Device Behavior After Power Outage?

It’s clear enough that Vera herself recovers just fine from power outages, and goes about her business once power is restored. But… I got to wondering about how Z-Wave devices would fare under such conditions?

Some questions concerning the behavior of paired devices:

  1. When power returns after an outage, and Vera wakes back up, does Vera make any attempt to restore devices to their state (“On”, “Dim 50%”, etc.) prior to the outage?

  2. Could controls be added in Vera’s UI, say on the ‘Devices’ page, to govern whether Vera will or won’t try to restore a device’s prior state, following an outage? Or a third option, such as “Leave ‘Off’ following power outage”?

My rationale behind these questions is:

  1. When power to my home is lost, I currently walk from room to room making sure that all light switches are OFF, the thermostat is turned OFF, and so forth … lest these devices experience the brown-out-like voltages and spikes associated with the sudden return of power.

  2. More importantly, I’ve always believed that multiple outages in succession (not uncommon in my part of the country) are precipitated by customers leaving so many electrical appliances ON … so that when power is restored, the immense load on the lines is apt to cause a 2nd, 3rd black-out.

I believe Vera - who already is able to respond to utility companies’ “Flex Alerts” during peak usage - could be put to even better use during blackout/outage scenarios.

Any ideas, folks?

Vera does not save current state of devices and of course when power goes out, it wouldn’t be able to do so, unless it is connected to UPS. So, when power gets restored, Vera boots up normally and does not try to restore any previous states.

As of devices - some of them allow setting initial state, but most just default to Off state, when power is applied/restored. So, unlike with the regular light switches, you don’t have to turn all the lights off manually during blackout. Not sure about the thermostat though, as I don’t yet have a Z-Wave one…
