Thank you for the heads up. Just ordered 10 as back stock for failures and new ideas.

Are those the V2 sensors?
Thanks. How long do these last on battery? And what's the motion reset time for them?
I don't use them with a battery.. have modified mine to work with USB. Reset time is like 30-45 seconds or so. If you plan your rules right it won't matter all that much.. just include the extra time as timeout for motion stopped activity.

Mine Iris 3326-L motion sensors last 6-18 months on a battery, depending on how active the area is.
They send an 'inactive' status after 30 seconds of no activity, assuming they are on the current firmware revision.
Note: If you have a SmartThings hub, these can have their firmware upgraded to the latest version by simply pairing them with ST, which will perform an over the air upgrade.

U have 5v running to these without issue?
I wired mine once, but used the 3v from an esp8266 dev board. Didn't realize they could handle straight 5v.
No you need a board.. I've used these:
also have a set of these but have not tried them yet:

Thank you. How can I upgrade their firmware on Hubitat?
You can't... That's why I mentioned using a SmartThings hub (v2 or newer, I believe) as that is the only way possible that I know of, now that Iris has been shut down.

The updated firmware is not a requirement. The sensors will most likely work just fine. However, if you have an issue, at least you now know of one possible solution. Hopefully you have a friend with SmartThings that you could convince to pair your motion sensors, verify/update the firmware version, and then unpair them and return to you. Add a 12-pack and a pizza and you've got a party!

Appreciate you providing the solution. What's the latest firmware version for these sensors?
That's a great idea. I have too many sensors around the house to wire them all. However, I do have a couple that the battery tabs are broken on and I could convert them to USB rather than trying to fix the tabs.

Wait - you updated an outlet?? At any rate maybe a good time to pair all Iris stuff to my old ST before Samsung gets serious about changing things.
Back in that thread, I was using an Iris Hub that I bought specifically to update the firmware on these devices. ST will not update an Iris outlet.

You rat, I just put in an offer and paid for 20 more. 
Cool..thanks.
I didn't see a step down in the pic so I was immediately intrigued.

Has anyone experienced any issues with these 3210-L2 plugs, specifically on the Z-Wave side, specifically with them joining the lifeline? I used @srwhite 's driver and it says “Group 1 not found, configure device!” but configuring does nothing. Would a Zniffer help in visualizing the issue at all?
