gbbell Posted September 9, 2021 Posted September 9, 2021 I’m having an Insteon signal reliability problem that is inconsistent with my understanding of how dual band devices repeat signals. I was hoping someone could offer some insight. I have about 20 Insteon devices in my home but the relevant ones are: • ISY/PLM upstairs • ToggleLinc switch in the garage, load connected to overhead garage lights • KeypadLinc inside near garage door, button A set as a controller and responder to the garage light connected to the ToggleLinc ISY programs turn on/off the garage light (ToggleLinc) according to several conditions (timer, garage door open/closed, etc.). About half of the time this works fine, but the other half it does not, suggesting that the command from the ISY does not reach the ToggleLinc. However, button A on the KeypadLinc (responder of the garage lights) is always updated by ISY commands, suggesting that there is no problem with ISY commands reaching the KeypadLinc. Furthermore, when I press button A on the KeypadLinc (controller for the garage lights), the lights always turn on/off, suggesting no issues with KeypadLinc commands reaching the ToggleLinc. My question is: If ISY commands reliably reach the KeypadLinc (because the button LED status is always updated) and commands from the KeypadLinc reliably reach the ToggleLinc (because physically pressing the button reliably turns on/off the lights), then why doesn’t the dual-band KeypadLinc successfully repeat the ISY commands it receives to the ToggleLinc? Hope that makes sense. It’s been bugging me for a few years. Thanks.
Techman Posted September 9, 2021 Posted September 9, 2021 Take a look at the following article. You also need to make sure that both legs of your powerline are bridged using dual band devices. The attached ISY Cookbook is also a valuable source of information. INSTEON: Troubleshooting Communications Errors - Universal Devices, Inc. Wiki (universal-devices.com) ISY Cookbook.pdf
Brian H Posted September 9, 2021 Posted September 9, 2021 (edited) The ToggleLinc is a power line only module. Depending on the model of the KeypadLinc. It could be a power line only one also or the newer Dual Band model. It is possible you have a power line signal issue. The above articles may help you in your communications checking.

Brian H Posted September 9, 2021 Posted September 9, 2021 (edited) The Insteon Details paper also gives information on how it works. It seems to be hard to find lately. Though I did find an archive to it. https://github.com/pyinsteon/pyinsteon/blob/2533494a8b13b30b2d0938c9a18afe782b740410/docs/dev_guides/insteon_details.pdf Edited September 9, 2021 by Brian H 1
