Your smart home needs to be accessible outside your internal network in order for 1Home to work properly. The most issues are usually connected either to port forwarding or dynamic DNS.

Have you set up port forwarding correctly?

Click here to follow the WikiHow Port forwarding instructions.

If you have the ETS 5 software, you can find the instructions on how to check for port forwarding issues with UDP Ports:

  • Please open the Bus tab
  • Then click the + Plus sign under Configured interfaces
  • on the right side there will be a form: please enter a name, the individual address is empty, 
  • under server: enter your external IP,
  • Port: enter your forwarded port
  • click the checkbox: connect using Nat
  • Click the "Test" button
  • You should get the response “OK”

You can find detailed information in this article: 

Important: 1Home only suggests setting up port-forwarding of your KNX IP Interface installation for testing purposes, since there is no authentication layer included in this setup. In normal setup 1Home strongly suggests the usage of a 1Home Box which adds an additional security layer to the remote connection.

In case you would need help setting up port-forwarding or would have any additional questions or concerns please let us know through support chat or book a call.
