Why a device does not return to the last state after a power outage but remains off?
This may be caused by your inching settings for the device. When inching is enabled on a device, the power on state settings will not work. According to the firmware, when a device is in inching mode, its final status will be off. Therefore, they will override the settings of power on state and remains off directly.

The same issue on my device. Is it going to be fixed?

Hi,
Sorry for the inconvenience.
It is determined by our tech team that power-on state should work this way.
Please note that it is not an issue but an intentional firmware feature that the power of the
device will remain off if inching is enabled regardless of the power-on state.
Your kind understanding would be much appreciated.
If that is not an issue than it is an important limitation and it should be mentioned in application, otherwise it is a bug.

Please note that this is a feature of the firmware, not the application, so it isn't specified in the application.
Pls note that your many customers need Power State ON feature in inching mode eagerly. It is giving hurdle the way we want to use the inching feature. If there is a option to select then why it ignore it on and react as off every time the power came. It become a useless switch if it not work this way.

I understand this feature is important. However, this is a firmware feature that makes it act like that. We can only update the software. We will reach out to our partner device makers about the request concerning this firmware feature. However, it is up to them whether or not to take it. Many thanks for your kind understanding.
I have the same problem and I AM not using Inching and my inching is off position. Then also if power goes off and when back Network and power LED Glow on position except switch. I have to Manually switch off and switch on then it work.

We plan to make improvements on this feature.
Could you name some user scenarios when you need inching to turn on and off devices when
power-on state is set as on?
Hello sir
I had a problem with the excellent sonoff s20 sockets which is that the socket remains off when the power returns after a power cut.
I read your answer which is that it is due to the firmware of the socket so there was not much that could be done.
My programming is that my refrigerator remains off from 00h00 to 04h00 if there is a cut in this time slot that does not cause any problems. And in the time period from 04:01 to 23:59 the refrigerator must remain on, but if there is a power failure, the refrigerator will remain off according to the firmware of the socket.
My proposition:
If in the loop cycle, in the loop type, according to a delay of your choice, we could define the time range to select an on or off state, I think this to solve the problem.
If the return of the current is cut in the range 00h00 to 04h00, the socket remains off and as programmed to be switched off, no worries.
But if in the time period from 04:01 to 23:59, the outlet must be on but if there is an interruption and return of power, the outlet will remain off but with the time defined in the loop, the outlet will take the state on during any this time slot.
Here is my solution so I am waiting for the update for the loop cycle

I use a SONOFF BasicR3 for a fan in bathroom connected to a switch as well. Inching is set to switch off fan after 30min. If wall switch is flicked when someone enters bathroom after inching turned it off, the fan will not switch on as the unit is set to POWER STATE OFF. I have to use ALEXA to turn the unit on again....
This is not practical when using inching. It should reset device to last power state. A wall switch should be able to turn it on again.
Hi,
Can you add to the conditions, in addition to "on" "off", "online" "offline" so this issue made intentionally by firmware will be solved by application.
Thank you!!
Here's how I got around this. Leave power on state to ON. Leave inching OFF. In the Sonoff app, create a manual scene to turn off the Sonoff. Then create an auto scene that is triggered by the unit powering on that delays for the desired time and then calls the scene to turn off the unit.
So if the power (eg wall switch) comes on, the connected device turns on, triggers the scene which delays and turns off after desired time. The wall switch will always have control but no one can leave the connected device on for too long.
@Greg Altena: This works for me! Thank you very much.
@Greg Altena You are KING
Many of us need inching mood and the power on state mood at the same time. Or else the switch is useless to me. And i think others will agree with me
Have done many auto scenes in the past but not a manual one. Not sure what the “If this” can be but the action is the delay followed by the OFF . So the trigger for the auto scene is the power up of the sonoff from the wall switch and needs to action a manual scene. I get the idea but I’m not quite sure of how it is implemented with the two scenes. “ I need more clues, Watson! ……. Regards, Sherlock”.
Later....... I did work out how to implement it, but using the delay in the Manual scene.
Now I want to test if it still works when the unit is OFFline and also if wifi gets switched off will the scene still operate. …. Cheers!
UPDATE… I found that the de-powered sonoff was off-line.
I switched it ON from a latching mains switch.
It turned ON the load straight away within 1 second.
In my Manual scene, I had a TEST count-down of 10 seconds.
It was obvious from observation, that the countdown didn’t start until the wifi was connected.
(As indicated by the green LED light flashing then going solid.)
Having put the timeout (inching time) in the manual scene that performs the OFF function, maybe the time-out should have been in the auto scene and then, just trigger a manual OFF. More experimenting needed. Regards, Sherlock.
