I don't know if it reconnects after replugging the power. I have not been near the device for 4 months now. It could also be that the router restarted and...

No, disconnecting from power and reconnecting did not help. Full Wifi reset was needed to reconnect it back to the network.

But how EWPE Smart installed on my phone is able to configure it?
