Product information

Description

The Homematic IP HmIP-WSM digital watering timer in black is designed to automate outdoor garden irrigation efficiently within a residential smart home system. It provides precise control over watering schedules and integrates flow and consumption measurement to monitor water usage. Featuring an IP44 protection rating and a robust weatherproof housing, the device operates reliably outdoors. It runs on AA alkaline batteries with a long battery life and supports convenient operation through app integration, push buttons, or voice commands.

Advantages

This digital watering timer automates daily garden maintenance, eliminating manual watering tasks and reducing water waste by tailoring irrigation to actual plant needs. The integrated flow and consumption measurement functions track water usage precisely, offering clear long-term statistics via the connected app. It includes weather-responsive capabilities that can pause watering during rain or low temperatures when paired with external sensors. The device features a frost protection warning system that sends automatic push messages when temperatures drop. Installation is straightforward and tool-free, utilizing standard thread sizes for quick setup.

Suitable for

  • Automating residential garden and lawn irrigation
  • Monitoring daily, weekly, and monthly water consumption
  • Smart home integration for app-based or voice-controlled watering
  • Weather-dependent garden maintenance with frost and rain adjustments

When it may not be suitable

This watering timer is not designed for industrial or high-pressure commercial agricultural irrigation systems that require continuous heavy-duty operation. It may also not be suitable for locations lacking compatible wireless network connectivity required for smart home system integration.

Key specifications

  • Digital watering timer with integrated flow and consumption measurement
  • IP44 international protection rating for outdoor splash resistance
  • Powered by AA alkaline batteries with a voltage of 1.5 V
  • Battery life of up to 12 months under normal operating conditions
  • Physical dimensions of 137 mm width, 82 mm depth, and 88 mm height
  • Compatible with standard 1-inch and 3/4-inch threaded connections

How to use

Mount the digital watering timer directly onto an outdoor water tap using the manual screw-on connection compatible with 1-inch and 3/4-inch threads. Insert the included AA alkaline batteries to power the unit and connect the device to your existing smart home system according to the manufacturer guidelines. Configure your preferred watering schedules, automation rules, and consumption monitoring settings through the mobile application. Ensure the unit remains protected against severe weather extremes beyond its rating, and monitor battery levels periodically to maintain uninterrupted operation.

What to consider before purchase

  • Verify compatibility with your existing smart home system and app infrastructure
  • Check that your outdoor water tap features a 1-inch or 3/4-inch thread size
  • Ensure wireless signal coverage is sufficient at the outdoor installation location
  • Consider local winter temperatures and remove the device during freezing conditions if necessary

Usage recommendations: Regularly review water consumption statistics in the app to optimize irrigation schedules and conserve resources. Test the automatic frost warning feature before winter months and replace the AA alkaline batteries annually to ensure continuous reliability.

International Protection (IP) code: The IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes".
