3 way SwitchProblem

[travcore]

I have two areas in my house that have three way switch configurations using Smartlinc 2476D switches. Both areas have been working fine for quite awhile. Now just the switch where the load is, is working. The other two switches cannot turn on/off the lights. The leds on those other two switches respond to the status of the lights but cannot control them. This is happening in both areas where the 3 way switches are installed. It seems to me that since both areas where the 3 way switches are installed have lost communication which leads me to believe that the issue is on the controller end instead of the switches themselves. Any suggestions? I am using an ISY99i controller.

Try a Restore Device of the SwitchLinc that is physically controlling the load.
