Leak alarms directly on your phone

With LK CubicDetector connected to MyLK, you receive a water alarm directly on your phone if the device detects water (e.g., under the kitchen sink or by the dishwasher). You can also view temperature and humidity where the detector is placed and follow how values have changed over time in clear charts. You can also set temperature alarms to monitor surfaces that risk freezing.

For example, you can place LK CubicDetector in a motorhome and receive early warnings of a risk of freezing in the water tank or leaks in connections. MyLK makes it easy to keep track and act quickly if anything changes.
