Input Number for custom component

Hey Everybody,

what is the best way to make a input number for a custom component? It is NOT a official component
like a sensor or a switch. I made a custom component as a binding for my installed home automation
system. And in this system they used input numbers and sliders to change the data. I do not know how to make a input problematically. I already tried it in the switch component but I can not get it to work. Here is how I tried it:

If do like the I get the following error for all other already defined input numbers:
Unable to find referenced entities input_number.alarm_clock_minute

Here is the issue on the github site:

Can somebody help me.
