EDGE Essential WiFi Flood Detector with its yellow water-sensing rope, sensitive along its full length

What property managers tell us, and how we fix it

  • A slow leak behind a water heater that nobody sees.

    The leak-sensing cable detects water along its whole length and alerts by call, text and email.

  • Pipes at risk in an empty, cold unit.

    A frost alert calls you when a unit drops below the limit you set, before the pipes freeze.

  • Mold nobody sees until a tenant complains.

    Every EDGE monitor calculates a Mold Index from temperature and humidity and predicts mold risk before mold is visible.

  • One water bill and one heating bill for the whole building.

    Cellular water meters on suite lines, and a BLOCK Pulse Counter on heat meters with a pulse output, log each unit’s use. Export any period to Excel for tenant sub-billing.

  • Too many buildings to check in person.

    Share every device with your team; everyone gets the alarm at once.

Your phone rings, not just a text.

Water on the rope, or a unit colder than your low limit: MaxLinc calls, texts and emails the people you choose.

Set up in 3 steps

  1. Lay the rope where water collects

    Riser and mechanical rooms, under water heaters, in empty units.

  2. Connect to WiFi, or it’s online with Cellular

    WiFi uses the building’s 2.4 GHz network. Cellular needs only a cell signal.

  3. Set your limits. Get the call.

    Choose who gets alerts, and a low limit such as 5 °C for empty units.

Water & heat submetering

One bulk bill hides every leak in the building

You pay for every litre the building uses and find out sixty days later. A MaxLinc cellular meter on a suite line or stack reports on its own: no gateway, no building WiFi. Add a BLOCK Pulse Counter to heat meters with a pulse output and each unit’s heating use is logged too, ready for tenant sub-billing.

From $275 per meter

First 5 years of service included, then about $8.89/yr per meter.

Frequently asked questions

Do I need a gateway or a monthly subscription?

No gateway: each EDGE connects to the building’s 2.4 GHz WiFi, or to the cell network on Cellular models. No subscription required on WiFi: live data, every alarm, email and push alerts, 45 days of history and Excel export stay free. Premium is included in each device’s first year, then optional at about $17.78/yr per device for full history, advanced reports and new people. Cellular: year 1 included, then about $26.67/yr per device, which covers the network and Premium.

How do the leak and freeze alerts work?

The rope senses water anywhere along its length and can be extended up to 100 m (about 330 ft) to reach riser rooms, mechanical rooms and empty units. The EDGE also logs temperature and humidity, so you can set a frost alert: a low limit for freeze risk. When the rope gets wet or a reading leaves your limits, MaxLinc calls, texts and emails the people you choose, and the alarm repeats until the reading is back in range. A team member can snooze it for up to 24 hours by acknowledging it and entering a reason. Email and push alerts are free; texts cost about 1.5¢ and calls about 3.7¢ after the about $3.70 credit included with each device.

Can it warn me about damp and mold in units?

Yes. Every EDGE monitor logs temperature and humidity and calculates a Mold Index, a predictive score of mold-growth risk, so damp in a basement, suite or lobby warns you before mold is visible. The EDGE Air WiFi adds CO2 and TVOC for indoor-air complaints. You can fix ventilation or a moisture source before mold spreads and turns into a remediation bill or a tenant dispute.

Will the sensors keep working in a power outage or WiFi dropout?

The loggers run on batteries (4 AA alkaline batteries, about 2 years, with optional USB-C power), so they keep recording during a power outage. Readings are buffered and uploaded once the connection returns, so you keep a continuous record even if WiFi briefly drops. Cellular models don’t need your router: on USB-C power, they report a power cut at their next recording (every 10 minutes by default), not instantly, by push, email and text.

Can staff, contractors and owners each get their own access?

Yes. The cloud dashboard shares by role: give a property manager full control, give maintenance staff or contractors alert access, and give owners read-only visibility, all from one account. Everyone sees the same live readings and alert history without sharing a login, which helps across a portfolio of buildings.

Can I meter water per suite?

Yes, with the MaxLinc cellular ultrasonic water meter. It comes in DN20 and DN25 (3/4" and 1") for suite lines, stacks, irrigation feeds and deduct meters, and it reports over the cell network with no gateway or building WiFi. It has no moving parts, an IP68 submersible body and a sealed lithium battery rated for about 6 years at one read per day. One toilet running at about 1 L/min wastes about 525 m³ a year. Recovering water costs from residents is regulated province by province, but you do not need billing rights to stop paying for a leak.

Can I sub-bill heat as well as water?

Yes, where each suite has a heat meter with a pulse output. A BLOCK Pulse Counter counts those pulses and logs each unit’s heating use to the cloud, next to your water meters. Export any period to Excel for your billing system or sub-billing spreadsheet. Recovering utility costs from residents is regulated province by province, so check the rules where your building is.

Managing several buildings?

Each building gets its own monitors in one account, with alerts sent to the right people.
