I recently experienced a power outage. I noticed if my Linkind zigbee repeater device's plug was On, it does not restore to On when power is restored. However, it does create an Off (physical) event when power is removed.
A Sylvania Repeater/Plug acts similarly. A Samsung Repeater/Plug does return to On, if it was On when power is removed then restored (at least in my short duration tests)
Does anyone know how these devices should work after a power outage, or is it up to the manufacturer?
Using RM my workaround for the Linkind plug that must be on
Turn the device plug on when power is restored. (Hub is on a UPS)
It's up to the device manuf. and drivers to make use of those capabilities. There are similar issues w/bulbs, some can be set to return to a specific state, others cannot. Even w/in the same brand you may have differences in behaviors in this area.
I’m pretty certain the Hue plugs retain their previous state when power is restored, it’s selectable on the Hue bridge, but I can double check their behavior on Hubitat.
The Generic Zigbee Outlet driver does not offer preference "Power restore state" available with some bulb drivers or perhaps some device specific plug/outlet drivers.
There is a physical On/Off button on most plugs. When power fails and the plug is powered On, many plugs/outlets manage to report a physical Power Off as if the On/Off button was pressed, making the "Power restore state" preference unusable without also knowing if the last Power Off was actually a power failure, not a button press.
Just for reference, my Sengled Zigbee plugs (ETL certified and act as repeaters) maintain their power ON/OFF state when power is restored (so it must of course be due to the device manufacturer and drivers). Just tested by unplugging and plugging into outlet as a test for you.
Yup - and Sengled bulbs have different behaviors depending on type - their color bulbs don't maintain their power state, while the plain white bulbs evidently do (from a post in another recent thread on this issue).
