Monsoon Watch

Your first monsoon in a new home, watched.

A leave-behind kit of humidity and leak sensors, with WhatsApp alerts that name the room and a re-scan when the rains are over. Rented by the season, returned after.

Alerts on WhatsApp

Three things trigger a message.

  1. 1A leak sensor detects water.
  2. 2A wall sensor's humidity rises well above its own baseline after rain.
  3. 3The gateway goes offline. Sensors buffer readings and upload on reconnect; a missed check-in raises an alert after a set time.

  • We publish sensor accuracy only from the manufacturer's datasheet and our own tests, once done.

About Monsoon Watch

Ask an inspector

Does it need my Wi-Fi?

No. The gateway has its own 4G SIM and a battery backup, so it keeps working through power cuts. The backup duration is stated once our tests are done.

Will you drill holes?

No. The inspector places the sensors with removable adhesive.

What happens at the end of the season?

We collect the kit, do the post-monsoon re-scan, and refund the deposit after checking the kit, under the rental terms.

Does it measure moisture inside the wall?

No. Wall sensors read humidity and temperature at the surface and alert when a wall's humidity rises well above its own baseline after rain. Leak sensors detect water on the floor.

Possession before June? Book the kit with your inspection.

The inspector places the sensors on the walls that matter most from your report.
