True Wireless Valve from Uhome offers a completely wireless experience while operating on battery power and reducing installation complexity, cost, and safety concerns. Additionally, True Wireless Valve enables smart monitoring of a manually operated valve. Its seamless integration with Home Assistant and compatibility with the Zigbee protocol overcomes limitations often found in other water management devices, offering you more flexibility and control.

Simple, Convenient, Safe, and Broadly Compatible

True Wireless Convenience: True Wireless Valve demonstrates the power of wireless technology. Being battery-powered, it eliminates the need for additional wiring, offering a true wireless solution that integrates effortlessly into your home environment. This design makes installation easier and eliminates risks associated with high-voltage connections.

Smart Home Integration: Specifically designed with Home Assistant (ZHA) users in mind, True Wireless Valve also supports Zigbee2MQTT integration. It excels at providing real-time feedback and displaying the current status of the valve, whether you operate it manually or through the web interface.

Manual Operation With Monitoring: True Wireless Valve supports manual operation through a conventional handle, similar to standard valves. This allows for immediate, hands-on control when needed. Simultaneously, True Wireless Valve maintains smart functionality by consistently relaying its status back to the hub. This integration with Home Assistant ensures that users receive up-to-date feedback, blending traditional reliability with modern convenience in home automation systems.

Ball-Valve & Clamp Versions Available

The Ball-Valve Version caters to those who favor a more conventional integration with their plumbing systems. This model, which involves replacing your current manual valve, is available in dimensions DN15 (1/2"), DN20 (3/4"), and DN25 (1") with thread options including BSP (British Standard Pipe) and NPT (National Pipe Taper). Installation may require professional assistance to ensure optimal performance and safety.

The Clamp Version is specifically designed for ease of use, as it can be directly attached to your existing plumbing without the need for professional plumbing services or the removal of the existing valve. This setup allows for straightforward installation and immediate integration into smart home systems.

Battery Powered

True Wireless Valve runs on four AAA batteries for up to two years or can be continuously powered by a USB Type-C power supply. Either way, you will not need expensive, complicated home wiring to operate True Wireless Valve.

Smart-Home Integration

True Wireless Valve is designed primarily for residential use and is easy to integrate with Home Assistant (ZHA) and Zigbee2MQTT users. When paired with leak detectors, True Wireless Valve can also enhances home water safety by responding automatically to potential leaks¹. This functionality is a great way to prevent water damage, especially in homes where regular, in-person monitoring might not always be possible.

¹ Requires a hub and leak detectors

Manufacturing Plan

It’s important to note that True Wireless Valve is the first product our team has developed from start to finish. Although this is our inaugural project as a team, each member brings extensive experience in mass production. Currently, we are considering two manufacturing options: producing locally, primarily in-house, or outsourcing under the supervision of our team if the order volume exceeds our capacity to assemble internally. This strategic approach ensures that we can scale operations without compromising on delivery timelines. After assembled, each valve goes through rigorous testing to validate functionality and durability. We will keep you informed through regular updates throughout the manufacturing and testing process.

Fulfillment & Logistics

After our production run is complete, we will package everything up and send it along to Crowd Supply’s fulfillment partner, Mouser Electronics, who will handle distribution to backers worldwide. You can learn more about Crowd Supply’s fulfillment service under Ordering, Paying, and Shipping in their guide.

Risks & Challenges

Certain risks are inevitable when bringing a product to market, and True Wireless Valve is no exception. That said, we’ve taken steps to mitigate these risks where possible. To ensure that we can source all necessary components in a timely manner, we have established relationships with multiple suppliers for core components. This diversification should ensure the timely procurement of all necessary components. Additionally, our team is prepared to implement late-stage adjustments efficiently if required.
