Eddy vs ZoJacks
Eddy vs ZoJacks: which leak detection system is right for your building?
ZoJacks's hub-based topology works well in line-of-sight spaces. Eddy's LoRaWAN network, in-house monitoring center and dedicated project management are built for the rest of the building.
Why choose Eddy over ZoJacks
Speed of detection matters less than what happens next.
An in-house monitoring center, not a claim
Eddy's monitoring center is staffed 24/7 by operators trained on each building's runbook. They call your team minutes after the alert.
LoRaWAN, not hub-based wireless
ZoJacks runs on a hub topology with WiFi/Ethernet/SIM connectivity. Eddy uses LoRaWAN, a long-range protocol that penetrates concrete cores and mechanical rooms.
Dedicated project management
Every Eddy deployment ships with a project manager. Commissioning, alert routing and shutoff verification are part of the program, not a checklist for the building staff.
Eddy vs ZoJacks: feature by feature
Detection speed is a number. Response, network and accountability are the system.
24/7 monitoring center
Eddy
In-house monitoring center; live operators support every alert.
ZoJacks
Offers UL-listed Five Diamond central-station monitoring for about $15 per month. That is alarm-industry monitoring, not a water-domain team working from your building's system map.
Why it matters: The right comparison is who picks up the phone at 2 AM, not whether the marketing page says 24/7.
Network protocol
Eddy
LoRaWAN, long-range wireless engineered for concrete and steel.
ZoJacks
Hub and sensors on a cellular network, marketed as independent of building WiFi.
Why it matters: Hub topologies require line-of-sight or repeaters; LoRaWAN penetrates concrete cores and mechanical rooms.
Dedicated project manager
Eddy
Each deployment ships with a project manager for commissioning, alert routing and shutoff verification.
ZoJacks
Self-serve installation and commissioning model.
Why it matters: Install-and-hope is not a strategy. Eddy ships with a managed program from day one.
Documented insurance outcomes
Eddy
Up to $150K deductible reductions and up to 20% premium savings documented; Aon whitepaper independently validates the model.
ZoJacks
Limited documented insurance outcomes.
Why it matters: Underwriters reward structured mitigation evidence with premium and deductible reductions.
Sensor ecosystem
Eddy
Humidity, temperature and water-presence sensors plus rope and probe attachments; common-area, in-suite and mechanical-room coverage.
ZoJacks
Wireless sensors plus air quality sensors and range extenders; WaterStop shutoff valve.
Why it matters: Both vendors get sensors where they need to be. Eddy's coverage list maps to insurer Coverage & System Design checklists.
Track record at scale
Eddy
140,000+ active devices, $128M prevented in 2025, named multi-asset case studies.
ZoJacks
Early-stage with a light public track record and limited documented deployments at scale.
Why it matters: Risk managers reward documented track records, especially in multifamily where claim severity is high.
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.
ZoJacks
Leak detection and shutoff; the app tracks whole-system water usage for conservation goals, not certified per-unit consumption for usage-based resident billing.
Why it matters: In multifamily and condos, a metering layer that also feeds resident billing turns the same install into a cost-recovery tool, not just leak protection.

ZoJacks runs on a hub-based wireless topology and emphasizes detection speed. Eddy runs on LoRaWAN engineered for concrete cores, ships with a dedicated project manager and operates an in-house 24/7 monitoring center that calls your team after every alert.
Yes, in real buildings. Hub-based wireless and WiFi rely on line-of-sight or repeater chains. LoRaWAN's 915 MHz long-range protocol penetrates concrete cores and steel decks where hub radios drop out.
One Eddy gateway typically covers two floors of a high-rise. Hub topologies in the same building usually require multiple repeaters and dead-zone surveys.
Automated uptime, incident and response-time reports. Operators have used the documentation to drive deductible reductions of up to $150K and premium savings of up to 20%.
Eddy bundles hardware, the monitoring center, dedicated project management and insurance-grade reporting into a single managed-service relationship.
