How to find 2421 device address with no label?

[blueman2]

I purchased a couple 2421 wireless triggerlincs from eBay used.  Problem is that the address stickers are missing on both units.  Since ISY does not support auto discovery for these devices, I am unable to link them.  I can manually link them to a switch (so I know they work), but how do I link them with ISY without an address?  Is there some way to sniff communications between the 2421 and a linked switch to see what the address is?

Do a Show Device Links Table on the switch. Likely the last active link in the switch will be the link from the TriggerLinc. The Compare button will show the difference and likely will be the TriggerLinc also.

WOW!  Yes, that worked great!  I never knew you could read the link table of a device that was not programmed by ISY.  That is totally cool.  Thanks!

Glad that gave the information. I am worried that the labels were removed.

I am worried that the labels were removed.

 

They were apparently installed using double sticky foam tape.  Most of the tape was removed (some residue left), but all the stickers on the back must have come off with the tape.  At least, that is my guess.  

 

Thanks again!

I did basically the something with a ControLinc that Smarthome took off all the Insteon labels and sold them for a short time as an X10 Controller. The ControLinc is an odd ball.  It can't be linked with the Start Linking Command and holding one of its buttons.

They didn't reflash the firmware. So it and a few other disguised Insteon modules with exchanged labels where a bargain for me.

The big clue was they didn't remove the six digit ID tag from one of them.
