Velleman
What can you do with Velleman and Niko Home Control?
If you connect the contacts in your doors, gates and windows to Niko Home Control, you can check whether they are open/closed via the Niko Home app on a tablet or smartphone, the Touchscreen and/or Digital black.
We recommend the following options to make even better use of this connection:
Receive a notification when a door is opened while your home is in away status; see Creating notifications
Automatically switch on lighting when you open the door; see Custom routine
Temporarily stop heating/cooling when a window is open; see Creating a condition

Niko requirements
Your Niko Home Control installation meets the following requirements:
It has a wireless smart hub or a connected controller II.
It is configured with the most recent programming software.
Depending on the basic modules of your Niko Home Control installation, you need to install the following additional products:
Required additional products | Reference numbers | |
---|---|---|
Connected controller | Digital potential-free sensor module with one free input per signal that you want to use in Niko Home Control If the output contact on your third-party device is not potential-free, you need an additional potential-free contact module (e.g. Finder 22.32.0.230.1xx0 for 230 V connections, Finder 22.32.0.012.1xx0 for 12 V DC connections, Finder 22.32.0.024.1xx0 for 24 V DC connections) | |
Connected controller with a wireless bridge | Connected (double) switch with one free input (E) per signal that you want to use in Niko Home Control If the output contact on your third-party device is not 230 V, you need an additional 230 V contact module (e.g. Finder 22.32.0.230.1xx0 for potential-free connections, Finder 22.32.0.012.1xx0 for 12 V DC connections, Finder 22.32.0.024.1xx0 for 24 V DC connections) The connected (double) switch can be placed on a DIN rail using a modular holder (e.g. Legrand 412950) | |

Programming
Check if your door or window contact is normally open or normally closed. Adjust the feedback text accordingly.
Configure the potential-free sensor module or connected switch and use its signal to show the status of the door or window via the Niko Home Control programming software.
In case of bus wiring
Create a connection to external system.
Create a player status:
In the behaviour, select the connection to external system.
In the parameters, you can enter the text that will be displayed as feedback.
In case of traditional wiring
Assign the push-button extension to the extension button input (E1) of the connected switch.
Set the operating mode of the push-button extension on “push-button mode”.
Create a virtual device.
Link a basic action between the push-button extension and the virtual device.
Create a player status.
In the behaviour, select the virtual device.
In the parameters, you can enter the text that will be displayed as feedback.
