Notification when my sonoff device cuts from power source

[arslanghouri263]

I need a notification when my Sonoff device loses power. Because I have a lot of power outage in my area so I want know when my sonoff device is not available .

By chance, these notifications do not arrive with a delay of 1 hour or per 1 hour… something is bothering me in the back of my mind.

This varies. You never know. Sometimes notifications come straight away, sometimes after a long time or not at all. I have not been able to observe any patterns. Not good for @arslanghouri263 plans

That’s what I thought… recently there was even a thread about notifications when the device is offline and I think there was a mention of different times. Unless I dreamed it…

I knew I wasn’t crazy.

It usually sends a status report to the gateway every hour. If the gateway misses one of these, you’ll get a warning that the device is offline. But remember, there’s an hour-long gap between these reports.

It depends on the device itself. Like I mentioned in another post. Battery-powered ones tend to have longer periods while main-powered ones are more responsive.

You can alter this setting in some customized zigbee firmware but it would drain the battery quickly if it reports too much.

And that explains everything.

So, to sum up, if someone expects to have fast live monitoring for each device immediately when something goes offline, they should not count on it too much.
