So here’s my setup: I have a smartthings hub, a couple Dome door sensors (require device handler which I would assume would be cloud, but they show up as Local devices) and an ecolink door sensor which shows up as local and required no device handler. These are the inputs and the output is the dome siren. My hub is connected to my wifi router, and the router to the internet via LAN cable to my modem.
The scenario is that someone could easily cut the phone/cable line and break in. (It’s a common tactic for thieves). My Ecolink sensor (local) should still be able to trigger the base “z-wave siren” device type that my Dome is set up as, which is also local. I’d lose the functionality of the chimes and bells of the dome using this method (like Kwadyote mentions above) but at least I should get the siren still working.
Problem is, with my LAN cable connected to the modem, All work perfectly well, I even get push notifications on all mobile devices. When I unplug the LAN cable connecting the router to the modem, nothing happens when the sensors are tripped. When I finally plug the cable back in, then i get the push notifications on mobile devices about all triggered events.
I would assume since the ecolink door sensor AND dome siren are both running local and the device handlers are also local, shouldn’t the door sensor trip the siren? Am I eating crazy pills?
