Reallin

What Reallin does

Reallin (Zhejiang Reallin Electron Co., Ltd.) is a Hangzhou, China-based smart-metering and IoT manufacturer founded in 2005, operating through wholly-owned regional entities Smart Meters Technologies (M) Sdn Bhd in Shah Alam, Malaysia and DZG Metering GmbH in Oranienburg, Germany. Its core hardware portfolio spans AMI/grid electronic meters (single and three-phase, AMI smart, multi-function, DTM), EV charging electronic meters (AC Din-Rail and DC), smart water meters (ultrasonic and mechanical), DIN-rail energy meters, data concentrators (C3001, C4011-A) running Linux on ARM with up to 1,000 PLC meter endpoints, LoRaWAN gateways (LW-G100/LW-G200) covering up to 15KM, and the Intellisense BLE 5.0 sensor family (M7004, M7007, M7008). The company holds MID, IEC, EN, CE, SGS and LoRaWAN v1.0.2 certifications across major product lines and advertises an annual production capacity of 7.5 million+ units.

Revenue is generated almost entirely through B2B hardware sales to utilities, energy suppliers, the electrical industry, housing/submetering operators, renewable-energy installers, and e-mobility/charging operators, complemented by OEM/ODM custom manufacturing. Pricing is quote-based and contact-driven via [email protected] and [email protected], with 'bulk low price / in stock' positioning and multi-year enterprise contracts typical of utility procurement. The go-to-market is direct enterprise sales through the multilingual (50+ languages) reallin.com website, augmented by annual European Energy Exhibition participation (2022-2025) and the two regional subsidiaries covering Southeast Asia and Europe. Five primary revenue streams are described: smart electricity meters, EV charging meters, smart water meters, communication modules/IoT devices, and AMI/smart-grid systems. No public APIs, no management team disclosures, and no funding rounds are documented.

Operationally the company is active with current product listings, 2025 trade-show presence, and regional subsidiaries, but financial transparency is low: revenue, headcount, M&A history, leadership roster, and investor backing are all undisclosed, and the listed '1-10 employees' figure is flagged by the source itself as inconsistent with stated capacity and 20-year track record.
