Eddy vs ProSentry
Eddy vs ProSentry: which leak detection system is right for your building?
ProSentry runs on LoRaWAN like Eddy and routes alerts through AvantGuard. The critical gap is shutoff. ProSentry detects but cannot stop the water. Eddy detects AND isolates with automatic valves, an in-house monitoring center and dedicated project management.
Why choose Eddy over ProSentry
Both systems detect leaks on LoRaWAN. The difference is what happens after the alert.
Automatic shutoff, not just detection
Eddy Valve closes automatically or on operator command, triggered by sensors, flow thresholds or a call from the monitoring center. ProSentry detects leaks but does not include valve control. An alert without shutoff is an alert that hopes someone is awake.
An in-house monitoring center, not a third-party
Eddy operates a monitoring center staffed by Eddy operators trained on water incidents. ProSentry routes alerts through AvantGuard, a third-party central station with broader scope across security and fire.
Dedicated project management and customer success
Every Eddy deployment ships with a project manager who owns commissioning, alert routing and shutoff verification, plus a Building Success Manager who stays with the property after go-live.
Construction-to-operations coverage
Eddy installs during fit-out and follows the project through commissioning into operations. The same hardware and monitoring program cover both phases.
Coverage map
Detection that ends with the water off.
ProSentry detects but cannot stop the water. Eddy closes a valve automatically or on command, at the suite, the riser or the main, set up for each building. Turn the building to see where the valves sit, then run a leak.

More about Control
Detection without action is just an alert. Every sensor or meter event can trigger a valve, automatically on threshold or remotely from the dashboard. Eddy IQ is the all-in-one meter and valve for ¾"–1" lines. Eddy Link drives shutoff valves up to 18" for everything larger, provisioned and configured by Eddy.
- Eddy IQ at ¾"–1": combined meter + valve in one unit
- Eddy Link + motorized valves at mains, zones, risers, hydronics (up to 18")
- Fire mains and sprinkler systems excluded by design for life safety

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.
Eddy vs ProSentry: feature by feature
Detection alone is not the system. Here is how the two compare on shutoff, monitoring, deployment and reporting.
Automatic shutoff valves
Eddy
Eddy Valve closes automatically or on command, triggered by sensors, flow thresholds or the monitoring center. Available in sizes up to 10 inches, plus the Eddy Link controller for valves up to 18 inches.
ProSentry
Lists an automatic shut-off valve controller, but the valve-control mechanism and supported valve sizes are not documented publicly.
Why it matters: Eddy's shutoff is owned hardware in known sizes, up to 18 inches with Eddy Link, that the monitoring center can close on command. An undocumented controller is harder to stand behind at renewal.
Monitoring center model
Eddy
In-house monitoring center staffed 24/7 by Eddy operators trained specifically on water incidents.
ProSentry
Outsourced to AvantGuard, a third-party central station that handles security, fire and life safety alongside water monitoring.
Why it matters: Specialized water-incident response is the entire point of the monitoring layer. A general central station is not the same as a dedicated team.
Network protocol
Eddy
LoRaWAN, long-range low-power wireless engineered for concrete cores, mechanical rooms and tall buildings.
ProSentry
LoRaWAN with strip sensors. Same protocol family.
Why it matters: Both systems share the LoRaWAN advantage over Wi-Fi and cellular in concrete buildings. This is the point of agreement.
Sensor coverage
Eddy
Eddy H2O 3-in-1 sensors detect water, humidity and temperature. Inline flow meters monitor mains and zone risers.
ProSentry
LoRaWAN strip sensors with 10-year battery life. QR-code-based setup. Optional gas, vape and smoke detection.
Why it matters: Both cover the basics. ProSentry's gas detection is a real differentiator for NYC Local Law 157 compliance. Eddy is purpose-built around the water-loss problem.
Project management and customer success
Eddy
Dedicated project manager from kickoff through commissioning. Customer success specialist owns the property after go-live.
ProSentry
Self-serve deployment model. Less emphasis on dedicated PM and CS roles.
Why it matters: Programs that hold up at 200, 500 or 2,000 devices need a partner, not a self-serve account.
Construction-to-operations coverage
Eddy
Same hardware protects the project from rough-in through occupancy and into operations. Construction tags carry forward without rip-and-replace.
ProSentry
Operational deployment focus, primarily NYC condo and multifamily.
Why it matters: Buildings under construction need detection AND shutoff. The leaks that hit hardest happen during fit-out.
Insurance reporting
Eddy
Automated uptime, incident and response-time reports. Documented outcomes on premium savings of up to 20%, with deductible reductions of up to 80% documented at individual properties.
ProSentry
Documented NYC premium savings and a Chubb-approved New York premium discount for ProSentry users.
Why it matters: ProSentry's NYC results are real. Eddy provides the structured carrier reporting and the documented response chain that drive renewal conversations across regions and asset classes.
Geographic coverage
Eddy
North America-wide with deployments across multifamily, commercial, construction, hospitality, institutional and industrial.
ProSentry
Strong NYC metro presence, expanding nationally.
Why it matters: Portfolio operators need a vendor with depth across markets, not a regional specialist.
Per-unit submetering and resident billing
Eddy
Eddy IQ M-Bus meters and unit smart sub-metering feed your submetering company by M-Bus or API for usage-based resident billing, on the same network as detection and shutoff.
ProSentry
Per-unit leak, gas and environmental detection, with no resident-billing or submetering product.
Why it matters: For multifamily owners who want protection and usage-based resident billing on one network, Eddy covers both where ProSentry covers detection.

Talk to a leak-detection advisorFAQ
Why is automatic shutoff a deal-breaker?
A leak detection system without shutoff is an alert system. It tells you the water is escaping and waits for someone to act.
In multifamily, commercial and institutional buildings, the events that drive the largest claims happen at 2 AM, on weekends and during holidays. By the time a person arrives at the building, hundreds of liters have hit the floor. Eddy Valve closes the event automatically. The monitoring center calls minutes later to support response.
What is the difference between Eddy's monitoring center and AvantGuard?
AvantGuard is a UL-listed central monitoring station with broad scope across security, fire and life safety, supporting multiple alarm vendors. ProSentry contracts AvantGuard for its 24/7 alert layer.
Eddy operates its own monitoring center staffed by Eddy operators trained specifically on water incidents and on the building runbooks that govern Eddy deployments. The response is purpose-built for water risk.
Both systems use LoRaWAN. Why does that not settle the comparison?
LoRaWAN is the right protocol for both companies and that is genuinely the point of agreement. Both systems penetrate concrete and steel where Wi-Fi and cellular fail.
The protocol is the floor. The differentiation is what is layered on top: shutoff, in-house monitoring, dedicated project management, insurance-grade reporting and construction-to-operations coverage. Those are the layers that determine whether a water event becomes a claim.
Is ProSentry a good fit for some buildings?
ProSentry has earned a strong NYC condo footprint and competitive pricing for detection-only deployments, particularly where the budget priority is sensor coverage and the building has its own response infrastructure.
Eddy is built for buildings where the response chain matters as much as the sensor, where automatic shutoff is required for insurance and where construction-to-operations coverage and dedicated project management drive the program.
What about NYC Local Law 157 and gas detection?
ProSentry's gas, vape and smoke detection capability is a real differentiator for NYC Local Law 157 compliance and for properties that want a single LoRaWAN backbone for multiple sensor types.
Eddy is purpose-built around water loss prevention. For NYC properties that need both, the most common pattern is to standardize the water-loss program on Eddy and use the appropriate compliance product for gas detection.
Does Eddy work outside of New York City?
Yes. Eddy operates across North America with deployments spanning multifamily, commercial, construction, hospitality, institutional and industrial assets. ProSentry's footprint is concentrated in the NYC metro and expanding nationally.
Portfolio operators with assets across multiple markets typically standardize on a vendor with broader regional depth.
What does Eddy cost compared to ProSentry?
ProSentry leads with aggressive sensor pricing on a $1-per-sensor-per-month subscription. Eddy bundles hardware, automatic shutoff valves, the in-house monitoring center, dedicated project management and insurance-grade reporting into a single managed-service relationship.
The right comparison is total cost of risk, not unit price. A single prevented loss in a commercial building offsets the lifetime cost of the system. Talk to the Eddy team for a tailored quote against your portfolio.
