HE's biggest weakness :crossout: opportunity

On your own, you could do any of the following very easily when the system boots (note, it is not possible for the hub to know that it is booting after a power outage as opposed to any other reason it might have booted -- which only increases the challenge; unless you think that somehow it should know that it lost power as a distinct case):

• Turn off every switch
• Set the mode based on time of day
• Refresh the state of every device that supports Refresh capability
• Run a list of rules that are intended to restore the state of things
• etc etc

One could leverage the Canary Bulb app written for ST and then run a set of rules exactly as you outlined. This would allow a more automated way to determine how/why the hub rebooted.

Power Failure Recovery via RM?

There is an ST app that uses a ‘canary’ bulb. This works by using a bulb that is always kept off. If the power goes out and then it comes back on, the canary bulb will go to 100% the same as the rest. The app knows if that bulb is on then there has been a loss/restore of power. The app also checks every 5 mins and records the ‘state’ (i.e whether off or on) of each bulb Once it detects a power loss/restore then it will reset the hulbs to the last state. Here is the thread about the app, yo…

I'm sure with the long weekend coming up @bravenel can intergrade this into the next release for full scale power recovery like the OP is requesting. Or they could always do it themselves.

Edit: this actually sounds like a good idea to use the canary bulb app to trigger a rule to refresh the state of all my devices after a power outage.

Edit2: Done. Ported from ST and modified for Hubitat. Uses a canary bulb to detect the power failure and restores a set of switches to their original state. Triggers every 5 minutes or on hub reboot.
