KevinInToronto Posted December 28, 2022 Posted December 28, 2022 I have several 6 button KPL switches and one of them has always had trouble communicating with my ISY994i. It takes many tries to write updates up the device, and it fails with "communication error" often. If I keep trying it eventually works. Can this issue be resolved by replacing components? I recently revived a dead PLM by replacing a few capacitors.
larryllix Posted December 28, 2022 Posted December 28, 2022 Try finding your noise makers that may be interfering with your Insteon signals. Garage door openers were my problem and became very obvious when I installed a second unit containing battery backup. In fact that one crippled all my Insteon signals until I unplugged it. A FilterLinc on each GDO resolved that problem with my KPL.
Techman Posted December 28, 2022 Posted December 28, 2022 @KevinInToronto Have you tried doing a factory reset on the KPL then a restore device. It's also possible that the load that's connected to the KPL is causing issues.

I recently revived a dead PLM by replacing a few capacitors. Curious how old these KPL switches are? You mention switches, not dimmers and my understanding is they stopped making switches a long time ago. I had a KPL switch and it did the same thing and eventually died. I replaced with a new dual band KPL Dimmer and fortunately the load was able to work with dimmer. Maybe changing capacitors will work too. Coinidentally, aartech shows the KPL Dimmer in stock. https://www.aartech.ca/smarthome-insteon
Brian H Posted December 29, 2022 Posted December 29, 2022 If they are the older power line only models. 2486D As pointed out power line communications issues. Can cause communications problems. If you can temporally put the module on a electrical cord and try it in a different location. That may show something. 1
