Hello.

Today I've noticed event viewer being flooded with messages :

I have narrowed it down to to communication with 2477S Dual Band SwitchLinc.

The messages only show up when switch is set to OFF.

Would that indicate problem with PLM or the switch?

I do have sporadic communication errors with other Insteon devices.

It's possible the link tables in the switch got corrupted. Try doing a factory reset on the switch, then a restore device

Being that you have comm issues, they could be caused by noise on the powerline, a poor insteon mesh network, or a defective device.

Do you have X10 devices currently installed

How many Insteon devices do you have installed

In HELP | ABOUT, what is your firmware and UI versions

@Techman I do not have any x10 devices.

I have 37 Insteon dual band devices ( not counting battery ones).

My Eisy is on v6.0.0 same with UI.

This X10 message only show when switch is turned either with off command or turned off by a scene ( motion sensor ).

Reset and restore didn't help.

Link tables match.

When I disable switch in AC and operate switch locally (physically pressing on-off) message doesn't show up.

Take a look at this link. Being that you don't have any X10 devices and the fact that you have comm issues I would think that you have some type of noise on your powerline. Do you have a UPS or other electronics installed near your PLM? Do you have any battery powered motion sensors installed?

@tibbar

Alkso take a look at these links

Mystery X10 codes - help to find source - ISY994 - Universal Devices Forum

X10 log events, no X10 devices - ISY994 - Universal Devices Forum

Yes I've read the thread.

Yes I have UPS on different circuit.

I have multiple motion sensors.

Message just appeared today.

If it was a noise why today and why only after PLM sends OFF command to switch?

It could be a combination of the off signal from the switch and noise from another device.

Some things to check/try

Put your UPS on a Filterlinc as they are notorious for creating powerline noise issues

Check the batteries in your motion sensors, a low battery can cause insteon issues

If you have any battery/phone chargers plugged in, unplug them.

J/Status Request in X10 signaling is all ones. 11111111. It sounds like noise to me also.

I don't have any Filterlinc.

I'll be at this for a month

For now I've disabled one switchlinc in Administrative Console =no more X10 messages.

This is what you need for the UPS, originally it was called a FilterLinc

Powerline Noise Filter – Insteon

It's also possible that the SwitchLinc is defective and creating the noise, do you have another one you could replace it with?

@Techman I'm going to order couple of FilterLincs.

I have more switches, going to change it and see how it goes.

Always something :( .

But if it is noise why appear today?

Long thread... but if it only happens when the switch is off, it's pointing to the switch. Some older insteon switches have the ability to receive and send x10. Insteon switches can also be "confused" after long periods (years) of operation.

I'd try this if it wasn't in all of the other great suggesitons:

• Turn the switch off and confirm the messages continue to come

• Pull the air gap tab out on the bottom of the switch.. did the errors stop?

• If Yes.. Factory reset the switch and do a restore device

• Test again

One more thought. If they are the original 2476S on-off relay models. They do not have an Air Gap switch and used a convoluted way to factory reset them. Easy way to tell. If pulling out the set button (Air Gap) and the module does not power off. It is a real old original design. The 2476D dimmer always had an Air Gap Switch
