TL;DR: An energy meter reader implemented with a microcontroller based logic methodology fused with a building automation system to implement remote load control by home owners using SMS from a GSM phone is presented.
Abstract: Energy conservation and its efficient utilization has been a subject of discourse amongst numerous stakeholders since the industrial age. Advancements in information technology tools thus provides a solution to automating the process of electricity metering as well as remote load control alternatives. This paper thus presents an energy meter reader implemented with a microcontroller based logic methodology fused with a building automation system to implement remote load control by home owners using SMS from a GSM phone. A password based relay circuit was incorporated to ensure secure switching by the user. The system when deployed can enable users query and set energy consumption rates remotely so as to reduce the cost on final consumers as well as conserve energy.

TL;DR: A utility meter as discussed by the authors includes an auxiliary module that couples to the meter housing via electrically safe connections and communicates via ports 2, 5, 6, 7, 8, 9.
Abstract: A utility meter 1, especially an electricity meter, includes an auxiliary module 4, that communicates information from the meter over a network such as a WAN or LAN. The auxiliary module couples to the meter housing via electrically safe connections 3, 6 and communicates via ports 2, 5. The auxiliary module may communicate wirelessly via e.g. GSM or GPRS, or may communicate with a wired network via power line carrier PLC. The auxiliary module may have an additional function such as a card reader, USB port, smoke detector, or carbon monoxide detector. The auxiliary module is interchangeable with other modules. The auxiliary module may also receive data from other utility meters.

TL;DR: This paper formulates the dynamic error testing problem for a smart meter, with consideration and investigation of both the testing signal and theynamic error testing method, and proposes two types of TDLE sequences and three modes of OOK testing dynamic power.
Abstract: This paper formulates the dynamic error testing problem for a smart meter, with consideration and investigation of both the testing signal and the dynamic error testing method. To solve the dynamic error testing problems, the paper establishes an on-off-keying (OOK) testing dynamic current model and an OOK testing dynamic load energy (TDLE) model. Then two types of TDLE sequences and three modes of OOK testing dynamic power are proposed. In addition, a novel algorithm, which helps to solve the problem of dynamic electric energy measurement's traceability, is derived for dynamic errors. Based on the above researches, OOK TDLE sequence generation equipment is developed and a dynamic error testing system is constructed. Using the testing system, five kinds of meters were tested in the three dynamic power modes. The test results show that the dynamic error is closely related to dynamic power mode and the measurement uncertainty is 0.38%.
