When there is a power failure, you should press the white button on the electricity meter.

If there is a sudden power failure, you can press the white button on the meter for five seconds to restore power supply. Now there are two kinds of instruments, one is intelligent instrument and the other is plug-in instrument.

If it is a plug-in meter, you should take the electric card to the property or electric power business hall to recharge the payment after the power failure. After the recharge is successful, plug it into the card slot of the electric meter, and when you hear it, there will be electricity. If there is no electricity when plugged in, first check whether it is plugged in successfully. After confirming that the insertion is successful, re-insert it later to see if there is electricity. If the smart meter is dead, we can pay according to the number of users on the mobile phone. After it pays, there will be electricity at home in about 5~ 10 minutes.
