I'm not sure adding a repeater with security really makes any difference - if anything it seems like this is a device that really doesn't need security. As I understand it, the repeater will repeat both secure and unsecure packets... so not sure what you gain. As long as the repeater is paired successfully, that is. If the lack of security is a result of a failed pairing that's another issue.
It’s normal (and expected) for a Z-Wave device to be assigned a new device ID after being excluded and then included.
As for the other issue (inclusion without S2), that determination is made at inclusion time. At least two possibilities: (1) it was a faulty inclusion - go through the exclusion/reset/inclusion again, or (2) are the two RE7 devices on the same firmware update level?
I’ve got two of them and have never seen this. Both of mine are paired S2.
Do you have a ghost left over from the initial pairing/removal? That would cause problems trying to bring it back in.
After making sure no ghosts are present (that is key!), do a pre-emptive exclusion on the RE7 before trying to re-include it.
When you re-include, the first prompt you get should be a "Do you want to include with or without security" prompt. IMHO, there's really no good reason to pair these as S2, but if you want to, that's when you'd next enter the 5-digit DSK. If you elect to include with no security, then it will end up showing as "None" (not "S0") for security in the ZW details page.
FWIW, I have all 4 of mine paired as "None" security.
no longer accurate.. i have mine without security and it works fine for those funcionts
I'm not sure what you are referring to as "no longer accurate."
Security does not cover or affect repeating functionality of any device. Security does cover commands sent to the RE7 itself, such as power level and range tests. These are intrinsic behaviors of Z-Wave and have not changed.
I don't believe that @672southmain was implying that the RE7 power level and range test features did not function unless security was enabled. There are some devices that do implement restrictions if not paired securely (garage door openers come to mind), but the RE7 is not one of them.
If the RE7 is paired without S2, it is of course open to a minor denial of service attack. But I view this as a very minimal concern, and have my RE7s paired without security.
But, if an RE7 is paired insecurely, I believe it might be possible to inject power level commands into the mesh to the RE7 and cause it to do repeating diagnostic tests. But, it would also seem possible to jam a Z-Wave mesh with ignored traffic even if everything on the mesh was paired S2, thereby causing DoS.
Thanks...and both of these repeaters that I have are intended to help with lock/door type devices that I believe will benefit from the S2. Hence, my original reason for posting here that for some reason I can't seem to get the repeater to pair with security option.
Tempted to reset the radio entirely at this point and start over.
