About power outages and sonoff relay

Hello, Electricity is frequently cut off here. I set my Sonoff relays to be in the off position when the power comes back on after a power cut. But I want, let’s say there is a power cut, and then came again later. I want it to turn on after 10 minutes when the power comes on. How do I do this?

anyone help?

Hi. I use a stand alone delay off relay that switches on my device after 6 minutes after power comes on after a power outage, just to make sure there aren’t any power dips or spikes just after the switch on. I use a POW R3 to measure my home watt usage, so it switches on after 6 minutes by means of stand alone delay on relay. Does that help?
