No it’s not in the standard for EU zwave, either, it just wouldn’t be safe. People run all kinds of devices, sirens, pumps, water valves, garage doors, relays – – you definitely don’t want those coming on just because the controller went off-line.
Because the process for doing a network heal on the smartthings hub for the zigbee devices is to unplug the hub and leave it off power for at least 15 minutes, we’d definitely know if this was a common issue, because every time you wanted to repair the zigbee tables, all of your zwave devices would turn on. And that just doesn’t happen.
I’m sure it is happening at your house, but it is not something that is supposed to happen.
Like I said, at this point the only thing I can think of is the power down all your devices and then create a very small Z wave network with one lamp that is not supposed to have anything happen and another lamp which is supposed to come on when a motion sensor is tripped via direct association and just run them for two days and see if they run OK. But I would do it off of the SmartThings network altogether. If you don’t have a minimote, do you have an Aeon USB stick? Basically just set up the simplest possible hardware network. That way if there is just some freak interference in your area like a neighbor with a walkie-talkie, you should see it Happen even with ST out of the picture.
