smart home alerts
Never worry about your property again.
syndii® watches over your home, cottage or cabin — and tells you the moment something goes wrong. Water, cold or power, 24/7, no Wi-Fi required.
the 3 a.m. problem
Something's going wrong.
And you're not there.
A pipe lets go while the cottage sits empty. The furnace quits on the coldest night of the year. The power drops and the freezer slowly thaws. By the time anyone notices, the damage is already done — and the season is gone.
syndii is already awake
So syndii tells you.
Instantly.
The moment a sensor detects water, a dangerous drop in temperature or a power outage, syndii sends you a text and an email — wherever you are.
When water is the problem, she can do more than warn you: syndii can shut your main valve off automatically and stop the damage at its source. You handle it from your phone, before a drip ever becomes a disaster.

Most "smart" devices quit the moment the internet drops or the power flickers — exactly when you need them most. syndii runs on built-in cellular with battery backup, so she keeps watching and keeps reaching you no matter what.
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.
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.
