How it works

Setup so simple, your maintenance team will thank you.

"Smart technology" usually means "setup nightmare." Pairing devices to WiFi, managing passwords, and network troubleshooting is a waste of your team’s time.

We built Thea differently. The Thea LD21 is designed to be deployed in seconds. 

Step 1: Activate

  • Unbox the device and pull the battery tab to activate.

Step 2: Place the device

  • Place the sensor flat in the water heater's drain pan or directly on the floor at the base of the tank.
    • No drilling, screws, or adhesive is needed.

Step 3: Assign it to a unit or suite

  • Scan a QR code on the device to quickly tell us what unit or suite it was placed in.

That's it. You're protected.

Behind the scenes

Once placed, the Thea LD21 goes into a low-power monitoring mode. It creates a "heartbeat" check-in periodically to let us know it’s alive and functioning, but otherwise, it stays silent to conserve battery life.

  • No maintenance required.
  • 10 year device lifetime (in standard conditions).
  • 24/7 Connectivity via a persistent low-power cellular connection.

The moment water bridges the metal contacts on the bottom of the sensor:

  1. Instant Detection: The device wakes up immediately and sends an alert to the Thea Cloud.
  2. Notification: We send a text message and/or email to your designated property manager or maintenance lead.
  3. Resolution: Your team visits the unit to fix the minor leak before it becomes a major flood.

Why Cellular?

We chose cellular connectivity to give you absolute peace of mind.

  • Works in Basements: We use a special type of cellular networking (LTE-M & NB-IoT) that penetrates deep within buildings, providing full coverage into mechanical closets, even if they're in basements where WiFi often fails.
  • No WiFi needed: Many buildings do not have property-wide WiFi networks available. Even with an available property-wide network, no connection to your internal corporate network means no cybersecurity vulnerabilities. We are 100% self-contained with no single-points of failure.
  • No hubs needed: Many competing WiFi or LoRa based solutions require range extending hubs, amplifying cost, and complicating setup and maintenance.
  • Future proof: We use the latest low-power cellular chip architecture from a leading semiconductor company to provide service today, and in 10 years.
