Shelly FrankEver smart Wi-Fi water valve, DN20

FrankEver DN20 smart Wi-Fi water valve - with Shelly Control

Take full control of your home water system, irrigation, or pool water with precision. Enjoy automation based on ambient or water temperature and all the advanced features of Shelly smart devices.

With its fine-grained water flow control (0–100%) and support for the DS18B20 temperature sensor (not included), the Shelly compatible FrankEver DN15 Wi-Fi smart valve allows you to build a smart irrigation system that operates on a pre-set schedule or dynamically reacts to changing conditions—like detecting leaks and shutting off the water automatically.

About the Shelly Brand

Shelly is a European smart home manufacturer that offers products using Wi-Fi, Zigbee, and Z-Wave protocols. Its cloud platform provides simple centralized control for its Wi-Fi-based devices, including relays, sensors, roller blind controllers, and energy meters. These Wi-Fi devices connect directly to the Wi-Fi network without requiring a hub, and they can be easily integrated with other systems (e.g., Home Assistant, MQTT). Shelly's Zigbee devices use the standard Zigbee 3.0 protocol, making them compatible with most Zigbee 3.0 gateways.

Shelly’s Wi-Fi-based IoT chips are also available to other manufacturers, allowing an increasing number of third-party vendors to offer smart devices that are fully compatible with Shelly’s Wi-Fi devices and native cloud platform.

Key Features

• Precise Water Flow Control: Adjust the valve position between 0 and 100% for fine-tuned flow regulation.
• Temperature-Based Automations: Configure the device to respond to changes in ambient or water temperature.
• Smart Schedules: Create custom schedules based on your daily routine or sunrise/sunset cycles to optimize irrigation.
• Wi-Fi Operated: Connect directly to your Wi-Fi network—no hub or gateway needed.
• Built-in Battery: In the event of a power outage, the valve can automatically open or close based on your settings.
• USB Powered: Requires a standard 2A USB power supply for operation.
• App and Web Control: The device can be controlled via the Shelly Cloud Control app, Shelly’s cloud-based web platform, or through the device’s own local web interface.
