Eddy vs NOWA
Eddy vs NOWA: which leak detection system is right for your building?
NOWA packs a lot of sensors per master unit. Eddy adds the network reach, the monitoring center and the documented insurance outcomes that turn the install into a renewal conversation.
Why choose Eddy over NOWA
Detection density is a feature. Documented response and insurance outcomes are the program.
A staffed monitoring center
NOWA delivers real-time alerts. Eddy adds a 24/7 monitoring center that calls your team minutes after the alert and supports response per the building's runbook.
LoRaWAN reach in concrete and steel
NOWA runs on proprietary wireless. Eddy uses LoRaWAN, a long-range protocol engineered for concrete cores and mechanical rooms where proprietary radios drop out.
Documented insurance outcomes
Eddy's clients have driven premium savings of up to 20%, with deductible reductions of up to 80% documented at individual properties. Aon's whitepaper independently validates the model.
Coverage map
Sensor density, plus people on every alert.
NOWA does sensor density and zone shutoff well. Eddy adds LoRaWAN reach and a staffed monitoring center that follows every alert. Run a leak to see the response.

The system
Detect, control and respond, in one managed program.
Sensors sit where leaks start and meters watch the flow. Valves close on the rules you set, and a 24/7 monitoring center follows each alert until your team has eyes on it.

Detect
Two ways to find a leak before it finds a unit.
Sensors sit where leaks start, and meters watch the flow for the leaks no sensor can reach.

Point-of-leak
Flow-based
Control
Valves that close the water before it closes the unit.
Valves close on the rules you set, automatically on a threshold or remotely from the dashboard.
4 close-ups · select one to zoom in
Respond
A live monitoring center that closes the loop.
Alerts go through Eddy's cloud to a 24/7 monitoring center, and an operator calls your team until someone has eyes on the water.

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.
- An operator confirms the alert and calls your on-site team through the escalation protocol.
Automatic shutoff is configured per building. Some sites use operator-coordinated isolation instead.
More about Respond
Eddy's 24/7 monitoring center confirms every alert, escalates per your contact list and stays on the line until the water is off and the on-site team has eyes on it.
- Configurable automation rules per zone and time of day
- Trained operators on duty 24/7
- Escalation: automation → property manager → emergency contact, on your list
- Submetering and consumption data for billing, conservation and ESG reporting

Eddy vs NOWA: feature by feature
Both systems include sensors and shutoff. Here is how the response chain, network and reporting actually compare.
24/7 monitoring center
Eddy
Live operators support, confirm and escalate every alert.
NOWA
Self-monitored by app out of the box. Central-station monitoring is available only through a third-party alarm dealer, not a NOWA-run water team.
Why it matters: An alert at 2 AM means nothing without action. Eddy puts a human on the line minutes after the alert.
Network protocol
Eddy
LoRaWAN, long-range wireless engineered for concrete and steel.
NOWA
Z-Wave mesh for sensors and valves, with Ethernet, WiFi or cellular for reporting. Range and scale are tighter than LoRaWAN in large buildings.
Why it matters: LoRaWAN penetrates concrete cores and mechanical rooms where proprietary radios drop out.
Documented insurance outcomes
Eddy
Premium savings of up to 20%, with deductible reductions of up to 80% documented at individual properties documented; Aon whitepaper independently validates the model.
NOWA
Limited documented insurance outcomes.
Why it matters: Underwriters reward structured mitigation evidence with premium and deductible reductions.
Sensor density
Eddy
Sensors deploy across humidity, temperature and water presence on a single LoRaWAN network with no master-unit limit per zone.
NOWA
Up to 64 sensors per master unit; gold-plated probes; self-testing sensors.
Why it matters: Both vendors get sensors where they need to be. Network architecture changes how the system scales building by building.
Automatic shutoff
Eddy
Eddy Valve closes the main on a confirmed event, and Eddy Link drives shutoff valves up to 18 inches.
NOWA
Zone-based partial shutoff capability.
Why it matters: The right shutoff strategy depends on the building. Eddy provisions and configures the valves on the same network.
Insurance reporting
Eddy
Automated uptime, incident and response-time reports.
NOWA
Operational dashboards; carrier-formatted reporting not standard.
Why it matters: Insurers want structured mitigation evidence at renewal, not raw exports.
Portfolio-level features
Eddy
Multi-property dashboards, role-based access and rolled-up reporting for owners and operators with hundreds of buildings.
NOWA
Per-building focus; portfolio-level features are limited.
Why it matters: Owners and operators evaluating across portfolios need rolled-up visibility and structured comparisons.
Per-unit submetering and resident billing
Eddy
Eddy IQ M-Bus meters and unit smart sub-metering capture unit-level consumption and feed your submetering company by M-Bus or API for usage-based resident billing, on the same network that runs leak detection, shutoff and a staffed 24/7 monitoring center.
NOWA
Leak detection and zone-based shutoff only. The PRESENCE app graphs leak and system status, not metered water usage, so there is no per-unit consumption data for usage-based resident billing.
Why it matters: In condos and multi-residential buildings, fair usage-based billing and leak protection ideally run off one metering layer instead of a separate submetering install.

How is Eddy different from NOWA?
Both vendors include sensors and shutoff. Where Eddy differs is the network (LoRaWAN vs proprietary wireless), the staffed 24/7 monitoring center that calls your team after every alert, and the documented insurance outcomes that drive renewal conversations.
Does Eddy work in older Canadian buildings?
Yes. Eddy retrofits into existing buildings without rip-and-replace. Eddy Link drives shutoff valves up to 18 inches and reads water meters, all provisioned and configured by Eddy.
What insurance documentation does Eddy provide?
Automated uptime, incident and response-time reports. Operators have used the documentation to drive premium savings of up to 20%, with deductible reductions of up to 80% documented at individual properties.
What happens after an alert in the Eddy program?
Sensors page your team in seconds and the automatic shutoff isolates the riser when triggered. The Eddy monitoring center calls your on-call contact minutes later, supports response per the building's runbook and stays on the line until the team confirms resolution. Every event closes with a Leak Incident Report.
