does the same Zigbee, Thread and Bluetooth proxy work for less.
- you want a Z-Wave stick on the network next to Zigbee
The Smlight SLZB-06p7U can share a USB dongle over Ethernet, so both radios sit in one central spot.
- you want a unit that works the day it arrives
Several Smlight SLZB-06p7U owners received opened or wrongly flashed units, a complaint Smlight SLZB-06 owners do not raise.

What owners say
Owners of both Smlight coordinators tell the same story: moving the radio off the server and onto a PoE cable in the middle of the house is what stopped devices dropping off, and migrating an existing network worked without re-pairing. Smlight SLZB-06 owners add auto-discovery and firmware updates from inside Home Assistant and strong range from the antenna, while their complaints are the size of the case and a minority of units that needed frequent power cycling. Smlight SLZB-06p7U owners complain about the unit they received rather than the design: boxes that had been opened, a coordinator arriving with someone else's password or the wrong firmware, no simple factory reset and a web interface they call rough.
Upgrading from the Smlight SLZB-06?
Moving from the Smlight SLZB-06 to the Smlight SLZB-06p7U changes two things: the CC2652P7 chip in place of the CC2652P, and USB over Ethernet for sharing another dongle. The case, transmit power, antenna, PoE, Thread border router and Bluetooth proxy stay the same. If your Smlight SLZB-06 already runs your Zigbee network well and you have no second USB radio to share, there is nothing to gain.
Price history compared
Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.

Frequently Asked Questions
Which is better overall: Smlight SLZB-06 or Smlight SLZB-06p7U?
The Smlight SLZB-06 for most buyers, since it is the lower priced and matches the Smlight SLZB-06p7U on connectivity, PoE, transmit power, antenna, Thread and Bluetooth proxy. The Smlight SLZB-06p7U is worth it only if you need its USB over Ethernet passthrough.
What is the difference between the Smlight SLZB-06 and the Smlight SLZB-06p7U?
The Smlight SLZB-06p7U uses the Texas Instruments CC2652P7 instead of the CC2652P and adds USB over Ethernet to share another dongle. Everything else, from the case to PoE and the Bluetooth proxy, is the same on the Smlight SLZB-06.
CC2652P vs CC2652P7: does the chip change anything on these Smlight coordinators?
Not in what the two do. The Smlight SLZB-06 with the CC2652P and the Smlight SLZB-06p7U with the CC2652P7 both run Zigbee 3.0 as coordinator or router, both act as a Thread border router, and both have the same +20 dBm transmit power and +5 dBi antenna.
Do the Smlight SLZB-06 and the Smlight SLZB-06p7U work with Zigbee2MQTT and ZHA?
Yes. Both the Smlight SLZB-06 and the Smlight SLZB-06p7U work with Home Assistant through ZHA and through Zigbee2MQTT, and owners of both report moving an existing network over without re-pairing devices.
Who should buy the Smlight SLZB-06?
Anyone who wants a PoE or Ethernet Zigbee coordinator with a Bluetooth proxy for Home Assistant and has no second USB radio to share.
Who should buy the Smlight SLZB-06p7U?
Home Assistant users who want to put a second USB radio, such as a Z-Wave stick, on the network through the same box, and who are ready to check and reflash the unit on arrival if needed.
