So… I got a whole box of UZB3 sticks

Yeah reading a thread on here the other day about different sdk being released and people playing with them. Crazy.

IMO zigbee co-existing with wifi is a dealbreaker for me. Everything wired permanently into my walls is zwave (well except for one Hampton bay fan controller that will be replaced with a second inovelli some day.

I not saying I don’t use zigbee - do have more zigbee devices than zwave. I just feel the wired in stuff is more critical.

There are many manufacturers that do not remove power to the Z-radio via the air gap. They see it as a safety issue only and just cut power to the load path. The Z-radios remain powered. I know those engineers have computers and realize that computers need rebooting now and again. Therefore, I conclude it's a Marketing requirement :smiley:

@jtp10181 Jeff, did the shipper want them back? If not, and if you decide to sell them, Id be interested in taking one or two off your hands (depending on price).

Yes they were very happy to take them back especially since retail value was over $900. Not going to lie, I thought about just keeping them. I guess it was over my unconscious limit, just didn't feel right.

Here is what I got if anyone is interested, the UZB3 is what is recommended for a Zniffer setup and if you just want a cheap USB stick for ghost removal then the 700 chip is cheaper for some reason. Looks like they are out of the 700 right now but the UZB3 would work for either case as well.

I use a UZB3 for my sniffer, and my UZB7 is now relegated to zwave-js/certain z-wave firmware testing (as you can freely change the firmware on the UZBs), so I probably need to pick up another UZB7 anyway. Thanks for the unintentional reminder.

EDIT: As usual digikey is out of stock. But also as usual Mouser has plenty (and they are cheaper, and a Texas company which is a bonus to me):

Curious - Is there a reason to use the UZB3 for a sniffer? Would the UZB7 do the same?

The stick you choose has to be re-flashed and thus is no longer a functioning "ordinary" controller. Yes, it's theoretically possible to flash it back, but you'd have to save the image before you flashed it to a zniffer. Then test it and verify the image was complete enough. I have a saved copy of mine, but I've never really been interested in NOT having a zniffer. No plan to flash it back, in other words.

Thus keeping the "newer" UZB7 for fun and exploration is why I made the exact same choice.. UZB3 for Zniffer, UZB7 attached to PC Controller for ghost removal or anything else I want to experiment with.
