Support FAQ

What do I need to use the interfaceGO NK8?
You will need a Universal Devices ISY-series home automation controller, running firmware 2.7.6, attached to your wifi network.  You will also need a Nokia N800 or N810 (available with the NK8 in a bundle) running OS2008, and a supported lighting control system (currently Insteon).

What are the requirements for the configuration utility?
The configuration utility requires a PC running Windows XP, Windows Vista, or Windows 7, with the latest version of Java installed.  Minimum screen resolution is 1024×768.

What type of lighting and thermostat controls does the NK8 support?
Since the NK8 software controls your lighting through the ISY series of home automation controllers, the software supports just about anything controllable by the ISY-26 or ISY-99.  The Universal Devices ISY currently supports Insteon.

What type of security system does the NK8 support?
The NK8 software arms and disarms your security system through the ISY series of home automation controllers, which currently supports the Elk M1.

What types of webcams does the NK8 support?
The NK8 will take a still image from a webcam, from a URL you specify, and refresh the image approximately every 5 seconds.  The following webcams have been tested successfully:

- Panasonic BL-C1A  - Panasonic BL-C111A  - D-Link DCS-2100+  - D-Link DCS-5300G

Other webcams that provide a still image URL may work as well.

Why can’t the NK8 connect to my webcam?
Please be sure the URL you are providing to the NK8 works in your web browser.  The NK8 requires a “clean” connection to your web, with no username, password, or browser plug-ins required.  The URL you specify should go directly to an image form your webcam.  Here are some sample URLs:
Panasonic Still Image:×240
D-Link Still Image:

What type of electricity meter does the NK8 support?
The NK8 software views realtime electricity use and pricing through the ISY series of home automation controllers.  The ISY currently supports the Brultech electricity meter.

Does the interfaceGO NK8 also run on the Nokia 770?
The NK8 will NOT run on the Nokia 770.

Which memory card slot on the Nokia N800 does the config file and license file need to be stored on?
Please be sure to store your config file on the memory card located in the slot on the BOTTOM of the Nokia N800 (behind the pop-out stand).  With NK8 version 1.2.2 or higher, the config and license files can now be located in the Nokia’s N810 internal memory.

Why does my Nokia lose its connection to the ISY?
Since the NK8 is in constant communication with the ISY, a reliable wifi network is required.  Please make sure you have good wireless range in the areas you’re using the NK8, and that you have no interference from other devices (2.4 Ghz phones, baby monitors, etc.)  If a disconnect is detected, the NK8 will do its best to reconnect without the user even knowing it.  On a reliable wifi network, however, disconnects should be very rare.

Why is the time wrong on my NK8 software?
Be sure that the time and ‘home city’ are set correctly on the Nokia – check the Date/Time control panel application.  Also be sure that you are creating your config file from a PC set to the correct time zone.

Why am I getting the error “Operation Failed” when trying to install the NK8 on my Nokia?
Be sure you are running OS2008 on the Nokia.  The NK8 software will NOT run on OS2007.

Why is the NK8 Config Utility not running on my PC?
Be sure that you have the latest Java (currently 1.6) installed from

Can I run the NK8 Config Utility at the same time as the ISY’s Administrative Console from the same PC?
Yes.  With ISY firmware 2.6.5 or greater, and the NK8 v1.2.1 or greater, you can have multiple simultaneous connections to your ISY per PC.

Why isn’t the NK8 Config Utility downloading the list of devices & scenes from my ISY?
The Config Utility uses UPnP to connect to the ISY and download the list of devices & scenes.  If they are not showing up, be sure you are typing the correct username and password for your ISY, and be sure that you are able to establish a good UPnP connection with the ISY.  If the ISY’s Admin Console will not connect to the ISY from your PC, neither will our Config Utility.

Why am I getting a ‘LICENSE ERROR’ on startup?
Your NK8 software must be activated before using.  If you purchased your Nokia direct from us, your order came with a “license.lic” file.  If you have not yet received your license file, please contact and provide us your activation code (displayed on-screen).  Once received, the “license.lic” file must be copied to the root folder of your Nokia’s memory card for the NK8 software to run.  Be sure your Nokia is NOT connected to your PC when launching the NK8 software, and that your Nokia is connected to your home wifi connection and able to reach your ISY’s HTML page.

What is the Nokia’s expected battery life?
Battery life will vary dramatically depending on screen settings and type of use.  At default screen settings, our experience on an N800 is that a full charge on a new battery will last for 20-26 hours of typical use, running the NK8 software full-time.  This is with wifi enabled, but Bluetooth disabled.  Of course, the Nokia can always be left plugged in via its included AC adapter.   

Is there a way to adjust or disable the Nokia’s screen saver?
Under the Nokia’s Control Panel, under the Display option, you can configure the amount of inactivity time before the screen saver activates.  You can also configure the Nokia to always keep the screen on when charging.

Can I control my lighting with the NK8 software through the internet?
Yes, the N800/N810 can be configured to control your home from any wifi internet connection – as long as your router and ISY are configured to allow external access.  The NK8 currently supports HTTP access only – it does not support HTTPS.  In the Config Utility, be sure to choose the “IP” connection method and fill in the appropriate fields.  Please keep in mind that an HTTP connection is not encrypted, so use this connection method at your own risk.

Why can’t I connect to my ISY over the internet?
Make sure you are connecting via “IP” mode.  Be sure you have the ISY configured for access via the internet.  Be sure you have the ‘Host’ value typed in correctly (  Be sure you have the ‘UUID’ typed in correctly (uuid:xx.xx.xx.xx.xx.xx).  You can find your UUID on the HELP, ABOUT window of the ISY’s Administrative Console.  The NK8 will NOT work over an HTTPS connection.

Is there any way to reduce the amount of time it takes for the NK8 software to load on my Nokia?
Yes.  If your ISY has a static IP address, try using the NK8′s IP connection mode instead of UPnP.  This is done through the NK8 Config Utility, and instructions are in the documentation.  This will reduce the amount of time it takes for the NK8 to locate the ISY on your LAN.  

Is the interfaceGO NK8 for Nokia compatible with the NK8-PC application?
Yes.  Because both software packages share the same configuration utility, a layout created for one application will work with the other.
