A practical, step-by-step guide to placing Wyze Sense Leak Sensor & Probe for the best early warning. Learn the best spots for leak detector coverage and how to avoid common setup mistakes.

Quick answer

Place the Wyze Sense Leak Sensor flat on the floor or cabinet base where water will pool first, and run the probe into the lowest point of the risk zone. Prioritize under-sink cabinets, water heaters, washing machines, and basement corners. Keep the sensor and probe within range of your Wyze Sense v2 or Wyze Home Monitoring hub.

What to check before you place anything

Before mounting or dropping sensors, confirm your hub is online and the Wyze app shows the sensor as connected. The Wyze Sense Leak Sensor & Probe requires Wyze Sense v2 or Wyze Home Monitoring to operate, so a missing or offline hub is the most common reason a placement test fails.

Walk each risk zone with a flashlight and look for the lowest point. Water follows gravity, so the sensor should sit where liquid will actually collect, not on a high shelf or behind a pipe where it stays dry.

Map your highest-risk water zones

Not every room needs a sensor. Focus on locations with a constant water supply or a history of moisture. Under-sink cabinets, water heaters, washing machine hoses, dishwashers, refrigerators with ice makers, and basement floor drains are the usual suspects.

If you have a multi-floor home, place at least one sensor on each level. A slow leak on an upper floor can travel along joists and show up far from the source, so early detection near the appliance is more useful than a single sensor in the basement.

Position the sensor and probe correctly

The sensor body should rest flat on the floor or cabinet base with the contact points facing down. The probe is designed to extend into tight or low spots where the main unit will not fit, such as behind a toilet or under a dishwasher.

Do not suspend the sensor or probe in the air. Both need direct contact with water to trigger an alert. If the probe cable is too long for the space, coil the excess loosely and keep it out of the way of moving parts.

Step-by-step placement

Step 1: Pick the lowest point in the risk zone: Shine a flashlight along the floor or cabinet base and find where water would pool first. That is where the sensor or probe belongs. Checkpoint: if the spot stays dry during a spill test, move it lower.
Step 2: Place the sensor flat, not upright: Set the Wyze Sense Leak Sensor flat on the floor with the contact points facing down. Do not stand it on its side or stick it to a wall. Common mistake: mounting the sensor vertically so water runs past it without touching the contacts.
Step 3: Run the probe into tight spots: Use the probe for areas where the main sensor will not fit, such as behind a toilet base or under a dishwasher. Keep the probe tip in the lowest point. Checkpoint: gently tug the cable to confirm the probe stays in place.
Step 4: Test with a few drops of water: Drip a small amount of water on the sensor contacts or probe tip and confirm the Wyze app sends a notification. Dry the sensor completely afterward. If no alert appears, check hub connection and battery before repositioning.
Step 5: Label and document each sensor: In the Wyze app, rename each sensor by location, such as Under Sink or Water Heater. Note the placement date so you can revisit it if you rearrange cabinets or appliances. Next step: set a yearly reminder to re-test each sensor.
