That’s correct
This could theoretically happen with any Zigbee 3 device but we only saw it with a Leedarson bulb that isn’t available in the US or Europe at this time. The best way to exercise this code is by joining Zigbee 3 devices (like our latest generation SmartThing sensors) to a Hub v2 or v3. The issue can manifest even on hubs that don’t support Zigbee 3, like the Hub v2.
Did that 5 times before I posted.
Hmmm, I was lucky then 
Even rebooted my hub. I also noticed that any smartlighting rules with mirroring turn on after a hub reboot now 
And just now, after 1.5 hours… the hue bridge is back online and most of the lights.
Is the ADT water sensor zigbee 3? I think i have a spare one of those in my stash i can test with.
Anyone else seeing hub disconnects every 10 min in Hub Events following the update?
Yes, I am seeing the hub disconnected in the event logs every 10 minutes
Would you be able to submit a bug report in centercode? If not I’ll do one tonight when I get home.
i had a quick one right after the update, but no disconnects since then
Reported it to one of the ST staff who contacted me about my hue lights
And my last unavailable hue light just changed to online
The disconnected messages in the events log have stopped.
It’s not.
For those seeing the disconnect like clockwork every 10 minutes, that is a known issue. Someone smarter can provide more details.
Mine didn’t 
Thanks for the update. Does it require intervention on individual hub? Should I open ticket? Or just wait?
I believe it will require a firmware change but I could be wrong.
The hub firmware team is aware of the issue but it doesn’t look like anyone has filed a bug in Centercode for it.
Love it! If I show mine my wife will finally find out my addiction.
Unless it’s a coincidence with some other measure ST took, rebooting Hue Bridge seems to have stopped the ST hub disconnects.
UPDATE: rebooting Hue bridge only worked temporarily.
