Got a text alert and an in-app SmartThings notification of a leak, but it was detected by a motion sensor? What the heck? I cleared the alert and have not made any changes. Alert shows in Smart Home Monitor history.
Maybe a bug in the latest firmware update?
There have been a couple of “false positives” I’ve observed on my two hubs over the course of a couple of years. Infrequent, but annoying. One was a false ‘motion’ alert that set off SHM. The other, on the other hub, was a false ‘door open’ when it wasn’t. [Edit: the count is now three times.]
That’s what I suspected the first time this was reported, but there have now been three separate reports from different people of motion sensors newly triggering a leak sensor alert from smart home monitor. And only from smart home monitor.
So I now suspect an SHM cloud issue.
In any case, I would suggest that anyone who has this problem report it to support and let them look at it.
