Eddy vs LAIIER: Detection that can shut off the water, not only alert you.
Both detect leaks with wireless sensors on LoRaWAN. LAIIER's Severn WLD alerts your team by email and SMS. Eddy can also shut off the water, closing a valve by rule or on an operator's command.

Where Eddy and LAIIER differ
| Feature | Eddy | LAIIER | Why it matters |
|---|---|---|---|
| Automatic shutoff | Eddy IQ and Eddy Link valves, by rule or operator | None stated, Severn WLD is a leak sensor | Closing a valve is what stops the damage. An alert alone only reports it. |
| When a sensor fires | A trained operator calls your team, 24/7 | Email or SMS alerts to your facilities team | An alert at 2 AM only helps if someone acts on it. An operator on the phone gets your team moving within minutes. |
| Flow monitoring | Eddy IQ meters and inline flow meters | None stated on its website | Flow catches water that never reaches a sensor, like a leak inside a wall or a fixture left running. |
| Record of each event | A Leak Incident Report for every confirmed event | Leak data and analytics in LAIIER Cloud | At renewal, insurers ask what happened, how fast it was caught and what was done. A report for every event answers all three. |
| Sensor battery life | Primary lithium, 7 to 10 years | 6 years on one AA lithium cell | Battery swaps mean entering units and opening ceilings. Across hundreds of sensors, a longer life means far fewer visits. |
| What both have | |||
| Leak sensors | Eddy H2O sensors for water, humidity and temperature | Severn WLD printed tape with 12 detection zones | Sensors where leaks start, at fixtures, fan coils and risers, find water before it spreads. |
| Network | Eddy's own LoRaWAN network on cellular or Ethernet gateways, no building Wi-Fi | LoRaWAN, gateways supplied or on your own network | The network decides what the system can see. Leaks start in mechanical rooms, risers and concrete cores, where Wi-Fi and cellular signals often fade. |
| Construction | One system from fit-out into occupancy | Construction monitoring on a standalone LoRaWAN network | Job sites sit empty after hours with water lines charged. A system that carries on into occupancy protects the building without a second install. |
| Customer support | A project manager, then a Building Success Manager | A dedicated Customer Success Manager | Someone has to place the sensors, set the alert rules, test the valves and keep the call list current long after go-live. |

Detecting the leak is half the job. Stopping the water and closing the incident is the rest.
Detect and shut off
LAIIER's Severn WLD is a leak sensor, with no shutoff stated. Eddy IQ and Eddy Link valves run on the same network as the sensors and close a line automatically or on an operator's command.
An in-house monitoring center
LAIIER alerts your facilities team by email or SMS. At Eddy, an operator calls your team within minutes of an alert and stays on until the water is off.
A deployment track record
Eddy has protected buildings since 2014 and has 150,000+ active devices in the field. Clients include PCL Construction, SickKids, Lakeridge Health and Four Seasons.

What happens in a leak, step by step
- A washing machine supply hose bursts in a suite upstairs.
- Eddy H2O under the washer detects water and sends the alert over LoRaWAN.
- The building's gateway relays it. Your team and the 24/7 monitoring center are alerted at the same time.
- A shutoff rule closes the suite's Eddy IQ valve. The water stops at the source.
- Within minutes, an operator calls your on-site team through the escalation protocol.
Automatic shutoff is configured per building. Some sites use operator-coordinated isolation instead.

Eddy vs LAIIER: common questions
Does LAIIER have automatic shutoff?
None is stated. LAIIER sells the Severn WLD leak sensor and the LAIIER Cloud dashboard, which alert your team by email and SMS. Eddy can close a valve automatically or on an operator's command, with Eddy Link driving valves up to 18 inches.
What happens when an alert fires at 2 AM?
Where a valve is set to close on a leak, it shuts off the water first. Then an Eddy operator calls your on-call contact within minutes and stays on until it's handled. LAIIER emails or texts your facilities team, and with no shutoff stated, the water keeps running until someone gets there.
Does Eddy need building Wi-Fi?
No. Eddy runs its own LoRaWAN network on cellular or Ethernet gateways, so it never relies on building Wi-Fi. LoRaWAN reaches through concrete cores and mechanical rooms, with about one gateway every two floors in a tower. LAIIER also uses LoRaWAN, with gateways it supplies or on your own network.
Can Eddy help with our insurance?
Yes. Every confirmed event closes with a Leak Incident Report, documentation your carrier can use at renewal. Monitored buildings have documented premium savings of up to 20%, with deductible reductions of up to 80% documented at individual properties, though incentives vary by carrier and building.
Can Eddy protect a building during construction?
Yes. Eddy protects buildings from fit-out into occupancy. Sensors watch temporary risers and mechanical rooms, and valves can close a line after hours. The same hardware and monitoring center carry on after handover. PCL Construction builds with Eddy across Canada and the US.
How much does LAIIER cost compared to Eddy?
It depends on the building's size, the level of protection and the valves it needs. LAIIER sells Severn WLD outright or on a 60-month hardware-as-a-service contract, by custom quote. Eddy prices the hardware, the 24/7 monitoring center, project management and incident reporting as one managed service. Share their quote and we'll show what Eddy would add.
Is LAIIER a better fit for some buildings?
Yes. Where precise leak location in tight spots matters most, under lab sinks, in plant rooms or around equipment, LAIIER's trimmable 12-zone sensor tape is a strong choice. Eddy is built for buildings that need to stop the water, with a trained operator who calls your team within minutes.
