Hi @SanderRonde,
Your saying that you try to connect using a cloud connector, and are working with your own device.
Just to understand, is your device connected to the internet via an other cloud or only locally available within your network?
If you can only connect to the device in your local network, have a look at building a ZigBee, Z-Wave or Lan driver.
