Abouto OTOMO

OTOMO is a dedicated provider of comprehensive supporting services for smart meter manufacturers and power enterprise partners, committed to delivering a one-stop, turnkey solution that spans from underlying chip technology to cloud-based communication for the global electricity metering and energy management sector.
With years of in-depth experience in the smart meter industry chain, OTOMO has leveraged its robust technical integration capabilities and supply chain resources to establish a complete business ecosystem. This ecosystem encompasses chip distribution, communication module development, temperature sensing systems, PCB assembly (PCBA) manufacturing, and end-to-end inventory management operations. We act as an authorized agent and distributor for a range of internationally renowned meter-specific chips from leading brands such as STMicroelectronics (ST), Renesas Electronics, Silergy, and ADI. These products feature high-precision metering, ultra-low power consumption, and wide voltage (85–265V) adaptability, ensuring full compatibility with global grid standards.
In terms of communication, we employ cutting-edge Power Line Carrier (PLC) technology to ensure "signal availability wherever there is power," effectively addressing communication challenges in complex building environments. For safety monitoring, we have innovatively integrated fluorescent optical fibers with wireless temperature measurement modules, enabling 24/7 real-time temperature monitoring of critical electrical nodes and truly preventing potential hazards before they arise.
Furthermore, OTOMO is equipped with professional automated PCB assembly production lines that adhere strictly to industrial-grade process standards. This enables us to swiftly respond to customized customer requirements and significantly shorten product time-to-market. To address the prevalent inventory pressures in the industry, we also offer meter terminal inventory consignment services. By precisely matching downstream channel resources, we efficiently revitalize stagnant assets, helping our partners achieve secondary value appreciation of their resources.
Guided by our mission to "ensure that every unit of electricity is safe, intelligent, and controllable," we continuously drive the localization, intelligence, and green development of smart meter technology. We are eager to collaborate with global clients to co-build a more efficient and reliable future for smart energy.
