Smart Home Greywater Sensors Market Report 2026

The smart home greywater sensors market size has grown rapidly in recent years. It will grow from $0.97 billion in 2025 to $1.12 billion in 2026 at a compound annual growth rate (CAGR) of 15.5%. The growth in the historic period can be attributed to increasing residential water consumption, early adoption of water-saving fixtures, rising awareness of water reuse practices, expansion of smart home adoption, availability of basic water quality sensors.

The smart home greywater sensors market size is expected to see rapid growth in the next few years. It will grow to $2 billion in 2030 at a compound annual growth rate (CAGR) of 15.6%. The growth in the forecast period can be attributed to increasing water scarcity concerns, rising investments in sustainable housing, expansion of smart city water management, growing demand for automated water reuse monitoring, increasing regulatory support for water conservation technologies. Major trends in the forecast period include increasing adoption of residential water reuse systems, rising deployment of wireless greywater sensors, growing integration with smart home platforms, expansion of real-time water quality monitoring, enhanced focus on household water conservation.

The rising interest in smart home solutions is expected to drive the growth of the smart home greywater sensor market. Smart home solutions consist of interconnected devices and systems that allow residents to monitor, control, and automate household functions such as lighting, security, climate control, and water usage via digital platforms. The growth of smart home solutions is driven by consumer demand for automation, which enhances convenience and optimizes resource management. Smart home greywater sensors support these systems by monitoring and managing wastewater reuse, improving water efficiency while integrating with home automation networks. For example, in February 2025, Ubisense, a UK-based software company, reported that connected Internet of Things (IoT) devices reached 16.6 billion in 2023, a 15% increase from 2022.

Major companies operating in the smart home greywater sensors market are concentrating on developing advanced real-time water usage monitoring technologies to improve household sustainability and operational efficiency. Real-time water monitoring refers to a digital sensing system that continuously tracks and reports water flow and usage patterns, enabling consumers to better manage and conserve water. For example, in January 2025, LIXIL Corporation, a Japan-based technology company, launched its smart home water sensor, Droplet, at CES 2025, emphasizing accelerated water conservation efforts for homeowners. Droplet features best-in-class accuracy and an intuitive design, installs within five minutes without tools or a plumber, and measures water flow up to 50 times per second, providing detailed insights into consumption behavior and enabling advanced leak detection. The solution equips users with actionable data to enhance efficiency, reduce water waste, and lower utility costs while supporting sustainable living practices. LIXIL’s debut of Droplet at a leading technology event highlights the industry’s shift toward accessible smart sensors that help make environmental impact more tangible for consumers.

In May 2025, Belkin International Inc., a US-based consumer electronics company, acquired Phyn LLC for $24.9 million. This acquisition provides Phyn with strategic support to expand its market presence and accelerate adoption of smart water management solutions. Phyn LLC, a US-based company, specializes in intelligent water systems focused on leak detection and water monitoring using ultrasonic sensors and advanced artificial intelligence (AI).
