For some unknown reason, my ISY994i can no longer communicate with 1 of my INSTEON dimmer switches. It shows up in the Admin view with a red ! point and a pop up says it cannot communicate with the device. The switch works manually. I have rebooted my ISY but that didn’t fix it. Is my switch bad? Suggestions on fixing? Thanks.

Right click on the switch and pick restore device. If that doesn’t do it, do a factory reset followed by restore device.

 

If neither one of those does it, it’s most likely dead.

I tried restoring the device last night too which didn’t work but I didn’t do a reset on it first. I’ll try that. Thanks.

Well factory reset didn't work so I replaced the switch with a spare I had.  The new switch is working.  Have others had the INSTEON communications part of a switch go bad but yet still have the manual operation of the switch still work?

Yep.  I've replaced a couple with this issue -- one switchlinc that wasn't too painful, as it truly was ancient, but I also had a bad KPL and that hurt (much more $$ + it was just out of warranty period...)

I had an OnOff Module (plug-in for humidifier) randomly send out a Scene On code when operated, instead of an 'On'  ACKnowledgement.

 

A simple power cycle cured that one, after months of sleuthing a phantom "All On" with some recognisable pattern intelligence.

I had some earlier hardware ones with the opposite issue.

Local Buttons did not work but the control communications where fine.

Smarthome had an issue with the small tact switches the buttons activated.

They extended the warranty on that run of hardware to seven years.

Good to know.  I'll send them an email and ask.

OK.

Though the SwitchLincs we where talking about where the old 2476S/D power line only ones and in 2007 if my memory is correct.
