Heiman Zigbee Water Leak Sensor HS1WL-E | 2-Part Leak Sensor with 120cm Cable

Heiman Zigbee Water Leak Sensor HS1WL-E | 2-Part Water Leak Sensor with 120 cm Cable

Effectively protect your home against unforeseen leaks and costly water damage with the Heiman Zigbee Water Leak Sensor (HS1WL-E). This advanced water leak sensor features a smart two-part design: a main housing that you mount dry on the wall and a compact sensor head that is placed directly on the floor via a 120 cm long flexible cable. As soon as the sensitive contact points detect water, your smart home network is immediately alerted.

Smart 2-Part Design with 120 cm Cable

With traditional water leak sensors, there is a risk that the entire electronics will be submerged in the event of a serious leak. The separated design of the Heiman HS1WL-E solves this. The main housing with the electronics and battery hangs safely and dry on the wall, while only the ultra-thin sensor head lies on the floor. The 120 cm long cable gives you maximum freedom to precisely monitor hard-to-reach places behind a dishwasher, washing machine, or under a kitchen cabinet.

3M Adhesive Strip Against Shifting & Anti-Tamper Alarm

Nothing is as annoying as a water leak sensor that shifts due to washing machine vibrations or during cleaning. The sensor head of the Heiman HS1WL-E is equipped with a strong 3M adhesive strip on the underside, ensuring it stays firmly attached to the floor or tile. In addition, the system features an integrated anti-tamper alarm and an automatic low battery notification, so you can always rely on optimally functioning security.

Ecosystems & Compatibility

• Home Assistant: Can be directly and locally connected via Zigbee2MQTT or ZHA with a suitable Zigbee coordinator within Home Assistant.
• Homey Pro: Works excellent with Homey via the official Zigbee integration for starting automatic Flows upon water detection.
• SmartThings: Seamlessly added as a Zigbee water sensor within the Samsung SmartThings ecosystem via a compatible hub.
• Tuya / Smart Life: Fully supported. Connect the sensor directly with a Tuya Zigbee gateway for quick push notifications on your smartphone, historical logs, and automation rules.

Pro-Tip from slimhuisje.nl: Stick the compact sensor head with the included 3M tape directly to the floor behind your dishwasher and mount the main housing with screws at eye level on the wall. This way, you can easily inspect the status LED and battery without having to crawl behind appliances!

Technical specifications

Frequently Asked Questions (FAQ)

1. What is the advantage of the 2-part design with 120 cm cable?

The biggest advantage is that the sensitive main electronics and battery hang dry on the wall, while only the compact sensor head is on the floor. Should a serious flood occur, the main housing will not be damaged and the signal will continue to be sent reliably.

2. Will the water leak sensor not shift if the floor is wet or slippery?

No, the underside of the sensor head is equipped with strong 3M tape. This allows you to firmly mount the sensor head to the floor or tiles, ensuring it stays exactly in place, even with equipment vibrations or during cleaning.

3. Can I directly connect this sensor to Home Assistant or Homey Pro?

Yes, the Heiman HS1WL-E is excellently supported. In Home Assistant, you can connect the sensor directly via Zigbee2MQTT or ZHA using a suitable Zigbee coordinator. On Homey Pro, the sensor works via the standard Zigbee connection.

4. How long does the battery last and how will I be warned when the battery is low?

Thanks to the efficient Zigbee 3.0 protocol, the included batteries last up to 3 years with normal use. When the battery voltage gets low, you will automatically receive a notification via your connected smart home app.

5. Is a Zigbee hub required to use the Heiman HS1WL-E?

Yes, to receive push notifications on your smartphone and set up automations (such as turning off a smart plug in case of a leak), a compatible Zigbee hub or coordinator is required.
