There is a Halo Zigbee device model Halo_RL5601 that mysteriously connects to my hub without me actually doing anything. It’s active for awhile then goes offline and periodically comes back online. If I delete the device, whether in the app/CLI/AWA, it will reappear attached to my hub. Since I don’t actually own any of these devices, I’m thinking it could be a neighbor’s, but didn’t think Zigbee had the signal strength to travel between houses (even though my hub is probably only 40-50 ft from their house). The bigger question to me is how it joins my hub without any interaction on my part.
The distance might be OK, and I suppose there’s a very small possibility that you could have your hub been scanning mode at exactly the same time that your neighbor was trying to add the device to their network, but there’s just no way that should happen more than once. So it sounds more like a platform issue on the SmartThings side. Not an actual Zigbee to hub attachment. ( that kind of thing has been reported from time to time in the forum, like a person whose device list suddenly included a dining room sensor when their house didn’t even have a dining room.)
Definitely report it to support and see what they can see from their side.
By any chance, are you using Mariano’s “Zigbee light multifunction” edge driver? That edge driver does include the fingerprint for that halo model, so I’m wondering if something else that you have is being mislabeled.
Researching further, looks like it’s also in the stock “Zigbee switch” driver.
The stock drivers are part of your hub firmware, they are always going to be reinstalled if you delete them, so that’s not a surprise.
If you want to investigate further, change it to the “zigbee thing MC” edge Driver from Mariano’s channel and let’s see what cluster codes it has. Because those will come from the device itself, not from the edge Driver.
My neighbor did an addition on their house a couple of years ago and that seemed to coincide with when it started appearing which is why I’ve always guessed it could be theirs. The perplexing thing is that it just adds itself to my hub which should not be happening. Guess I’ll have to deal with support to figure it out :-/
