Add multiple light sources (hyperion and zwave)

I had a simple domoticz setup running, but could not get it running the way I wanted. This weekend I installed Home Assistant and got it up and running.

The problem I have now is that my two Zwave dimmers are found with the autodiscovery. I have a diy ambilight with Hyperion. When I add the hyperion lightning to the configuration.yaml I lose my two zwave dimmers.

Can somebody tell my how I add my zwave.dimmers to the configuration.yaml file ?
