Scene Link Creation Troubleshooting

[matapan]

Can anyone recommend the best way to troubleshoot link creation when one creates a scene?

I have many scenes where there are multiple devices which act as as controllers for one device which acts as a responder. Once I have created the scene, I noticed that some of the controlling devices don't reflect the state of the scene.

For example, if I have a Switchlinc dimmer which acts as a controller and responder in a scene, with a button on two Keypadlincs which act as controllers, I expect that when the Keypadlinc button is turned on, the button on the other Keypadlinc acting as a controller is also turned on, as well as the Switchlinc dimmer. With recently created scenes, I noticed that the state of the button or paddle which is not pressed is not updated with the current scene state. Older scenes I have created are correctly updated.

Any thoughts on the best way to troubleshoot this? Thanks!

You can start wirh scene diagnostics, right click on the scene then click on Diagnostics | Scene test

Post a screenshot of the results

Either you have a communication issue between the devices and your PLM, i.e. noise on the powerline, or the link tables in your devices are corrupted.

First thing to try is right clicking on each of those devices and then click on restore device. That will rewrite the link tables that are stored in your controller to the devices. After the device restore run the scene test again to see if the issue has been corrected.

How reliable is the scene test feature? I tested a scene twice and received back two completely different results. One where all devices in the scene failed, and one where all devices in the same scene succeeded.

I did find that installing more Filterlincs for some other circuits helped rectify communication issues. How can one tell between a failing PLM with communication problems caused by a noisy line? Thanks!

The scene test is very reliable. It appears that your problem is/was caused by noise on the powerline.  How old is your PLM, the date code is the 4 digets on the plm sticker. Based on what you've described, It doesn't appear to be a PLM problem. If the PLM was failing it would effect more than just your scenes.

A UPS or other electronic devices can wreak havoc with the Insteon powerline signals. A good start is the Fillterlinc.

Take a look at these two articles:

To @Techman's point: flaky, inconsistent behavior is one of the symptoms of a dying plm

The scene data resides in the devices of the scene, as well as the controller and PLM

You could turn off the controller, unplug the plm and the scene will still work, assuming there's no powerline issues. i.e. if you disconnect the controlller and plm and then manually turn on one of the switches in the scene, the rest of the devices in the scene will respond accordingly.
