why syndii

other systems are clever.
syndii® is truly smart.

Most "smart" devices stop working the moment Wi-Fi drops or the power flickers — exactly when you need them most. syndii keeps watching for water, temperature and power issues even during outages, and reaches you over cellular so you always know what's happening at home.

why syndii

peace of mind that
doesn't depend on Wi-Fi.

We built syndii because we were tired of "smart" devices that stop working the moment Wi-Fi drops or the power flickers — which is exactly when you need them most.

Cottage and cabin owners, homeowners, and short-term rental hosts all face the same problem: you can't protect what you can't stay connected to.

syndii keeps watching for water, temperature, and power issues, even during outages, and sends alerts over cellular so you always know what's happening.

When water is detected, syndii can do more than warn you. It can automatically shut off your main water valve, stopping damage at the source before it spreads.

A simple subscription keeps everything connected and reliable.

Because real peace of mind shouldn't depend on perfect Wi-Fi — or being there in person.

3 minutes quick setup, no tools needed
24/7 monitoring, even without power*
alerts via text & email
automatic shutoff stop water damage instantly

always on. always watching.

syndii protects against the three most common — and costly — property threats.

Water leak detection

water leaks

"A 1/8" hole in a pipe can leak over 40 litres of water per hour." — Angi

Pipes can fail any time. If you're away, water damage spreads silently for hours or days. syndii alerts you the moment a sensor detects moisture — before a drip becomes a disaster.

Temperature monitoring

temperature extremes

"Frozen pipe bursts are among the costliest winter property damage — around $15,000 on average." — State Farm

Furnaces fail on the coldest nights. A frozen pipe can cost thousands — and may not be covered by insurance. syndii detects dangerous temperature drops and alerts you before pipes freeze.

Power outage monitoring

power outages

"Food begins to spoil as quickly as 4 hours into a power outage." — FDA

Rural and cottage properties are especially vulnerable to outages. syndii's built-in battery backup keeps it online even when the power isn't, and alerts you the moment the grid goes down.

the #1 question we get

"but don't I have insurance for that?"

You do — and you'll be glad you have it. But insurance and syndii do two very different jobs. One pays you back after the damage is done. The other helps make sure the damage never happens in the first place.

Insurance alone

  • Pays out after the flood, freeze or outage — once the damage is already done
  • You still lose the season to contractors, drying out and repairs
  • A $1,000–$5,000 deductible comes out of your pocket
  • Premiums often climb 20–40% after a claim
  • Many seasonal policies limit or deny claims on properties left unoccupied and unmonitored
  • It can't replace what isn't replaceable — photos, heirlooms, your time

syndii + insurance

  • Warns you the moment a leak, freeze or outage starts — before it spreads
  • Can shut your water off automatically and stop the damage at its source
  • Helps you avoid the deductible and the claim altogether
  • Keeps your claims record clean and your premiums down
  • Shows your property is actively monitored — something many insurers reward
  • Protects the season, the memories and the place you love

Insurance pays for the flood. syndii makes sure there isn't one.

is it worth it?

the honest math

A syndii starter kit is US $299 (CA $399). Monitoring is US $99/year (CA $139) — or $9.99/month (CA $12.99) — about 27¢ a day, less than a coffee a week, to know your property is safe. That's less than a typical insurance deductible, and a fraction of the ~$15,000 a single frozen-pipe loss can cost. The math isn't close.

our brand

built on three core values

Accessibility, Reliability, and Authenticity — these three values combined are what make syndii who she is.

Accessibility

syndii products had to be easy to use and setup. That's why our products connect with a single tap — and why no tools are required to install syndii. Just Plug it in, Place your sensors, and Personalize your notifications.

Reliability

Reliability isn’t a feature — it’s the whole point. syndii keeps watching through storms, outages, and long stretches when no one’s at the property. She reaches you over her own reliable network, so you’re never left wondering what’s happening back home.

Authenticity

The inventors of syndii, Elliott and Nicholas, are both cottage owners who know the stress of leaving their properties unattended. They believe in being authentic and forthcoming, and remaining focused on the cause: allowing property owners to feel stress-free and protected while away.

what customers are saying

real people. real peace of mind.

syndii texted me at 6 a.m. — a supply line behind the washer had let go. I shut the water off from my phone before I'd finished my coffee. A unit down the street flooded the same week; theirs was a $20,000 claim. Mine was a mop.

Sarah Muskoka, ON

Our lake house sits empty most of the winter. When the furnace quit during a cold snap, syndii caught the temperature dropping and we got someone over before a single pipe froze.

Mark Lake Winnipesaukee, NH

We lost power for two days at the cabin. syndii kept running on its battery and told us the moment it came back — so we knew the freezer was fine and didn't drive three hours for nothing.

Dave & Linda Northern Michigan

I rent my place out half the year. Between guests it's syndii that's watching for leaks, not me. It's paid for itself in the claims I never had to file.

Carlos Lake of the Ozarks, MO

I used to call a neighbour every cold snap to check the place. Now syndii just tells me. Easiest peace of mind I've ever bought.

Jen Whistler, BC

Setup really was three minutes — no app, no technician. The first week it caught a slow leak under the kitchen sink I'd never have found until the floor was ruined.

Tom Stowe, VT
About 27¢ a day Monitoring is just US $99/year (CA $139) or $9.99/month — less than a coffee a week. A single frozen-pipe loss averages $15,000; syndii pays for itself the first time it saves you.
Cancel anytime Monitoring is month-to-month. No contracts, no lock-in — keep it only as long as it's protecting you.
