Yes, exactly what it says. I can't use my Zigbee T-4 because I have multiple racks in my home that have seperate zigbee processors. The T-4 is only capable of one ZM24 connection at once, and I have > 1.

I am going back to one way control for now. If anyone wants to make this trade you will be getting a brand new T-4 , I hope I will be getting the same.

Thanks,
Vincent
