Place the monitor
Set the main unit where USB power and reliable 2.4 GHz Wi-Fi are available in the room you want to watch.
Monitor the room, route the leak rope to the risk.
HavnCraft Sentry combines a main environmental monitor with an external leak rope so the unit can stay near power and Wi-Fi while the water sensor reaches the vulnerable spot.
Route the leak rope
Place the external sensing rope near the highest-risk water source, such as a heater, washer, sump pit or floor low point.
Connect the app
Use BLE setup, connect Wi-Fi, bind the device to your account and choose alert thresholds.
Important boundaries
What one device can and cannot represent.
Main unit placementTemperature and humidity readings represent the unit location, not every corner of a large basement.
Leak rope placementThe rope should sit near the likely leak path, such as the heater pan, washer area, sump pit or floor low point.
Large spacesUse more than one device for divided rooms, detached garages, cottages or multiple risk sources.
Network limitsRemote alerts depend on power, Wi-Fi, cloud availability and phone notification settings.
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.
