Radar RTL 511

I have already tried this. I called the support earlier. This is a known issue. 

Is that specific to the 511? I had the same issue on my 510 and had just done exactly what aweatherall describes and it paired correctly.

I just tried it again. It just does not work. The Edge finds both, but only connects to the radar sensor. Both are displayed in the Sensor Menu, but a connection is established only to the Radar Sensor.

Are you selecting both from the search or just the light?

I search only the light and add this. Then he automatically adds the radar sensor. 

The new firmware 3.50 does not fix the problem yet.

both are in the list of sensors, but he connects only to the radar 

I have tried it several times. I reset the radar and then added both or just the light. it just does not work.
