D-Link DCH-G020 A1

The DCH-G020 was advertised as a “Smart Home” controller for Wi-Fi and Z-Wave based devices.

The stock webinterface has no functionality besides upgrading the firmware (IP address obtained by DHCP). There is also a hidden page /zwave.htm, but it would not allow you to do anything useful with the device without the “mydlink Home” app and cloud service (users report even that will only let you control those few Z-Wave devices that are available from D-Link).

Qualcomm Atheros QCA9531 @ 650 MHz 64 MiB 16 MiB 2x 10/100 2×2 bgn 1x 2.0 Yes ?

Supported since version 20.

The factory image can be flashed using the regular Web UI, the IP address will be obtained by DHCP (default 192.168.0.60).

Login as admin with the 6-digit Pin Code from the bottom label as password.

If flashing does not work, try a different browser or flash via uboot httpd:

The Recovery Web UI (pressing reset during power on until led flashes red) has problems with modern browsers; try chromium-based or upload with

SigmaDesigns (now acquired by Silabs) SD3503A-CNE3 USB Z-Wave Plus Controller (enumerates as ttyACM0), including 32KiB EEPROM

Genesys GL850G USB 2.0 Hub, one port accessible from outside, one connected to SD3503A, one internal 2mm connector should allow for adding additional devices, e.g. flashdrive for extroot or some CC1101 RF-dongle etc. (there's plenty of space left within the cylindric case)

Pericom PT7C-43390 I²C Real-Time Clock, CR2032 backup battery

PCA9554A 8-bit I²C I/O Expander, seems to be used for controlling the USB Hub (but there's also space reserved for several additional passive componets and a SOIC-8 IC nearby on the pcb)

Todo: find further pin assignments, maybe also interrupt pin to host?

Remove the two larger rubber feet left and right to the bottom label to expose the screws. Squeeze the cylindrical part of the case while pulling it off, and be extra careful with the WPS button cap, especially when reassembling the case.

port.serial general information about the serial port, serial port cable, etc.

UART is on JP1 (near the right of the backup battery), 115200 8N1

Pin1 GND
Pin2 TX
Pin3 RX

stock uboot supports tftpboot and even httpd to upload flash image, but only md to backup the flash.

sending md 9f000000 4194304 to uboot will hexdump the whole flash to the console, this takes about 1h 40min.

capture the output of the terminal to a file and make sure to remove the first line (echo of the md command that was sent),

then use xxd -r to convert it back to a binary file.

there seems to be no crc32 in uboot, so better do this twice and compare the results…

port.jtag general information about the JTAG port, JTAG cable, etc.

How to connect to the JTAG Port of this specific device:
Insert photo of PCB with markings for JTAG port

Press Enter on the serial console after booting, login as root with password whatsup

starting httpd will listen to 192.168.0.60, this might be equivalent to the second recovery method described by dlink:

ftp://ftp.dlink.de/dch/dch-g020/documentation/DCH-G020_howto_reva_Recovery_en.pdf

you're supposed to upload a special recovery firmware there first, and only then upgrade to the latest version.

To start using this device for home automation via z-wave, we first need to move the overlay filesystem to a USB drive, as the packages Domoticz and openzwave would be too big to fit into 16 MiB flash.

Extroot Configuration

See extroot configuration for detailed installation instructions.

USB Mod (add two more ports)

Instead of wasting the precious external USB port, you can choose one of the unused ports from the internal USB 2.0 Hub:

You will have to add 22 Ohm resitors for the USB lines. For most devices it should work to connect VBUS directly to 5V supply of the router, but keep in mind this way you could not easily reset an attached USB device by power cycling.

One of the USB ports is on J8:

Pin1 (sqaure pad with arrow) 5V
Pin2 GND
Pin3 D+
Pin4 D-
Pin5 VBUS, n.c.

You could add yet another USB device on the U21 connector, of course.

dch-g020_usb.jpg

Remember, there's no need for this to look sophisticated when everything will remain hidden inside the case :)

dch-g020_extroot.jpg

Installing Domoticz

Now that we have increased the storage, we can proceed to

opkg update && opkg install domoticz openzwave

Domoticz will run under a new user named domoticz. To enable access to the Z-Wave controller, we additionally need to add that user to the dialout group. This can be done desktop-style by installing the usermod utility:

opkg install shadow-usermod
usermod -a -G dialout domoticz

or by manually editing /etc/group and just appending the username to the dialout group, e.g.:

dialout:x:20:domoticz

with 20 being the group id for dialout.

Now you can reboot the router and access your new Domoticz installation on port :8080.

The portal will greet you with a welcome message suggesting to add your hardware now, thus click Hardware.

Choose a name for your adapter, e.g. DCH-G020 built-in Z-Wave, select Type: OpenZWave USB and the Serial Port: /dev/ttyACM0

After adding the device, it will take a few seconds for the OpenZave manager to startup and configure the device. Click Update to check, and finally the “Setup” button when it has changed from brown to blue.

If you had previously paired any D-Link devices with the hub, it might be a good idea to hit Node Management → Hard reset controller now, before including your first device. See the manual for the devices for information about the hard-reset procedure (just starting exclusion mode / new inclusion might not work when the devices were previously paired to the D-Link cloud, so it should be a good idea to start from scratch.

Todo: make sure domoticz config will be preserved after reboot

See the Domoticz wiki for further assistance on setting up your devices.
