Communication between 2 endpoints with different numbers of endpoint

If you mean that two devices use different endpoint and you want to binding them together, it is no problem.

I have 3 devices, 2 lights and 1 switch.
Each of light device have 1 endpoint with number 8 for endpoint.
The switch device has 2 endpoint. One number is 8 for endpoint and other endpoint number is 7.
I want bind them to the lights.

Thank you.
