So it is possible to set an automatic action on a scene. You can assign one or more conditions to an automatic action. If one or more of these conditions are met, the automatic action will be executed. For example, it is possible to have a plug switch on when a door is opened. By following the steps below you can easily create automatic actions yourself. In the scene overview, press the plus sign to create an automatic actions (1). You can then give a name to the automatic action (2). Add the conditions that will trigger the automatic action (3). This can be a timer or a button press, for example (4).

Please note! When only using fire protection products, it is not necessary to create automatic actions. There are also a number of standard automatic actions for intrusion protection. You therefore do not need to set these up yourself either.

Troubleshooting
If the installation fails or you encounter some other problem, please refer to this troubleshooting. It contains a number of tips and tricks that might help you further.
Installation K1
When installing the K1 system, we recommend that you pay attention to the following points.
- Make sure your phone is connected to the 2.4GHz Wi-Fi signal.
- Make sure your Wi-Fi password/name does not contain any spaces.
- The Wi-Fi name should be entered automatically during the network configuration. Is this not the case? Then you need to enable the location services on your phone and in the app's settings. Also, all permissions need to be accepted.
- Are you sure that the password for the Wi-Fi is correct? By clicking on the eye on the right, you can see the password you have entered.
- Make sure the connector flashes blue when you go through the network configuration.
- If all of the above does not appear to be the cause of the problem, then you are probably dealing with a combined WiFi band. In other words, a WiFi band that offers both 2.4Ghz and 5Ghz (in some cases, a combined WiFi band is still displayed as a 2.4Ghz WiFi). We recommend that you check the router settings to see which frequencies are offered for the relevant SSID. Before installing the system, temporarily disable the 5GHz signal and go through the installation. After installing the K1 connector, you can turn the 5GHz signal on again. If that doesn't work, you can also create a separate wifi band with a unique name and password on
2.4Ghz only. I can imagine that this is complex, we therefore advise you to contact your telecom provider for the correct settings to set up a separate 2.4Ghz WiFi band in this case, they will be able to help you the quickest and best.
FAQ
Q Can I connect a second device to my system?
A It is possible to link several phones to one connector. You can do this simply by logging in with your account on multiple devices.
Q How many devices can be connected to the connector?
A Up to 127 devices can be connected to the connector.
Q Can I add multiple connectors to one account?
A This is certainly possible. You can add various connectors by pressing the top right of the home screen. Then you have to press 'Configure your connector'. Each connector has its own set of scenes and devices and are therefore not connected to each other.
Q What is the wireless range of the system?
A All components have a range of 100m in an open space without any obstacles or interfering signals. All accessories should be located within reach of each other, as the system is not a mesh network.
