[SOLVED]A few Insteon devices not responding

All of the sudden a few of my Insteon devices have stopped responding. Two of them are appliance linc modules and one is a toggle switch. If I move the appliance link to a different location in the house it responds. So I am thinking it is some interference or something similar. Any suggestions on how to troubleshoot. The other 15 device or so are working fine

[MODERATOR NOTE] moved to the appropriate fourm.

Check out the signal troubleshooting page for tips on dealing with signal issues. I'd start by focusing on other things that are on the same circuit(s) as the ones that are failing since you have a bunch of others that are working.

Finally located a bad cfl bulb. Problem resolved
