I have had to replace a dead PLM and subsequently all my programs that listened to fast on or fast off are no longer working.  I have recreated programs, recreated the affected scenes, deleted and re-added devices, restarted ISY-994i and re-restored PLM to ensure catching the new address...  no luck

 

I do have timer based programs that still work.

 

The new plm also seems to lose contact with devices more often than the old one.  no other changes in the house.

 

any ideas?  I do not have a valid backup, so if I have to start over it will be a long process for about 60 devices.

 

thanks!

Was the Wiki process described in Wiki section 6.1 used to replace PLM?

I did make the mistake of plugging in the new one while ISY was on, but I followed the recovery instructions in the how-to on this forum and power cycled the ISY and re-restored PLM.  probably three or four times by now.

Pick a device that is not sending commands to the PLM (not triggering a Program) and run Tools | Diagnostics | Show Device Links Table.

 

Do the link record(s) have the old or new PLM address?

The first (0) record is the new PLM.

If that link record starts with an E2 and is pointing to the new PLM the commands from the device should reach the PLM unless there is a comm problem.

^{the full entry reads 0 : 0FF8 : A2 00 2B.96.C# FF 1F 01}

That is a Responder link.   Look for a link that starts with E2 and has the new PLM address.   The E2 is a Controller record pointing to the new PLM which is required for the PLM to receive commands from this device. 

Now you are on to something. That link does not exist.  I traced the four E2 entries to other devices with scenes in common with this switchlink.

The device will not send messages to the PLM without that link.  Is it possible a Delete Modem (PLM) was done?

It was not deleted, just replaced and restored.  Do I have to delete all devices and re-add them?

I would first try a Restore Device.   If the ISY thinks the E2 link should exist it will rebuild the link database with that link.  If the link does not come back the ISY has lost the information about the PLM and deleting/readding the device is the way to rebuild the device link back to the PLM. 

I have tried restores on several devices.  The E2 link you are looking for is not in the ISY link table, so it is not restored. 

 

What is the most painless way to remove and re-add 60 devices and still get the new PLM link added?  Will I have to trash all my scenes and recreate those as well?

Deleting and adding the device will resolve the missing E2 link record.  I would display the device link database after the add to double check the E2 link record pointing to the PLM was created.  The devices are removed from the Scenes during the Delete.  The Scenes will have to be rebuilt for the deleted devices.

 

There is no fast means of processing a large list of devices. 

oy, it seems I also have new communications issues.  The new plm fails to connect to some of the devices to run diagnostics, even ones with dual band comms.

Hi ScottAvery,

 

I strongly recommend moving your PLM to a different outlet and retry.

 

With kind regards,
