My hub is on 1st floor and have 2 intermatic ca600 switches , one on 2nd floor and other in basement. The one in basement is close to hub than one on 2nd floor.
I could pair the 2nd floor switch without moving the hub. But for paring basement switch I need to take hub closer to switch. Now ater I put hub on 1st floor on it’s original location the swtch in basement does not respond to commands evern though it is closer than 2nd floor switch. I tried swappng both swithes , stil one installed in basement does not work. Have no idea what is the issue. If take the hub with in 10 ft distance then it starts working. I even put a repeater switch closer to basement CA600, but no success.
Only difference is basement lights are small halogen bulb like this one http://www.homedepot.com/p/Philips-50-Watt-MR16-Flood-Light-Bulb-3-Pack-415802/202783079#.UdLM7_mPPXI
If halogen bulbs were issue then taking hub close should not work. I dont understand what is the issue.
