ConBee II ZigBee USB Gateway Dongle and Phoscon Gateway

Dresden-Elektronik has released a new ZigBee USB dongle/stick called ConBee II (a.k.a. ConBee 2) as a direct replacement the first-generation version, as well as the new Phoscon Gateway Raspberry Pi based Zigbee Hub. Beside new Zigbee hardware, the company has also released a new version of deCONZ graphical user interface used to set up and control any ZigBee network without any programming, as well as a new corresponding “Phoscon App” mobile app for home automation control.

The new “ConBee II” ZigBee USB dongle/stick features improved signal amplifier with longer radio range, and is based on a 32-bit Arm Cortex-M0 microcontroller (Microchip ATSAMR21E18A) instead of an 8-bit AVR based MCU.

Key features:

  • Connectivity – 2.4 GHz Zigbee USB Gateway
  • Compatibility
    • Philips Hue, IKEA Trådfri, OSRAM Lightify, XIAOMI Aqara and many other Zigbee items
    • Zigbee Home Automation, Zigbee Light Link, Zigbee 3.0
  • Dimensions – 60 x 18 x 9 mm

The USB gateway does not require registration and connection to any cloud services, or even Internet access. You’ll just need to plug into a computer, laptop, Raspberry Pi, or mini PC running either Windows 7/10, Ubuntu Linux, Raspbian and Docker.

Phoscon Gateway


Phoscon GatewayFrom the outside, Phoscon Gateway just looks like a Raspberry Pi 3 board fitted in a case, but internally a Zigbee radio has been added:

  • SBC – Raspberry Pi 3 board
  • Storage – microSD card slot
  • Connectivity
    • 2.4 GHz Zigbee IEEE 802.15.4
    • Up to 200 participants can be integrated in the network.
    • WiFi + Bluetooth
    • 10/100M Ethernet
  • USB – 4x USB 2.0 ports
  • Power Supply – 5V/2A via micro USB port
  • Temperature Range – -20 °C to +55 °C

Zigbee Software and App

The Phoscon Gateway has the same Zigbee compatibility as the USB dongle, and can be controlled using deCONZ GUI that can be integrated into Home Assistant, as well as the web based Phoscon mobile app.

That’s a really steep price for an RPi with a €30 module fitted to it.

The new ConBee II hardware and firmware is also backwards compatible with the deconz serial protocol used by the previous ConBee and RaspBee, meaning that it will work out-of-the-box with the zigbee-deconz module for zigpy which Home Assistant uses for its native ZHA (Zigbee Home Automation) implementation

I guess that the steep price for the Phoscon Gateway is not the hardware or the software but that actual commercial support that you get, just as if you would buy any other commercial Home Automation Gateway (like Homey or similar), it is not just the hardware that you pay for.

Hmmm just bought Conbee USB two weeks ago and the range was weak :/

have you tried Version 1?
Was it better with Version 1?

Miki comment could be interpreted a few ways but I think that Miki meant that he bought ConBee Version 1 a couple of weeks ago, not that he bought a ConBee II (a.k.a. ConBee 2) two weeks ago. Meaning that he does not have a ConBee II (a.k.a. ConBee 2) at all, only a ConBee Version 1.

You should take into consideration that the range on almost all Zigbee devices is not long and that is why they rely on the Mesh network to repeat the signal, that is by design. Zigbee range is generally only around 10-15 meters at most for each device when you have walls and other obstacles (about the same as with Z-Wave Plus). The solution is really to buy more devices to add to your mesh. Personally, I just installed a Philips Hue Lightbuld in each of my window lights (in each window around the house) and that was enough to create… Read more »

Andreas is right, Zigbee network is made to work with mesh.
The coordinator range is low but it don’t need to access to your farthest device, but just your first router device (like a bulb or a plug for example).
