First time poster, forgive me if I’ve picked the wrong thread category, etc. I’ve been living happy with my Smartthings home for about 2 years now and everything has been going great!
Until recently. I don’t exactly know when because I’m not usually up at 1am, but it seems to have coincided with a recent app update when my hub started having issues connecting to the cloud (now resolved with some reboots). I think it’s just been the last few weeks otherwise I would have noticed a disconnected Ring camera.
I’ll get to it: every day at 1am every zwave device I have that’s on, turns off. Not exactly 1am; when I go into the IDE it’s 1am and 29 seconds or 40 seconds or 31 seconds depending on the device.
I can’t find a single link between devices except zwave. I mostly use Zooz Zen27 switches, but I also have two zwave smart outlets (different brand I can’t remember) that are doing the same thing. Every zwave device that’s on, it seems, turns off at 1am. No other types of devices are affected (wifi Kasa plugs, other wifi plugs, linked Logitech Harmony devices, etc.). Some devices are part of “smartlighting” automations (turn on/off at sunset/sunrise respectively) but others should be on 24/7 and have never been part of any automations (security camera for instance). No notable events in the hub log (disconnections, etc.), and the device events just say they were turned off. Looks like my hub is hardware V3.
I’m just at a loss of what to do. This is a relatively serious security issue; all my outside lights, a Ring security camera, landscape lighting, and all inside lights turn off in the middle of the night when they most need to be on! I have made no new automations and added no new devices for quite some time. I use Alexa integration, but there’s nothing in the Alexa history about turning off these devices. The IDE history can’t seem to tell me anything about what triggered the events and while all are between 01:00 and 01:01 the random seconds involved has me a little puzzled. I have round about 27 devices in total and so burning everything to the ground and factory resetting is really not an ideal option.
Can anyone suggest some troubleshooting steps, or any way to track down what’s triggering these events? I’m headed out of town next month; this just can’t happen when I’m gone. It’s just crazy to me I’ve made no changes in smartthings, I haven’t even opened the app until recently, and after 2 years suddenly everything is going haywire! Thanks!
