I can't really answer that from a network standpoint.
But I love that the Ring one will let me detect power outages. With the hub on a UPS and the Ring not on one, I get an event triggered when the Ring switches to and from battery.
Fine Print: This is not a scientific test, I did not utilize any test equipment. So what you are getting here may be purely subjective and opinion based. YMMV
Although most series 2 Ring devices are available in the UK it appears the range extenders aren't (still Gen1). Probably the manufacturing of the plug style, or old stock levels ...
Will pairing the Ring2s as S2 unauthenticated be enough? I'm guessing yes?
So far I've been pairing all the devices to the C7 with no security. Do you know if going from Ring2 extender S2 to no security is okay? I know there was a discussion about a repeater simply repeating frames so it likely wouldn't matter.
Maybe a followup question - instead of no authentication should I actually be pairing the devices as S2 unauthenticated? Given the Rings preference for S2 I'm wondering if other things work better under S2....
I think he was using PIN to mean the Zwave Device Specific Key code used to S2 authenticate the device (which is sometimes obtained by scanning a QR code with your phone)
Yes, during my troubleshooting of that node, I did remove the SmartStart entry. When I had removed it and was ready to reintegrate the switch, I added it back to SmartStart and it worked as intended.
