As an experienced OEM/ODM manufacturer of smart home electrical products, XINGLIAO (Shenzhen Xingliao Intelligent Technology) presents the DS-121GWN smart water heater switch with built-in energy metering. This model is engineered for overseas B2B buyers who need a reliable, measurable and cost-effective way to control electric water heaters while tracking real power consumption.
Therefore, The DS-121GWN adopts a clean 86mm wall-plate form factor with a premium matte finish, available in multiple colors to match different interior styles. Its most distinctive feature is the integrated energy metering module, which measures voltage, current, active power and cumulative energy in real time. Buyers can read these figures directly on the switch display or through the companion app, giving end users a transparent view of how much electricity their water heater consumes every day. This is particularly valuable in regions with high electricity tariffs, where energy visibility directly translates into lower bills.
Moreover, From an engineering perspective, the switch supports both single-fire and neutral-wire installations where applicable, and it is compatible with common water heater loads up to the rated capacity. The internal relay is rated for high inrush current, ensuring stable switching of resistive heating elements over a long service life. Overload and over-temperature protection are built into the firmware, and the device automatically recovers after a fault is cleared, reducing after-sales service pressure for importers and distributors.
In addition, For smart home integration, the DS-121GWN connects over 2.4GHz Wi-Fi and works with major platforms, allowing remote on/off control, scheduling, countdown timer and energy statistics. Voice control via mainstream assistants is also supported in many regions, which simplifies daily operation for end customers. The configuration process is straightforward and localized, an important factor when rolling out products across different countries.
For example, As a factory with strong R&D and production capabilities, XINGLIAO offers flexible customization for the DS-121GWN. We can adjust the printed logo, packaging, UI texts, app branding and even functional parameters according to your market requirements. Our certifications cover CE, FCC, RoHS and related standards, and we provide complete technical documentation, test reports and after-sales support for our partners. MOQ is flexible for trial orders, and mass production lead time is well controlled to protect your inventory plan.
