Devices that consume power may be individually and uniquely associated with a blockchain wallet into which funds may be transferred. The device can be provided with a client application that executes within the device to determine an energy provider and the cost rate of energy supply. The client application calculates a value of energy consumption by the device and creates a blockchain transaction to transfer a funds value for the energy consumption from the device's blockchain wallet to a wallet of the energy provider. By providing devices that can self-manage their electricity supply and the accounting thereof, billing of power can be decentralized from a meter that meters all supply to a premises to individual devices. The requirement for a central billing entity, billing address, etc. can also be removed.

An energy measurement meter, comprising a first measurement device and a processing device. The first measurement device comprises multiple measurement circuits to receive multiple first sensing signals, and convert the first sensing signals into multiple first sensing data. The processing device is communicatively connected to the first measurement device to receive the first sensing data. The first measurement device is further configured for: setting a first device code corresponding to the first measurement device and multiple channel codes corresponding to the measurement circuits; providing the first device code and the channel codes to the processing device; and providing the first sensing data to the processing device, so that the processing device records at least one part of the multiple first sensing data as multiple first energy data, wherein each first energy data corresponds to the first device code and a corresponding channel code.
