The invention discloses a meter reading method and device, an electric meter and a storage medium. The method comprises the following steps: selecting a plurality of sub-time periods distributed for an area where the current electric meter is located in a total time period; querying the electricity utilization data recorded in the total time period in the current electricity meter; according to the power consumption data, respectively marking a user power consumption level for each sub-time period; sending the sub-time period and the user power utilization level to a server, and receiving a target time period sent by the server; if the target time period is reached and the current electric meter does not meet the relay condition, detecting beacon frames broadcasted when other electric meters meeting the relay condition serve as wireless access points; selecting a plurality of other electric meters meeting relay conditions as relay nodes according to the beacon frames; accessing a relay ...
