Water Leak Sensors & Humidity Monitors

Quiet awarenessbetween visits.

Water is the most common and most expensive thing that goes wrong in an unoccupied Florida home. Between Avalon's scheduled visits, a few well-placed sensors give your home a voice, so a problem can reach your phone the moment it starts.

Why Sensors

A leak does not wait for the next visit.

Scheduled visits cover a great deal, but a supply line can let go the day after we walk through, and in a warm, closed-up home, humidity from a failed air conditioner can turn into visible microbial growth within about 72 hours. Sensors close that gap. Avalon sets up and places homeowner-owned devices so the home itself can raise its hand between visits, and we can be the ones who answer the alert.

From the founder

This is not hypothetical.

In my own home, these sensors have already gone off four separate times: a toilet supply line, a clogged washing-machine drain, a clogged air-conditioning condensate drain, and the one that mattered most. An overhead unit had a water heater rust through, and it sent water down the shared pipe stack buried in the concrete floor. I was home that day. I heard the alarm, grabbed towels and a bucket, and stayed with it until the tank bled dry, because there is no stopping water on a downhill run, you can only be there to manage it.

Two things stuck with me. In a stacked building you can shut your own water off and still be flooded from above; you cannot turn off the unit over your head. And the only reason I caught it was that I was standing there to hear it. When the home is empty, that alarm rings to no one, and the alert on your phone is what hears it then.

What We Set Up

The devices we set up

A handful of well-placed sensors give your home a voice between visits, with alerts going straight to your phone. You buy and own the gear; we handle the setup and the placement so each one actually does its job.

Leak Detection

Water Leak Detector

Govee Water Leak Detector 1s

From $250

Slim probes placed where water shows up first, under sinks, behind the water heater, at the A/C drain pan, by the washer. The instant they sense water, a 105-decibel alarm sounds at the home and an alert reaches your phone.

  • 105 dB on-site alarm plus phone alert
  • IP67 waterproof, dual sensor probes
  • 5-year battery, reaches across the home
Temperature & Humidity

Wi-Fi Thermo-Hygrometer

Govee H5103

From $150

The early-warning device for Florida. A clean e-ink display that tracks temperature and humidity and alerts your phone when either climbs out of range, the first sign of an air-conditioning failure, long before mold has a chance to take hold.

  • Simple temperature & humidity readout
  • Phone alert when readings climb
  • Joins Wi-Fi on its own, no hub needed
Fridge & Freezer

Refrigerator & Freezer Thermometer

GoveeLife Refrigerator Thermometer Pro

From $150

Probes in your refrigerator and freezer that flag the moment either one drifts, so a power blip or a failing unit does not quietly spoil a full freezer while you are away.

  • Watches the refrigerator and freezer
  • Phone alert if it warms up
  • Confirms the unit is still running

How the pricing works, and how to spend less on the water side

Each price is all-in: the device or devices, plus our setup and placement. The gear is yours; we get it running and watching for you while you are away.

The leak side is where the count flexes, and it comes down to one choice: do you leave the water on while you are away? Shut it off at the main, which we recommend, and the real risk narrows to the air-conditioning condensate line and the water heater, a small, focused set. That is your “From $250.” Leave the water on, and every live source (each sink, toilet, washer, ice maker) is one more place a failure can start, so coverage scales toward the whole home. The humidity and refrigerator units start at one each, and add on only if you want more rooms watched or keep a second refrigerator or standalone freezer.

How It Works With Avalon

You own it. We set it up. We answer it.

01

You own the devices

You buy the sensors from us, and they are yours. We run them and set them up on our app while you are away, then hand them fully over to your own account once you are back in town.

02

We set up & place them

Avalon gets each sensor online, shares the alerts straight to your phone, and places everything where a leak would show first.

03

We can answer the alert

Because the alerts reach us too while they are shared, if a sensor goes off while you are away, Avalon can go to the home and document what is happening, as a separate, scheduled service.

Smart sensors are owned and operated by you. Avalon does not warrant the device hardware, your Wi-Fi network, your phone, or any third-party app that delivers notifications. Avalon is not a licensed alarm system contractor and does not provide 24/7 monitoring or emergency response. Sensor alerts are informational only. Avalon can set up the devices and respond to an alert as a separate, scheduled service.
