Clear answers before you install or buy.
No mould-detection, flood-prevention or certification claims are made without evidence.
Where should I place HavnCraft Sentry?
Place the main unit where USB power and reliable Wi-Fi are available. Route the external leak rope to the highest-risk water source.
Does it work without Wi-Fi?
Local alarm behaviour is designed to continue for key events, but phone notifications and remote monitoring require cloud connectivity.
Does it require a subscription?
Core alerts, device health and essential history are intended to remain available without a mandatory subscription.
What happens during a power outage?
USB-C is recommended for continuous monitoring. AA battery runtime and backup behaviour depend on final hardware and firmware validation.
How long do the AA batteries last?
Battery runtime testing is in progress. We will publish verified numbers only after final firmware and hardware testing.
Can one device cover my whole basement?
One device monitors the main unit location and the routed leak rope. Large or divided spaces may need multiple devices.
Is it a smoke, CO or mould detector?
No. HavnCraft Sentry is not a smoke alarm, carbon-monoxide alarm or certified mould detector.
What is included in the box?
The assembled monitor, selected standard shell, external leak rope, USB-C cable and quick setup guide are included with the standard kit.
HavnCraft Sentry is an early-warning environmental monitor. It is not a life-safety device, smoke alarm, carbon-monoxide alarm, flood-prevention system or certified mould detector. Alerts depend on device placement, power, network availability and notification settings.
