Frequently Asked Questions

 

 

 

 

01

First Steps

 

How can I make Houseinhand KNX recognize my home?

Houseinhand KNX needs two files to recognize your home. These files are the configuration file (cfg extension) and license file (hih extension). If these two files are already transferred to the app, the only thing that may be configured is the network settings. To access network settings go to iPhone/iPad built-in settings app and search for Houseinhand KNX.

What devices can I control with Houseinhand KNX?

With Houseinhand KNX you will be able to control almost all KNX devices like lights (simple, adjustable and RGB), shutters (simple, with position control or even Gradhermetic® and Velux®), climate (set-point, KNX climate mode and temperature viewers), weather stations (rain, light and temperature viewers), central functions and KNX scenes, IP cameras, audiovisual devices, and video intercoms. It also has, two generic widgets (1bit and 1Byte) that allow integrating almost everything else that has not a dedicated widget.

Does Houseinhand KNX require extra hardware to work?

Houseinhand KNX connects directly to any KNX IP gateway or router. So it does not need extra hardware or servers.

I have transferred the cfg and/or license file but nothing happens.

For the changes to take effect please close Houseinhand KNX from the multitask bar. To do that, double-click the iPhone or iPad home button, and the multitask bar will appear. Then, long tap on Houseinhand KNX icon until it starts shaking. To close it press the little red button in the upper left corner. The next time you launch Houseinhand, it will load the files you have transferred to it.

What steps do I need to follow to try the demo version?

First of all download Houseinhand KNX from the App Store and Houseinhand Designer from www.houseinhand.com/downloads. Then create a .cfg file with up to 6 widgets using Houseinhand Designer and transfer it to your device as explained in the manuals. No license file required.

Is Houseinhand KNX v1.x compatible with iOS7?

Apple’s new iOS7 operating system includes important changes that make the current Houseinhand 1.7 and older versions not working correctly.

We hope our new version of Houseinhand 2.0 will be available even before iOS7 release, but if that is not the case if you have Houseinhand v.1.x installed on your mobile device, we recommend you to wait before upgrading to iOS7 until Houseinhand 2.0 is available, otherwise, you will not be able to use Houseinhand 1.x on iOS7.

The upgrade from Houseinhand 1.x to Houseinhand 2.0 will be fast and will only require a simple user registration. We will inform you in detail shortly of the whole process.

Connections

 

What is “Autodiscover IP”?

Houseinhand KNX needs to know the KNX IP gateway or router IP address to connect to it. This can be done two different ways. It is possible to enter it manually or to tell Houseinhand to find this IP address by itself. If auto discover IP is enabled, Houseinhand KNX will search that IP address and then connect to it. Otherwise, it will use main IP or alternative IP depending on the main IP switch. Autodiscover IP is only recommended when connecting from inside the local area network.

How can I connect from outside my home?

Houseinhand KNX allows to connect to KNX installations even from outside the local area network. There are two different ways to do that. The first one is setting up a VPN (virtual private network) on the iPhone/iPad. This way, the communication is encrypted and Houseinhand KNX will connect to the KNX IP router or gateway using its private IP address. (this IP address must be configured manually in Houseinhand KNX settings, auto discover IP function will not work) The other way is using PAT (port address translation)

What do you recommend when connecting from outside? VPN or PAT?

For many people, PAT (port address translation) is easier to setup than VPN (virtual private network) connections. Also, some ISP (Internet service providers) block VPN connections. Houseinhand KNX will work with these two methods but we strongly recommend VPN because of its encryption. It is the safest option.

Why PAT is not working when connecting over 3G/2G but is working when connecting to WiFi?

It is a known issue that some mobile ISP (internet service providers) are blocking PAT. It is not a Houseinhand KNX issue, it will happen with every service that needs PAT to work. The solution may be using VPN or change your ISP.

What is “Gateway type”?

Not all the IP routers and gateways work the same way. They interpret KNX protocol differently in some situations. Sometimes, a connection error will appear after 30 seconds of launching Houseinhand KNX despite it has been successfully connected to the KNX IP router or gateway. In this case, you must change the gateway type switch and this error will disappear.

Which IP routers and gateways are compatible with Houseinhand KNX?

Houseinhand KNX is compatible with KNX protocol so it should be able to connect to every single KNX IP router or gateway that is KNX compliant. Despite this, not all KNX IP routers or gateways interpret the protocol the same way. To solve this problem, a switch called gateway type has been added to the Houseinhand KNX settings.
If there is no need for a KNX IP router, it is recommended to use a KNX IP gateway because it is cheaper and is enough for Houseinhand KNX. Some compatible KNX IP gateways are JUNG IPS 100 REG, SIEMENS N148,…

Will Houseinhand KNX switch to alternative IP/Port if main IP/Port can not be accessed?

No. Houseinhand KNX will connect to main or alternative IP depending on main IP switch. If it is enabled it will connect to main IP, otherwise to alternative IP.

 

 

 

 

03

Multimedia devices

 

What do I need to control a multimedia device?

Houseinhand KNX needs extra hardware to connect to an IR controlled multimedia device. Specifically, it needs an IP to IR gateway. At the moment, Houseinhand KNX is compatible with these IR gateways:

Global cache (http://www.globalcache.com):

  • GC-100
  • iTach WiFi to IR (ref WF2IR)
  • iTach IP to IR (ref IP2IR)
  • IP to IR with POE (ref IP2IR-P)

IRTrans (http://irtrans.com). Only models with database (-DB reference):

  • IRTrans Ethernet
  • IRTransEthernet POE
  • IRTrans WiFi
  • IRTrans LAN I/O (nomes Ethernet, NO RS232)
  • IRTrans LAN Controller (nomes Ethernet, NO RS232)
  • IRTrans LAN Controller XL (nomes Ethernet, NO RS232)
  • IRTrans LAN Controller XXL (nomes Ethernet, NO RS232)
  • IRTrans LAN Controller Multistream 16 (nomes Ethernet, NO RS232)

Which IP Cameras are supported in Houseinhand KNX?

Houseinhand KNX has two IP camera dedicated widgets. One for Mobotix IP cameras and one for AXIS IP cameras. These two widgets have video quality control so depending on the connection speed, the user can change between low, mid and high profiles. Some integrators had luck using one of these widgets with other brand IP cameras.

Which multimedia devices can I control with Houseinhand KNX?

Houseinhand KNX can control almost all IR controlled devices using IRTrans and Global Cache.

 

 

 

 

04

Licensing

 

Can I test Houseinhand KNX before buying?

Yes. It is possible to control up to 6 Houseinhand KNX widgets without a license. The only limitation is that when connecting from outside the local area network (for example when connecting to your house from work) it is only possible to see devices status but not control them. (for example, you can see the room temperature but not change the set-point). Once the license is attached, these limitations will disappear.

What is an additional license?

The additional licenses were created to reduce the cost of Houseinhand KNX licenses when having more than one iPhone or iPad at the same home because each license is only valid for the device it was done for. For example, for a house with 4 iPhone and 2 iPad, you need 1 Conventional License for iPhone, 3 Additional License for iPhone, 1 Conventional License for iPad, 1 Additional License for iPad. For ordering that kind of licenses, it is needed to provide the KNX IP router or gateway MAC address.

If I want to control more than one KNX installation can I buy additional licenses?

As explained before, the additional licenses are attached to a KNX IP router or gateway MAC address, so in this case, conventional licenses must be used.

What would happen with my license if my device gets lost/stolen/damaged?

The licenses are unique for each device, so if you get a new device you should get a new license. In the case the device has been replaced by Apple, we will give you a new license for free. In the case that the change is due to an upgrade or stolen device we will give you a new license for free but there is only one free change per year.

Will the actual licenses work with future versions of Houseinhand KNX? Yes.

05

Customizing

 

What are the environments? How can I create one?

The environments are some scenes that are configured by the end user for everyday situations. For example “I’m working” or “family dinner”. It is explained how to configure them in the user manual.

How do I change my background pictures in iPad app? It is explained in the user manual.

Is it possible to use custom icons? No.
