Spoke a little too soon. It seems better, but still a bit intermittent. Since these switches don't have any programs associated with them, and they work without the ISY communicating, I'll leave as is and hopefully won't have to update the links to them anytime soon.

In messing around with my system, I had unplugged the two range extenders on the bedroom side of the house. Now everything is working as its supposed to. I started to plug them back in one at a time, and with one plugged in the switches would communicate about half the time. With both range extenders plugged in, the right switch would never communicate. Unplugging them again brought the switch back to life all the time. Could I have faulty range extenders?

I rewired the defective switches back in the bedroom and then restored the PLM. I got an error saying that the ISY could'nt communicate with the right switch. A bit more playing around had me notice that I could turn the switches on/off through the ISY console, sometimes I'd get a cannot communicate message as below: Other times I'd get the updates pending icon as below: But now the left side bed switch works perfectly. Very frustrating. I have a range extender plugged into the outlet the switch is on, that distance is only two feet, another range extender is on another circuit about ten feet away. Try as I might I cannot get anything other than an exclamation mark or write pending icon beside the right switch. Is this looking like a wiring issue? Or wires running near something causing interference?

It's only intermittent in that after a year or so goes by, the switches loose their ability to ever talk to the ISY again, no matter where in the house I wire them. I've inspected the bedroom circuit back to the circuit breaker and the only things on it are two incandescent lamps which seldom get switched on. The PLM has no problem talking to any of the other 37 switches in the house, and some of those are very close to computers, TV's etc.. A range extender plugged into the circuit is still not able to communicate with the dead switchlincs. The new switchlincs communicate fine, I'm just getting leary of keeping #7 and 8 wired in at $50 each.

No CFL's or UPS in the house, The TV is at the other side of the house. The PLM is not a dual band but it isn't to far from a computer this year. In previous years, it was far away from any computers.

I'll leave the GFI as is, good to now know why there's one in the panel. The GFI is only eight years old. These aren't dual-band devices, but no matter what I try or where I wire them in the house once they've been a year beside the bed, I can never get the ISY to talk to them again. Doesn't seem like a range issue. I have a few dual band range extenders scattered about the house, one pretty close to these switches. And it's only switches wired to this one circuit. I've triple checked the connectors, grounds and polarity, all good. You're right in that it's a communication problem, but what might be causing it?

Yup, it's the communications that fail. If I take the defective switch and wire it in another part of the house, it still doesn't communicate. But a new one will work fine...until. I've read that other people have no problems with GFI's. I don't know why a GFI is in the bedroom, but it would be easy to replace.

I have two 2476S switchlincs, one on either side of the bed. They are not connected to any load and are only used to turn on/off all the lights in the house through their switchlincs. After about a year or a little less, they loose their communication with the ISY, though not at exactly the same time. They are still able to turn/on off the house though their scene, but I can't program anything new with them through the ISY. I've only had two other switches in the whole house fail over the past six years. The third set of these two switches have now failed (that's six in total). I don't want to replace them until I figure out whats killing them. The only thing I notice that is different on this circuit is that it is powered through a GFI circuit breaker. Does anyone have any idea where I could look for problems? What could be causing this?

All status changes are being reflected on the control panel. I've been running 3.3.10 for a while now, but as long as everything works I'm happy. Thanks again for your help.

OK, So I deleted all the scenes I created, then deleted all those devices from the ISY and then added them back. I then did a compare device links and found record mismatches on those devices, so I restored those devices. I still have record mismatches. I've also since restored the PLM, but still the record mismatch. Everything seems to work fine though.

That solved the problem. I made a scene for each switch making it the controller. Thanks for your quick help.

Here's a quick screen shot of the info you requested. But if I understand correctly, the switchlinc needs to be a controller. The switches I'm having problems with have been setup as responders only. I'm going to try creating a scene for that switch in which its a controller and then try again.

I ran the compare device links and got the results below I'm assuming this is OK? I then restored the PLM, but still have no luck. Any other thoughts?

That's a lot of conditions...... I'm wanting to test if a switch has been pressed, on or off. The if control seems to be working for that. Thanks for the confirmation.

Long ago I set up my switchlincs through the ISY and set scenes for the switchlincs to control. Everything has been working fine, but now I am trying to write some programs for the ISY and am now running into problems. The problem is that when I test for an on/off control of the switchlincs, three switches in the house get no response. When I look in the console at the state of these switches, no changes in states are displayed when I activate these three switchlincs. All the other switches in the house change their states in the console properly, just not these three. These three switchlincs activate their scenes properly, and I can activate the scenes properly from the console. I just can't seem to use them in programming a condition. Any thoughts as to why this is? I've tried restoring these devices with no luck.
